Nearly all children who get the MMR vaccine (more than 80%) will have no side effects.
Most children who have a side effect will have only a mild reaction: soreness, redness or swelling where the shot was given, mild rash, mild to moderate fever, swelling of the lymph glands, and temporary pain, stiffness, or temporary swelling in the joints.In about 5% to 15% fever may be present 7-12 days after.
