Mechanism of action

MMRV combines the Merck MMRII (measles, mumps, rubella) vaccine with the Varivax (varicella) vaccine into a single formulation. Each component contains live attenuated virus strains that replicate in vaccinated individuals, triggering both humoral and cellular immune responses without causing disease. This provides protection against all four viral infections with a single injection.
