Mechanism of action

The vaccine contains live attenuated varicella-zoster virus that triggers both cellular and humoral immune responses, priming T cells and B cells to recognize and eliminate the virus if exposure occurs. This prevents herpes zoster (shingles) and its complications in vaccinated individuals, particularly those at higher risk due to age or immunocompromise.
