Mechanism of action

The vaccine contains weakened (attenuated) strains of measles, mumps, and rubella viruses that replicate in the body without causing disease, triggering both humoral and cellular immune responses. This results in the production of protective antibodies and memory immune cells that prevent infection if exposed to wild-type viruses in the future.
