Measles, Mumps, and Rubella Vaccines (patient information)

Why get vaccinated?
Measles, mumps, and rubella are serious diseases.

Measles:

Measles virus causes rash, cough, runny nose, eye irritation, and fever. It can lead to ear infection, pneumonia, seizures (jerking and staring), brain damage, and death.

Mumps:

Mumps virus causes fever, headache, and swollen glands. It can lead to deafness, meningitis (infection of the brain and spinal cord covering), painful swelling of the testicles or ovaries, and, rarely, death.

Rubella (German Measles):

Rubella virus causes rash, mild fever, and arthritis (mostly in women). If a woman gets rubella while she is pregnant, she could have a miscarriage or her baby could be born with serious birth defects.

You or your child could catch these diseases by being around someone who has them. They spread from person to person through the air. Measles, mumps, and rubella (MMR) vaccine can prevent these diseases. Most children who get their MMR shots will not get these diseases. Many more children would get them if we stopped vaccinating.

Who should get MMR vaccine and when?
Children should get 2 doses of MMR vaccine:


 * The first at 12-15 months of age.
 * The second at 4-6 years of age.

These are the recommended ages. But children can get the second dose at any age, as long as it is at least 28 days after the first dose.

Some adults should also get MMR vaccine. Generally, anyone 18 years of age or older, who was born after 1956, should get at least one dose of MMR vaccine, unless they can show that they have had either the vaccines or the diseases. Ask your doctor or nurse for more information. MMR vaccine may be given at the same time as other vaccines.

Who should not get MMR vaccine or should wait?
People should not get MMR vaccine who have ever had a life-threatening allergic reaction to gelatin, the antibiotic neomycin, or to a previous dose of MMR vaccine. People who are moderately or severely ill at the time the shot is scheduled should usually wait until they recover before getting MMR vaccine. Pregnant women should wait to get MMR vaccine until after they have given birth. Women should avoid getting pregnant for 4 weeks after getting MMR vaccine.

Some people should check with their doctor about whether they should get MMR vaccine, including anyone who:


 * Has HIV/AIDS, or another disease that affects the immune system
 * Is being treated with drugs that affect the immune system, such as steroids, for 2 weeks or longer
 * Has any kind of cancer
 * Is taking cancer treatment with x-rays or drugs
 * Has ever had a low platelet count (a blood disorder)

People who recently had a transfusion or were given other blood products should ask their doctor when they may get MMR vaccine.

Ask your doctor or nurse for more information.

What are the risks from MMR vaccine?
A vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of MMR vaccine causing serious harm, or death, is extremely small. Getting MMR vaccine is much safer than getting any of these three diseases. Most people who get MMR vaccine do not have any problems with it.

Mild problems:


 * Fever (up to 1 person out of 6)
 * Mild rash (about 1 person out of 20)
 * Swelling of glands in the cheeks or neck (rare)
 * If these problems occur, it is usually within 7-12 days after the shot. They occur less often after the second dose.

Moderate Problems:


 * Seizure (jerking or staring) caused by fever (about 1 out of 3,000 doses)
 * Temporary pain and stiffness in the joints, mostly in teenage or adult women (up to 1 out of 4)
 * Temporary low platelet count, which can cause a bleeding disorder (about 1 out of 30,000 doses)

Severe Problems (Very Rare):


 * Serious allergic reaction (less than 1 out of a million doses)
 * Several other severe problems have been known to occur after a child gets MMR vaccine. But this happens so rarely, experts cannot be sure whether they are caused by the vaccine or not. These include: deafness; long-term seizures, coma, or lowered consciousness; permanent brain damage.

What if there is a moderate or severe reaction?
What should I look for?

Any unusual conditions, such as a serious allergic reaction, high fever or behavior changes. Signs of a serious allergic reaction include difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, a fast heart beat or dizziness within a few minutes to a few hours after the shot. A high fever or seizure, if it occurs, would happen 1 or 2 weeks after the shot.

What should I do?
 * Call a doctor, or get the person to a doctor right away.
 * Tell your doctor what happened, the date and time it happened, and when the vaccination was given.
 * Ask your health care provider to file a Vaccine Adverse Event Reporting System (VAERS) form if you have any reaction to the vaccine. Or call VAERS yourself at 1-800-822-7967, or visit their website at http://vaers.hhs.gov.

The National Vaccine Injury Compensation Program
In the rare event that you or your child has a serious reaction to a vaccine, a federal program has been created to help pay for the care of those who have been harmed.

How can I learn more?

 * Ask your doctor or other health care provider. They can give you the vaccine package insert or suggest other sources of information.
 * Call your local or state health department's immunization program.
