MMR vaccine side-effects
(Measles, Mumps, and Rubella)
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 measles, mumps or rubella.
Most people who get MMR vaccine do not have any serious 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 (about 1 person out of 75)
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 reported after a child gets
MMR vaccine, including:
◦Deafness
◦Long-term seizures, coma, or lowered consciousness
◦Permanent brain damage
These are so rare that it is hard to tell whether they are caused by the
vaccine.
