Viral antigen from Measles virus, Mumps virus, Rubella virus, or Varicella-zoster virus

Viral antigens from Measles virus, Mumps virus, Rubella virus, and Varicella-zoster virus are immunogenic proteins present in these four distinct viruses. They are the targets recognized by the host immune system during infection and after vaccination, leading to the production of specific antibodies and cellular immune responses. Measurement of immunity to these viral infections generally relies on the detection of IgG antibodies directed against these antigens. These antigens form the basis of live attenuated vaccines (MMR and MMRV), which provide long-lasting protection against the respective diseases. This entry improperly combines four unrelated viral antigens, which should each be listed separately for molecular specificity[1][5][9].
