Mechanism of action

The vaccine contains weakened (attenuated) strains of measles, mumps, and rubella viruses that replicate in vaccinated individuals but do not cause disease. This triggers both humoral (antibody) and cell-mediated immune responses, providing long-term protective immunity against these three viral infections. Upon exposure to wild-type virus, the primed immune system rapidly produces neutralizing antibodies and activates T cells to prevent infection or severe disease.
