Illness Issues

What is the current state of affairs with measles, mumps, and rubella in the Us?

In 2019, a provisional full of i,242 cases of measles from 31 states were reported to CDC. This was the largest number reported in a single year since 1992; 73% of cases were associated with outbreaks among unvaccinated people in New York. These outbreaks were independent and stopped before the cease of 2019. Between Jan 1 and Baronial 19, 2020, just 12 measles cases were reported by vii jurisdictions. Limited travel as a result of the COVID-19 pandemic drastically reduced opportunities for travelers infected with measles to enter or travel within the U.s.a.. CDC measles surveillance updates can be institute at www.cdc.gov/measles/cases-outbreaks.html.

Since the pre-vaccine era, there has been a more than 99% decrease in mumps cases in the United States. However, outbreaks nonetheless occasionally occur. In 2006, there was an outbreak affecting more than 6,584 people in the United States, with many cases occurring on college campuses. In 2009, an outbreak started in close-knit religious communities and schools in the Northeast, resulting in more than 3,000 cases. Since 2015, numerous outbreaks have been reported across the US, in college campuses, prisons, and close-knit communities, including a large outbreak in northwest Arkansas where well-nigh 3,000 cases were reported in 2016. These outbreaks have shown that when people with mumps have shut contact with a lot of other people (such as among residential college students and families in close-knit communities) mumps can spread even amidst vaccinated people. However, outbreaks are much larger in areas where vaccine coverage rates are lower. A conditional total of 3,484 cases of mumps were reported to CDC in 2019.

Rubella was alleged eliminated (the absence of owned manual for 12 months or more) from the United States in 2004. Fewer than 10 cases (primarily import-related) have been reported annually in the Us since elimination was alleged. Rubella incidence in the United states of america has decreased past more 99% from the pre-vaccine era. A conditional full of 3 cases of rubella, and no cases of congenital rubella syndrome, were reported in 2019.

How serious are measles, mumps, and rubella?

Measles can lead to serious complications and death, even with modern medical care. The 1989–1991 measles outbreak in the U.S. resulted in more than 55,000 cases and more than 100 deaths. In the The states, from 1987 to 2000, the almost usually reported complications associated with measles infection were pneumonia (6%), otitis media (7%), and diarrhea (eight%). For every 1,000 reported measles cases in the U.s., approximately one case of encephalitis and two to three deaths resulted. The risk for death from measles or its complications is greater for infants, young children, and adults than for older children and adolescents.

Mumps well-nigh commonly causes fever and parotitis. Up to 25% of persons with mumps have few or no symptoms. Complications of mumps include orchitis (inflammation of the testicle) and oophoritis (inflammation of the ovary). Other complications of mumps include pancreatitis, deafness, aseptic meningitis, and encephalitis. Mumps disease is typically milder, with fewer complications, in fully vaccinated example patients.

Rubella is generally a mild illness with low-class fever, lymphadenopathy, and malaise. Upwardly to 50% of rubella virus infections are subclinical. Complications can include thrombocytopenic purpura and encephalitis. Rubella virus is teratogenic and infection in a meaning woman, especially during the first trimester can upshot in miscarriage, stillbirth, and birth defects including cataracts, hearing loss, mental retardation, and built heart defects.

What are the signs and symptoms healthcare providers should look for in diagnosing measles?

Healthcare providers should suspect measles in patients with a delirious rash illness and the clinically uniform symptoms of cough, coryza (runny nose), and/or conjunctivitis (crimson, watery optics). The disease begins with a prodrome of fever and malaise before rash onset. A clinical case of measles is defined as an illness characterized by

• a generalized rash lasting 3 or more days, and • a temperature of 101°F or higher (38.3°C or college), and • cough, coryza, and/or conjunctivitis.

Koplik spots, a rash present on mucous membranes, are considered pathognomonic for measles. Koplik spots occur from 1 to 2 days before the measles rash appears to 1 to two days afterward. They announced equally punctate blue-white spots on the bright red background of the buccal mucosa. Pictures of measles rash and Koplik spots tin be found at www.cdc.gov/measles/nigh/photos.html.

Providers should be particularly enlightened of the possibility of measles in people with fever and rash who have recently traveled abroad or who have had contact with international travelers.

Providers should immediately isolate and report suspected measles cases to their local wellness department and obtain specimens for measles testing, including viral specimens for confirmation and genotyping. Providers should also collect blood for serologic testing during the first clinical encounter with a person who has suspected or probable measles.

What should our clinic practise if we suspect a patient has measles?

Measles is highly contagious. A person with measles is infectious up to 4 days before through 4 days later the solar day of rash onset. Patients with suspected measles should exist isolated for four days afterward they develop a rash. Airborne precautions should be followed in healthcare settings past all healthcare personnel. The preferred placement for patients who require airborne precautions is in a single-patient airborne infection isolation room. Providers should immediately isolate and study suspected measles cases to their local health department and obtain specimens for measles testing, including serum sample for measles serologic testing and a throat swab (or nasopharyngeal swab) for viral confirmation.

Measles is a nationally notifiable illness in the U.S.; healthcare providers should study all cases of suspected measles to public health regime immediately to aid reduce the number of secondary cases. Do not wait for the results of laboratory testing to report clinically-suspected measles to the local health department.

More than information on measles illness, diagnostic testing, and infection command can exist found at www.cdc.gov/measles/hcp/alphabetize.html.

How long does information technology take to show signs of measles, mumps, and rubella subsequently being exposed?

For measles, there is an average of 10 to 12 days from exposure to the appearance of the first symptom, which is usually fever. The measles rash doesn't normally appear until approximately 14 days afterward exposure (range: vii to 21 days), and the rash typically begins 2 to 4 days afterward the fever begins. The incubation period of mumps averages 16 to 18 days (range: 12 to 25 days) from exposure to onset of parotitis. The incubation period of rubella is 14 days (range: 12 to 23 days). However, as noted above, up to half of rubella virus infections cause no symptoms.

Vaccine Recommendations Back to top

What are the current recommendations for the apply of MMR vaccine?

The nearly recent comprehensive ACIP recommendations for the utilise of MMR vaccine were published in 2013 and are bachelor at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf. MMR vaccine is recommended routinely for all children at age 12 through xv months, with a 2d dose at age 4 through 6 years. The second dose of MMR can exist given every bit early equally four weeks (28 days) afterwards the first dose and be counted as a valid dose if both doses were given after the child'due south first birthday. The second dose is non a booster, simply rather is intended to produce immunity in the small number of people who fail to respond to the first dose.

Adults with no evidence of immunity (evidence of immunity is defined as documented receipt of one dose [two doses four weeks apart if loftier risk] of live measles virus-containing vaccine, laboratory show of amnesty or laboratory confirmation of disease, or nascence before 1957) should become 1 dose of MMR vaccine unless the adult is in a high-risk grouping. High-take a chance people need 2 doses and include schoolhouse-historic period children, healthcare personnel, international travelers, and students attention post-high school educational institutions.

Live attenuated measles vaccine became bachelor in the U.S. in 1963. An ineffective, inactivated measles vaccine was also available in the U.S. in 1963–1967. Combined MMR vaccine (MMRII, Merck) was licensed in 1971. For people who previously received a dose of measles vaccine in 1963–1967 and are unsure which type of vaccine it was, or are sure information technology was inactivated measles vaccine, that dose should exist considered invalid and the patient revaccinated as age- and risk-advisable with MMR vaccine. At the discretion of the country public wellness section, anyone exposed to measles in an outbreak setting tin can receive an additional dose of MMR vaccine even if they are considered completely vaccinated for their age or risk status.

What is considered acceptable evidence of immunity to measles?

Acceptable presumptive evidence of amnesty confronting measles includes at to the lowest degree one of the following:

• written documentation of acceptable vaccination: • laboratory bear witness of immunity • laboratory confirmation of measles (exact history of measles does not count) • nascence before 1957

Although birth earlier 1957 is considered acceptable evidence of measles immunity, healthcare facilities should consider vaccinating unvaccinated personnel born before 1957 who do not have other prove of immunity with 2 doses of MMR vaccine (minimum interval 28 days).

During an outbreak of measles, healthcare facilities should recommend two doses of MMR vaccine at the appropriate interval for unvaccinated healthcare personnel regardless of nascency year if they lack laboratory evidence of measles amnesty.

For which adults are 0, 1, or 2 doses of MMR vaccine recommended to foreclose measles?

Null, one, or two doses of MMR vaccine are needed for the adults described beneath.

Zero doses:

• adults born before 1957 except healthcare personnel* • adults born 1957 or after who are at depression risk (i.e., non an international traveler or healthcare worker, or person attending college or other post-loftier school educational institution) and who have already received ane or more than documented doses of alive measles vaccine • adults with laboratory testify of amnesty or laboratory confirmation of measles

One dose of MMR vaccine:

• adults born 1957 or later who are at low risk (i.e., not an international traveler, healthcare worker, or person attending college or other mail-high school educational institution) and have no documented vaccination with live measles vaccine and no laboratory prove of immunity or prior measles infection

2 doses of MMR vaccine:

� loftier-risk adults without any prior documented live measles vaccination and no laboratory evidence of amnesty or prior measles infection, including:

Persons who previously received a dose of measles vaccine in 1963–1967 and are unsure which type of vaccine it was, or are certain it was inactivated measles vaccine, should be revaccinated with either one (if low-take a chance) or ii (if high-risk) doses of MMR vaccine.

* Healthcare personnel born before 1957 should be considered for MMR vaccination in the absenteeism of an outbreak, but are recommended for MMR vaccination during outbreaks.

Given the risk of outbreaks of measles in the U.S., should all healthcare personnel, including those born earlier 1957, have ii doses of MMR vaccine?

Although birth before 1957 is considered adequate evidence of measles immunity for routine vaccination, healthcare facilities should consider vaccinating unvaccinated healthcare personnel (HCP) born before 1957 who do not have laboratory evidence of measles immunity, laboratory confirmation of disease, or vaccination with two appropriately spaced doses of MMR vaccine.

Nevertheless, during a local outbreak of measles, all healthcare personnel, including those born before 1957, are recommended to have 2 doses of MMR vaccine at the advisable interval if they lack laboratory evidence of measles.

Healthcare facilities should bank check with their state or local wellness department's immunization program for guidance. Access contact information hither: www.immunize.org/coordinators.

If there is an outbreak in my area, can we vaccinate children younger than 12 months?

MMR tin be given to children as young as 6 months of historic period who are at high run a risk of exposure such every bit during international travel or a community outbreak. However, doses given Before 12 months of age cannot be counted toward the 2-dose series for MMR.

How does beingness born before 1957 confer immunity to measles?

People built-in before 1957 lived through several years of epidemic measles before the starting time measles vaccine was licensed in 1963. Every bit a event, these people are very probable to have had measles affliction. Surveys advise that 95% to 98% of those born before 1957 are immune to measles. Persons born before 1957 can exist presumed to be immune. Withal, if serologic testing indicates that the person is not allowed, at least 1 dose of MMR should be administered.

Why is a second dose of MMR necessary?

Approximately vii% of people do not develop measles immunity afterward the beginning dose of vaccine. This occurs for a diversity of reasons. The 2d dose is to provide another adventure to develop measles immunity for people who did non respond to the first dose. Nearly 97% of people develop amnesty to measles afterwards two doses of measles-containing vaccine.

Are at that place any situations where more than ii doses of MMR are recommended?

There are two circumstances when a third dose of MMR is recommended. ACIP recommends that women of childbearing age who have received 2 doses of rubella-containing vaccine and have rubella serum IgG levels that are not clearly positive should receive i additional dose of MMR vaccine (maximum of three doses). Farther testing for serologic prove of rubella amnesty is not recommended. MMR should not be administered to a pregnant woman.

In 2018, ACIP published guidance for MMR vaccination of people at increased risk for acquiring mumps during an outbreak. People previously vaccinated with 2 doses of a mumps virus�containing vaccine who are identified by public health authorities every bit being role of a group or population at increased chance for acquiring mumps because of an outbreak should receive a third dose of a mumps virus�containing vaccine (MMR or MMRV) to improve protection confronting mumps disease and related complications. More information about this recommendation is bachelor at www.cdc.gov/mmwr/volumes/67/wr/pdfs/mm6701a7-H.pdf.

When is information technology advisable to use MMR vaccine for measles post-exposure prophylaxis?

MMR vaccine given inside 72 hours of initial measles exposure can reduce the risk of getting sick or reduce the severity of symptoms. Another option for exposed, measles-susceptible individuals at loftier take a chance of complications who cannot be vaccinated is to give immunoglobulin (IG) within half dozen days of exposure. Practice not administer MMR vaccine and IG simultaneously, as the IG invalidates the vaccine.

Information on post-exposure prophylaxis for measles can be found in the 2013 ACIP guidance at world wide web.cdc.gov/mmwr/pdf/rr/rr6204.pdf, page 24.

Do whatsoever adults need "booster" doses of MMR vaccine to foreclose measles?

No. Adults with evidence of amnesty exercise not need any farther vaccines. No "booster" doses of MMR vaccine are recommended for either adults or children. They are considered to have life-long immunity once they accept received the recommended number of MMR vaccine doses or take other evidence of immunity.

Many people who were young children in the 1960s practice not accept records indicating what type of measles vaccine they received in the mid-1960s. What measles vaccine was almost frequently given in that time period? That guidance would assist many older people who would prefer non to be revaccinated.

Both killed and live attenuated measles vaccines became bachelor in 1963. Live attenuated vaccine was used more oftentimes than killed vaccine. The killed vaccine was found to be not constructive and people who received it should exist revaccinated with alive vaccine. Without a written record, it is non possible to know what type of vaccine an individual may take received. And so persons born during or after 1957 who received killed measles vaccine or measles vaccine of unknown blazon, or who cannot document having been vaccinated or having laboratory-confirmed measles disease should receive at to the lowest degree i dose of MMR. Some people at increased risk of exposure to measles (such as healthcare professionals and international travelers) should receive 2 doses of MMR separated by at to the lowest degree 4 weeks.

Exercise people who received MMR in the 1960s need to have their dose repeated?

Non necessarily. People who have documentation of receiving live measles vaccine in the 1960s practise not need to be revaccinated. People who were vaccinated prior to 1968 with either inactivated (killed) measles vaccine or measles vaccine of unknown blazon should exist revaccinated with at least 1 dose of live attenuated measles vaccine. This recommendation is intended to protect people who may have received killed measles vaccine which was bachelor in the Us in 1963 through 1967 and was not effective. People vaccinated before 1979 with either killed mumps vaccine or mumps vaccine of unknown type who are at high chance for mumps infection (such as people who piece of work in a healthcare facility) should be considered for revaccination with ii doses of MMR vaccine.

I understand that ACIP changed its definition of evidence of immunity to measles, rubella, and mumps in 2013. Please explicate.

In the 2013 revision of its MMR vaccine recommendations ACIP includes laboratory confirmation of disease as evidence of immunity for measles, mumps, and rubella. ACIP removed md diagnosis of illness as evidence of immunity for measles and mumps. Md diagnosis of illness had not previously been accepted as evidence of immunity for rubella. With the subtract in measles and mumps cases over the final 30 years, the validity of physician-diagnosed disease has become questionable. In addition, documenting history from doctor records is non a practical choice for most adults. The 2013 MMR ACIP recommendations are available at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

Is there anything that can exist done for unvaccinated people who accept already been exposed to measles, mumps, or rubella?

Measles vaccine, given as MMR, may exist effective if given within the first 3 days (72 hours) afterward exposure to measles. Immune globulin may be effective for as long as 6 days after exposure. Postexposure prophylaxis with MMR vaccine does non prevent or change the clinical severity of mumps or rubella. Withal, if the exposed person does not take evidence of mumps or rubella immunity they should be vaccinated since non all exposures issue in infection.

What are the electric current ACIP recommendations for use of immune globulin (IG) for measles, mumps, and rubella post-exposure prophylaxis?

In the 2013 revision of its MMR vaccine recommendations ACIP expanded the use of postal service-exposure IG prophylaxis for measles. Intramuscular IG (IGIM) should be administered to all infants younger than 12 months who take been exposed to measles. The dose of IGIM is 0.v mL/kg of body weight; the maximum dose is 15 mL. Alternatively, MMR vaccine tin be given instead of IGIM to infants age 6 through 11 months, if it can be given within 72 hours of exposure.

Pregnant women without show of measles immunity who are exposed to measles should receive an intravenous IG (IGIV) dose of 400 mg/kg of body weight. Severely immunocompromised people, irrespective of show of measles immunity or vaccination, who have been exposed to measles should receive an IGIV dose of 400 mg/kg of body weight.

For persons already receiving IGIV therapy, administration of at least 400 mg/kg torso weight within 3 weeks before measles exposure should be sufficient to prevent measles infection. For patients receiving subcutaneous immune globulin (IGSC) therapy, administration of at to the lowest degree 200 mg/kg body weight for 2 consecutive weeks earlier measles exposure should exist sufficient.

Other people who do not accept evidence of measles immunity can receive an IGIM dose of 0.5 mL/kg of trunk weight. Give priority to people who were exposed to measles in settings where they have intense, prolonged close contact (such as household, child care, classroom, etc.). The maximum dose of IGIM is fifteen mL.

IG is non indicated for persons who accept received i dose of measles-containing vaccine at age 12 months or older unless they are severely immunocompromised. IG should not be used to command measles outbreaks.

IG has not been shown to preclude mumps or rubella infection after exposure and is not recommended for that purpose.

Nosotros oft encounter higher students who lack vaccination records, but whose titer results testify they are not immune to some combination of measles, rubella, and/or mumps. What blazon of vaccine should these students receive?

Single antigen vaccine is no longer available in the U.Due south.; the student should get the combined MMR vaccine. If a college educatee or other person at increased risk of exposure cannot produce written documentation of either immunization or affliction, and titers are negative, they should receive two doses of MMR.

I have patients who claim to think receiving MMR vaccine simply take no written record, or whose parents report the patient has been vaccinated. Should I accept this as testify of vaccination?

No. Self-reported doses and history of vaccination provided past a parent or other caregiver are non considered to be valid. Yous should only accept a written, dated record as prove of vaccination.

Under what circumstances should adults be considered for testing for measles-specific antibiotic prior to getting vaccinated?

Adults without evidence of immunity and no contraindications to MMR vaccine tin be vaccinated without testing. Only adults without evidence of immunity might be considered for testing for measles-specific IgG antibody, only testing is not needed prior to vaccination.

CDC does not recommend measles antibiotic testing after MMR vaccination to verify the patient'south immune response to vaccination.

Two documented doses of MMR vaccine given on or after the first birthday and separated by at least 28 days is considered proof of measles immunity, co-ordinate to ACIP. Documentation of appropriate vaccination supersedes the results of serologic testing for measles, mumps, rubella, and varicella.

A patient born in 1970 has a history of measles disease and is also immunosuppressed due to multiple myeloma. The patient wants to travel to Africa, but is concerned about the measles exposure risk. Should the patient receive the MMR vaccine?

A history of having had measles is not sufficient evidence of measles amnesty. A positive serologic test for measles-specific IgG will confirm that the person is immune and is non at risk of infection regardless of the multiple myeloma. Multiple myeloma is a hematologic cancer and is considered immunosuppressive so MMR vaccine is contraindicated in this person.

We have developed patients in our exercise at high risk for measles, including patients going back to college or preparing for international travel, who don't remember always receiving MMR vaccine or having had measles disease. How should we manage these patients?

You accept two options. You can test for amnesty or you can just give two doses of MMR at to the lowest degree 4 weeks apart. There is no impairment in giving MMR vaccine to a person who may already be immune to ane or more of the vaccine viruses. If you or the patient opt for testing, and the tests indicate the patient is non immune to one or more of the vaccine components, requite your patient 2 doses of MMR at least 4 weeks autonomously. If any examination results are indeterminate or equivocal, consider your patient nonimmune. ACIP does non recommend serologic testing later on vaccination considering commercial tests may non exist sensitive enough to reliably discover vaccine-induced immunity.

I have a 45-year-sometime patient who is traveling to Haiti for a mission trip. She doesn't recollect ever getting an MMR booster (she didn't go to college and never worked in health intendance). She was rubella immune when meaning twenty years ago. Her measles titer is negative. Would you recommend an MMR booster?

ACIP recommends two doses of MMR given at least 4 weeks apart for any developed born in 1957 or later who plans to travel internationally. In that location is no impairment in giving MMR vaccine to a person who may already be allowed to ane or more of the vaccine viruses.

A patient who was born earlier 1957 and is not a healthcare worker wants to get the MMR vaccine before international travel. Does he demand a dose of MMR?

No, information technology is not considered necessary, just he may be vaccinated. Before implementation of the national measles vaccination plan in 1963, nigh every person acquired measles earlier adulthood. And then, this patient tin can exist considered immune based on their birth year. Nonetheless, MMR vaccine likewise may be given to any person born before 1957 who does non take a contraindication to MMR vaccination.

Routine testing of patients born before 1957 for measles-specific antibody is not recommended by CDC.

We have measles cases in our community. How can I best protect the immature children in my practice?

First of all, make certain all your patients are fully vaccinated according to the U.S. immunization schedule.

In certain circumstances, MMR is recommended for infants historic period six through 11 months. Requite infants this historic period a dose of MMR before international travel. In addition, consider measles vaccination for infants every bit young as age half-dozen months equally a command measure during a U.S. measles outbreak. Consult your state health department to find out if this is recommended in your situation. Practice non count whatsoever dose of MMR vaccine as part of the ii-dose serial if it is administered earlier a child'south showtime birthday. Instead, repeat the dose when the child is age 12 months.

In the example of a local outbreak, you also might consider vaccinating children age 12 months and older at the minimum age (12 months, instead of 12 through 15 months) and giving the second dose 4 weeks afterward (at the minimum interval) instead of waiting until age 4 through six years.

Finally, think that infants besides immature for routine vaccination and people with medical weather condition that contraindicate measles immunization depend on high MMR vaccination coverage amidst those around them. Be sure to encourage all your patients and their family members to get vaccinated if they are not immune.

During a mumps outbreak should we offer a 3rd dose of MMR (MMR Two, Merck) to persons who have ii prior documented doses of MMR?

In contempo years, mumps outbreaks have occurred primarily in populations in institutional settings with shut contact (such equally residential colleges) or in close-knit social groups. The current routine recommendation for two doses of MMR vaccine appears to exist sufficient for mumps control in the general population, but insufficient for preventing mumps outbreaks in prolonged, close-contact settings, even where coverage with 2 doses of MMR vaccine is high.

In January 2018, the Advisory Committee on Immunization Practices (ACIP) published new guidance for MMR vaccination of persons at increased gamble for acquiring mumps during an outbreak. Persons previously vaccinated with ii doses of a mumps virus�containing vaccine who are identified by public health authorities as being part of a group at increased chance for acquiring mumps because of an outbreak should receive a third dose of a mumps virus�containing vaccine to improve protection against mumps disease and related complications. More data well-nigh this recommendation is available at world wide web.cdc.gov/mmwr/volumes/67/wr/pdfs/mm6701a7-H.pdf.

In a measles outbreak, do children who take non had MMR vaccine pose a threat to vaccinated people? It is my understanding that vaccinated people can still contract measles. Am I correct?

You are correct that vaccinated people can withal be infected with viruses or bacteria against which they are vaccinated. No vaccine is 100% effective. Vaccine effectiveness varies from greater than 95% (for diseases such as measles, rubella, and hepatitis B) to much lower (threescore% for influenza in years with a adept match of circulating and vaccine viruses, and lxx% for acellular pertussis vaccines in the 3-5 years afterward vaccination). More information is available for each vaccine and affliction at www.cdc.gov/vaccines/vpd-vac/default.htm and www.immunize.org/vaccines.

Administering Vaccines Dorsum to height

Our clinic has been giving MMR past the wrong route (IM rather than SC) for years. Should these doses be repeated?

All alive injected vaccines (MMR, varicella, and yellow fever) are recommended to be given subcutaneously. Nevertheless, intramuscular administration of any of these vaccines is not likely to decrease immunogenicity, and doses given IM do not need to be repeated.

We frequently need to give MMR vaccine to large adults. Is a 25-gauge needle with a length of 5/8" sufficient for a subcutaneous injection?

Yep. A 5/viii" needle is recommended for subcutaneous injections for people of all sizes.

MMRV was mistakenly given to a 31-twelvemonth-former instead of MMR. Can this be considered a valid dose?

Yes, all the same, this result is not addressed in the 2010 MMRV ACIP recommendations. Although this is off-label use, CDC recommends that when a dose of MMRV is inadvertently given to a patient age 13 years and older, information technology may be counted towards completion of the MMR and varicella vaccine series and does not need to be repeated.

Scheduling Vaccines Back to top

How soon can nosotros requite the 2d dose of MMR vaccine to a child vaccinated at 12 months old?

For routine vaccination, children without contraindications to MMR vaccine should receive 2 doses of MMR vaccine with the first dose at historic period 12–15 months old and the second dose at age 4–6 years old. The minimum interval is 28 days for dose 2. If yous take an outbreak in your community or a child is traveling internationally, then consider using the minimum interval instead of waiting until age four–6 years former for dose 2.

Does the iv-day "grace catamenia" apply to the minimum age for administration of the get-go dose of MMR? What nigh the 28-day minimum interval between doses of MMR?

A dose of MMR vaccine administered upwardly to 4 days before the outset birthday may exist counted equally valid. However, school entry requirements in some states may mandate administration on or afterward the starting time birthday. The four-day "grace period" should not be practical to the 28-day minimum interval between two doses of a alive parenteral vaccine.

Can MMR be given on the aforementioned twenty-four hour period every bit other alive virus vaccines?

Yes. However, if 2 parenteral or intranasal live vaccines (MMR, varicella, LAIV and/or yellow fever) are not administered on the same solar day, they should exist separated by an interval of at least 28 days.

If y'all can give the second dose of MMR as early every bit 28 days after the beginning dose, why do we routinely wait until kindergarten entry to give the second dose?

The 2nd dose of MMR may be given as early as four weeks after the first dose, and be counted as a valid dose if both doses were given later the commencement altogether. The 2nd dose is non a booster, but rather it is intended to produce immunity in the small number of people who neglect to respond to the starting time dose. The risk of measles is higher in schoolhouse-age children than those of preschool age, and then it is of import to receive the second dose by school entry. It is likewise convenient to give the second dose at this age, since the child will have an immunization visit for other school entry vaccines.

What is the earliest age at which I can give MMR to an infant who will be traveling internationally? Also, which countries pose a high risk to children for contracting measles?

ACIP recommends that children who travel or live abroad should be vaccinated at an before age than that recommended for children who reside in the United States. Before their departure from the U.s.a., children age half dozen through 11 months should receive 1 dose of MMR. The take chances for measles exposure can be high in high-, middle- and low-income countries. Consequently, CDC encourages all international travelers to be up to date on their immunizations regardless of their travel destination and to keep a copy of their immunization records with them every bit they travel. For boosted information on the worldwide measles state of affairs, and on CDC's measles vaccination information for travelers, go to wwwnc.cdc.gov/travel.

If nosotros give a child a dose of MMR vaccine at vi months of historic period because they are in a community with cases of measles, when should we give the next dose?

The next dose should be given at 12 months of age. The child will also need another dose at least 28 days later. For the child to be fully vaccinated, they need to have ii doses of MMR vaccine given when the child is 12 months of age and older. A dose given at less than 12 months of age does not count as part of the MMR vaccine two-dose series.

I have an eight-calendar month-quondam patient who is traveling internationally. The baby needs to be protected from hepatitis A too as measles, mumps, and rubella. The family is leaving in xi days. Tin I give hepatitis A IG and MMR vaccine simultaneously?

No. IG may contain antibodies to measles, mumps, and rubella that could reduce the effectiveness of MMR vaccine. For this reason, in February 2018 ACIP voted to recommend that hepatitis A vaccine should be administered to infants age 6 through eleven months traveling outside the United states when protection against hepatitis A is recommended. MMR and hepatitis A vaccine may be safely co-administered to children in this age group. Neither vaccine is counted as part of the child'due south routine vaccination series. For details of this recommendation, meet the CDC ACIP recommendations for the prevention and control of hepatitis A at www.cdc.gov/mmwr/volumes/69/rr/pdfs/rr6905a1-H.pdf, folio xviii.

Can I requite the second dose of MMR before than age four through half dozen years (the kindergarten entry dose) to young children traveling to areas of the world where there are measles cases?

Yes. The 2d dose of MMR tin can exist given a minimum of 28 days afterward the first dose if necessary.

If I give MMR to an infant traveler younger than age 1 year, will that dose be considered valid for the U.S. immunization schedule?

No. A measles-containing vaccine administered more than than 4 days before the first birthday should not exist counted as part of the serial. MMR should be repeated when the child is historic period 12 through xv months (12 months if the child remains in an area where illness chance is high). The second dose should be administered at least 28 days after the kickoff dose.

Tin can I give a tuberculin skin test (TST) on the aforementioned day as a dose of MMR vaccine?

Yes. A TST tin be practical earlier or on the same twenty-four hours that MMR vaccine is given. However, if MMR vaccine is given on the previous twenty-four hours or before, the TST should be delayed for at least 28 days. Live measles vaccine given prior to the awarding of a TST tin reduce the reactivity of the skin test because of mild suppression of the allowed organisation.

An eighteen-yr-quondam college student says he had both measles and mumps diseases equally a preschooler, merely never had MMR vaccine. Is rubella vaccine recommended in such a situation?

This student should receive ii doses of MMR, separated past at least 28 days. A personal history of measles and mumps is not acceptable as proof of immunity. Acceptable evidence of measles and mumps immunity includes a positive serologic examination for antibody, birth earlier 1957, or written documentation of vaccination. For rubella, only serologic testify or documented vaccination should be accepted every bit proof of immunity. Additionally, people born prior to 1957 may be considered immune to rubella unless they are women who have the potential to become pregnant.

When not given on the same day, is the interval between yellow fever and MMR vaccines 4 weeks (28 days) or 30 days? I have seen the yellow fever and live virus vaccine recommendations published both ways.

The General Best Practice Guidelines for Immunization (encounter www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html) makes the generic recommendation that live parenterally or nasally administered vaccines non given on the same day should exist separated by at least 28 days. The CDC travel health website recommends that yellow fever vaccine and other parenteral or nasal live vaccines should exist separated by at least 30 days if possible. Either interval is adequate.

For Healthcare Personnel Back to top

What is the recommendation for MMR vaccine for healthcare personnel?

ACIP recommends that all HCP built-in during or after 1957 take acceptable presumptive show of immunity to measles, mumps, and rubella, defined equally documentation of 2 doses of measles and mumps vaccine and at least one dose of rubella vaccine, laboratory evidence of immunity, or laboratory confirmation of disease. Further, ACIP recommends that healthcare facilities should consider vaccination of all unvaccinated healthcare personnel who were built-in before 1957 and who lack laboratory show of measles, mumps, and/or rubella immunity or laboratory confirmation of disease. During an outbreak of measles or mumps, healthcare facilities should recommend two doses of MMR separated by at least 4 weeks for unvaccinated healthcare personnel regardless of birth year who lack laboratory evidence of measles or mumps amnesty or laboratory confirmation of disease. During outbreaks of rubella, healthcare facilities should recommend 1 dose of MMR for unvaccinated personnel regardless of birth twelvemonth who lack laboratory evidence of rubella immunity or laboratory confirmation of infection or illness.

Would y'all consider healthcare personnel with 2 documented doses of MMR vaccine to be allowed even if their serology for one or more than of the antigens comes back negative?

Yes. Healthcare personnel (HCP) with ii documented doses of MMR vaccine are considered to exist immune regardless of the results of a subsequent serologic examination for measles, mumps, or rubella. Documented historic period-advisable vaccination supersedes the results of subsequent serologic testing. In contrast, HCP who exercise not have documentation of MMR vaccination and whose serologic test is interpreted as "indeterminate" or "equivocal" should exist considered not immune and should receive two doses of MMR vaccine (minimum interval 28 days). ACIP does not recommend serologic testing subsequently vaccination. For more information, see ACIP'southward recommendations on the utilize of MMR vaccine at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, page 22.

If a healthcare worker develops a rash and depression-grade fever after MMR vaccine, is s/he infectious?

Approximately five to 15% of susceptible people who receive MMR vaccine volition develop a low-grade fever and/or balmy rash 7 to 12 days after vaccination. Withal, the person is not infectious, and no special precautions ( such every bit exclusion from work) need to be taken.

A 22-year-former female is going to pharmacy school and the schoolhouse wants her to accept a second dose of MMR vaccine. She had the outset dose equally a child and adult measles within 24 hours of receiving the vaccine. Recent serologic testing showed she is allowed to mumps and measles but not allowed to rubella. Can I give her a 2d dose of the MMR with her having measles afterward the first dose?

Yeah, every bit a healthcare professional person, this person should get a second dose of MMR to ensure she is immune to rubella. In that location is no harm in providing MMR to a person who is already allowed to one or more of the components. If she developed measles but i day afterward getting her first MMR, she must accept been exposed to the disease prior to vaccination.

Contraindications and Precautions Dorsum to top

What are the contraindications and precautions for MMR vaccine?

Contraindications:

• history of a severe (anaphylactic) reaction to whatever vaccine component (east.g., neomycin) or following a previous dose of MMR • pregnancy • severe immunosuppression from either illness or therapy

Precautions:

• receipt of an antibody-containing blood product in the previous 3–11 months, depending on the type of claret product received. Run across www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html, Table three-5 for more than information on this issue • moderate or severe acute illness with or without fever • history of thrombocytopenia or thrombocytopenic purpura • Important details about the contraindications and precautions for MMR vaccine are in the current MMR ACIP statement, available at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

We have many patients who are immunocompromised and cannot get the MMR vaccine. How should we advise our patients?

People with medical conditions that contraindicate measles immunization depend on loftier MMR vaccination coverage amongst those around them. To assist prevent the spread of measles virus, make sure all your staff and patients who can be vaccinated are fully vaccinated co-ordinate to the U.Due south. immunization schedule. Besides, encourage patients to remind their family unit members and other close contacts to get vaccinated if they are not allowed.

If patients who cannot get MMR vaccine are exposed to measles, CDC has guidelines for immune globulin for post-exposure prophylaxis which can exist found at world wide web.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

We have a patient who has selective IgA deficiency. We also have patients with selective IgM deficiency. Tin can MMR or varicella vaccine be administered to these patients?

In that location is no known risk associated with MMR or varicella vaccination in someone with selective IgA or IgM deficiency. Information technology is possible that the allowed response may be weaker, simply the vaccines are likely effective.

I have a patient who is traveling internationally and needs MMR vaccine. He recently received an injectable steroid. How long should he expect before receiving MMR vaccine?

There is no need to wait a specific interval before giving MMR. Injectable steroids are not considered immunosuppressive for the purpose of vaccination decisions, then at that place is no business well-nigh rubber or efficacy of MMR.

Can I give MMR to a child whose sibling is receiving chemotherapy for leukemia?

Yeah. MMR and varicella vaccines should exist given to the good for you household contacts of immunosuppressed children.

Nosotros accept a 40 lb six-year-one-time patient who has been taking 15 mg of methotrexate weekly for arthritis for 12 months. Can we give the child MMR and varicella vaccine based on this methotrexate dosage?

Based on the weight and dosage provided (twoscore lbs and fifteen mg/week), the child is currently receiving more than than 0.4 mg/kg/week of methotrexate. This meets the Infectious Disease Society of America (IDSA) definition of loftier-level immunosuppression. Administration of both varicella and MMR vaccines are contraindicated until such time every bit the methotrexate dosage can be reduced. The 2013 IDSA definition of low-level immunosuppression for methotrexate is a dosage of less than 0.4 mg/kg/week. For additional details, run into the 2013 IDSA Clinical Practise Guideline for Vaccination of the Immunocompromised Host: cid.oxfordjournals.org/content/early/2013/11/26/cid.cit684.total.pdf.

Is it true that egg allergy is not considered a contraindication to MMR vaccine?

Several studies have documented the safety of measles and mumps vaccine (which are grown in chick embryo tissue culture) in children with astringent egg allergy. Neither the American Academy of Pediatrics nor ACIP consider egg allergy every bit a contraindication to MMR vaccine. ACIP recommends routine vaccination of egg-allergic children without the use of special protocols or desensitization procedures.

Tin can I requite MMR to a breastfeeding mother or to a breastfed baby?

Yeah. Breastfeeding does not interfere with the response to MMR vaccine. Vaccination of a woman who is breastfeeding poses no risk to the baby being breastfed. Although information technology is believed that rubella vaccine virus, in rare instances, may be transmitted via chest milk, the infection in the babe is asymptomatic.

If a patient recently received a blood product, can he or she receive MMR vaccine?

Yes, but there should be sufficient fourth dimension between the blood production and the MMR to reduce the run a risk of interference. The interval depends on the blood product received. See Tabular array 3-5 of ACIP's General Best Practice Guidelines for Immunization for more information, bachelor at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.

Is it adequate practice to administer MMR, Tdap, and influenza vaccines to a postpartum mom at the same time as administering RhoGam?

Yes. Receipt of RhoGam is not a reason to delay vaccination. For more information run across the ACIP General Best Practice Guidelines for Immunization, bachelor at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.

Please describe the electric current ACIP recommendations for the utilise of MMR vaccine in people who are infected with HIV.

ACIP recommendations for vaccinating people with HIV infection were revised in 2013. The current recommendations are equally follows:

Administer two doses of MMR vaccine to all HIV-infected people age 12 months and older who do not take evidence of current severe immunosuppression or current evidence of measles, rubella, and mumps immunity. To be regarded as not having prove of electric current severe immunosuppression, a child age 5 years or younger must have CD4 percentages of 15% or more for vi months or longer; a person older than 5 years must accept CD4 percentages of 15% or more and a CD4 lymphocyte count of 200 or more/mm3 for vi months or longer. If laboratory results country only i type of parameter (per centum or counts) this is sufficient for vaccine decision-making.

Administer the offset dose at 12 through xv months and the second dose to children age 4 through 6 years, or as early on as 28 days after the kickoff dose.

Unless they have adequate current testify of measles, mumps, and rubella amnesty, people with perinatal HIV infection who were vaccinated prior to establishment of effective antiretroviral therapy (ART) should receive two appropriately spaced doses of MMR vaccine afterwards effective ART has been established. Established effective ART is defined as receiving ART for at to the lowest degree six months in combination with CD4 percentages of 15% or more for vi months or longer for children age 5 years or younger. People older than 5 years should have CD4 percentages of fifteen% or more and a CD4 lymphocyte count of 200 or more/mm3 for vi months or longer. If laboratory results state only i type of parameter (percentages or counts) this is sufficient for vaccine decision-making.

Pregnancy and Postpartum Considerations Back to top

What is the recommended length of time a adult female should wait after receiving rubella (MMR) vaccine before becoming pregnant?

Although the MMR vaccine packet insert recommends a three-month deferral of pregnancy after MMR vaccination, ACIP recommends deferral of pregnancy for 4 weeks. For details on this issue, see ACIP'due south Control and Prevention of Rubella: Evaluation and Direction of Suspected Outbreaks, Rubella in Significant Women, and Surveillance for Congenital Rubella Syndrome.

How should teenage girls and women of child-bearing age be screened for pregnancy before MMR vaccination?

ACIP recommends that women of childbearing age be asked if they are currently pregnant or attempting to become pregnant. Vaccination should be deferred for those who respond "yes." Those who answer "no" should exist advised to avoid pregnancy for four weeks post-obit vaccination. Pregnancy testing is not necessary.

If a pregnant woman inadvertently receives MMR vaccine, how should she exist brash?

No specific activity needs to be taken other than to reassure the woman that no adverse outcomes are expected as a result of this vaccination. MMR vaccination during pregnancy is not a reason to terminate the pregnancy. You should consult with others in your healthcare setting to identify ways to forestall such vaccination errors in the future. Detailed information almost MMR vaccination in pregnancy is included in the most recent MMR ACIP statement, bachelor at world wide web.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

We crave a pregnancy test for all our 7th graders before giving an MMR. Is this necessary?

No. ACIP recommends that women of childbearing historic period exist asked if they are currently pregnant or attempting to become meaning. Vaccination should be deferred for those who reply "yes." Those who answer "no" should be brash to avoid pregnancy for i calendar month post-obit vaccination.

Tin we give an MMR to a xv-month-sometime whose female parent is 2 months meaning?

Yes. Measles, mumps, and rubella vaccine viruses are not transmitted from the vaccinated person, so MMR vaccination of a household contact does not pose a risk to a pregnant household member.

If a woman'due south rubella test result shows she is "non immune" during a prenatal visit, but she has 2 documented doses of MMR vaccine, does she need a third dose of MMR vaccine postpartum?

In 2013, ACIP changed its recommendation for this state of affairs (encounter www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, pages 18–20). It is recommended that women of childbearing historic period who have received 1 or 2 doses of rubella-containing vaccine and have rubella serum IgG levels that are not clearly positive should be administered 1 boosted dose of MMR vaccine (maximum of iii doses) and do non need to be retested for serologic bear witness of rubella immunity. MMR should non be administered to a pregnant adult female.

I have a female patient who has a non-allowed rubella titer two months afterward her second MMR vaccination. Should she be revaccinated? If so, should the titer again be checked to determine seroconversion?

ACIP recommends that vaccinated women of childbearing age who have received one or two doses of rubella-containing vaccine and have a rubella serum IgG levels that is not clearly positive should be administered ane additional dose of MMR vaccine (maximum of three doses). Repeat serologic testing for evidence of rubella immunity is non recommended. Meet www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, pages 18–20, for more data on this issue.

MMR vaccines should not be administered to women known to be pregnant or attempting to become pregnant. Because of the theoretical risk to the fetus when the mother receives a alive virus vaccine, women should be counseled to avoid condign pregnant for 28 days after receipt of MMR vaccine.

How soon afterward delivery can MMR be given to the female parent?

MMR can be administered any time afterward delivery. The vaccine should be administered to a woman who is susceptible to either measles, mumps, or rubella before infirmary discharge, even if she has received RhoGam during the hospital stay, leaves in less than 24 hours, or is breastfeeding.

Vaccine Condom Dorsum to pinnacle

Is there any evidence that MMR or thimerosal causes autism?

No. This consequence has been studied extensively, including a thorough review by the contained Institute of Medicine (IOM). The IOM issued a written report in 2004 that concluded there is no evidence supporting an association between MMR vaccine or thimerosal-containing vaccines and the development of autism. For more than information on thimerosal and vaccines in general, visit www.cdc.gov/vaccinesafety/Concerns/thimerosal/index.html.

A few parents are asking that their children receive separate components of the MMR vaccine considering they fear MMR may be linked to autism. What should I exercise?

Merck no longer produces single antigen measles, mumps, and/or rubella vaccines for the U.S. market. Only combined MMR is available. You should educate parents about the lack of clan between MMR and autism.

How likely is it for a person to develop arthritis from rubella vaccine?

Arthralgia (articulation pain) and transient arthritis (joint redness or swelling) following rubella vaccination occurs only in people who were susceptible to rubella at the time of vaccination. Joint symptoms are uncommon in children and in adult males. About 25% of non-immune post-pubertal women report joint pain after receiving rubella vaccine, and most 10% to 30% study arthritis-like signs and symptoms.

When articulation symptoms occur, they mostly brainstorm 1 to 3 weeks after vaccination, ordinarily are mild and non incapacitating, last virtually 2 days, and rarely recur.

Is at that place whatsoever harm in giving an extra dose of MMR to a kid of historic period seven years whose record is lost and the mother is not sure about the final dose of MMR?

In full general, although it is not ideal, receiving extra doses of vaccine poses no medical problem. Nevertheless, receiving excessive doses of tetanus toxoid (e.g., DTaP, DT, Tdap, or Td) can increase the adventure of a local adverse reaction. For details see the Actress Doses of Vaccine Antigens section of the ACIP General Best Practice Guidelines for Immunization at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.

Vaccination providers oft run across people who do not have adequate documentation of vaccinations. Providers should only accept written, dated records as evidence of vaccination. With the exception of influenza vaccine and pneumococcal polysaccharide vaccine, cocky-reported doses of vaccine without written documentation should not exist accepted. An attempt to locate missing records should exist fabricated whenever possible past contacting previous healthcare providers, reviewing state or local immunization data systems, and searching for a personally held tape.

If records cannot be located or will definitely not be bachelor anywhere because of the patient's circumstances, children without adequate documentation should be considered susceptible and should receive age-appropriate vaccination. Serologic testing for immunity is an alternative to vaccination for certain antigens (e.one thousand., measles, rubella, hepatitis A, diphtheria, and tetanus).

Storage and Treatment Back to pinnacle

How long can reconstituted MMR vaccine be stored in a fridge before information technology must be discarded?

The amount of time in which a dose of vaccine must be used after reconstitution varies by vaccine and is normally outlined somewhere in the vaccine'south package insert. MMR must be used inside viii hours of reconstitution. MMRV must be used inside 30 minutes; other vaccines must exist used immediately. The Immunization Action Coalition has a staff pedagogy piece that outlines the time allowed betwixt reconstitution and utilize, as stated in the package inserts for a number of vaccines. Handout tin can be found at the following link: www.immunize.org/catg.d/p3040.pdf.

How should MMR vaccine be stored?

MMR may be stored either in the fridge at ii°C to eight°C (36°F to 46°F) or in the freezer at -50°C to -15°C (-58°F to +5°F). The diluent should not be frozen and can be stored in the refrigerator or at room temperature.

If the MMR is combined with varicella vaccine every bit MMRV (ProQuad, Merck), it must exist stored in the freezer at -50°C to -xv°C (-58°F to +v°F).

A box of MMR vaccine (not reconstituted) was left at room temperature overnight. Can I use it?

Unfortunately, serious errors in vaccine storage and handling like this occur too ofttimes. If you suspect that vaccine has been mishandled, you should store the vaccine as recommended, and then contact the manufacturer or land/local health department for guidance on its utilise. This is particularly of import for live virus vaccines like MMR and varicella.

Once MMR vaccine has been reconstituted with diluent, how shortly must it be used?

It is preferable to administer MMR immediately after reconstitution. If reconstituted MMR is not used within viii hours, it must be discarded. MMR should always exist refrigerated and should never be left at room temperature.

I misplaced the diluent for the MMR dose and then I used normal saline instead. Is there any problem with doing this?

Only the diluent supplied with the vaccine should be used to reconstitute any vaccine. Any vaccine reconstituted with the incorrect diluent should be repeated.
