How It Works
This medicine contains live attenuated varicella-zoster virus that replicates in the host, inducing both humoral and cell-mediated immune responses. The attenuated virus is unable to cause clinical disease in immunocompetent individuals but stimulates production of specific antibodies and T-lymphocytes that provide protection against future wild-type virus infection.
