People who have severe allergies to eggs are more likely to have an increased risk of allergic reactions to the measles, mumps, and rubella vaccine. However, it is extremely rare that the measles, mumps, and rubella vaccine will cause serious harm or death. Moreover, getting the measles, mumps, and rubella vaccine is much safer than getting measles, mumps or rubella. Few people who get the vaccine have serious problems with it.

People who have had severe reactions to neomycin should not receive the measles, mumps, and rubella vaccine because neomycin is used in the vaccine manufacturing process.

People with low blood platelets (thrombocytopenia) may develop more severe thrombocytopenia following vaccination.


Mild side effects of the measles, mumps, and rubella vaccine include:

  • Fever
  • Mild rash
  • Swelling of the glands in the cheeks or neck
  • Other potential side effects that have been reported after taking the measles, mumps, and rubella vaccine include:
  • Seizures caused by fever
  • Temporary pain and stiffness in the joints
  • Temporary low platelet count that may cause bleeding problems
  • Serious allergic reaction
  • Deafness
  • Long-term seizures, coma, or lowered consciousness
