What are the risks and side effects of the MMR vaccine?

For most adults, the benefits of the MMR vaccine outweigh the risks. A few people develop a short-term mild rash, fever, swollen glands, or pain and stiffness in the joints after getting the shot. More serious, and rare, side effects include a temporary low platelet count or serious allergic reaction.

Call your doctor if you have trouble breathing, dizziness, rapid heartbeat, hives, weakness, or other problems after vaccination.
