Mechanism of action

The vaccine contains weakened (attenuated) strains of measles, mumps, and rubella viruses that replicate in the body without causing disease. This replication triggers both humoral (antibody) and cell-mediated immune responses, providing long-term protection against infection with wild-type viruses. The vaccine is typically administered as two doses to achieve optimal immunity.
