Mechanism of action

The vaccine contains live but weakened (attenuated) strains of measles, mumps, and rubella viruses. When administered, these attenuated viruses replicate in the body at low levels, triggering both humoral (antibody) and cell-mediated immune responses without causing disease. This generates protective immunity against natural infection with these three viruses.
