Mechanism of action

The vaccine contains recombinant varicella-zoster virus (VZV) glycoprotein E (gE) combined with an adjuvant system (AS01B) that enhances immune response. This approach triggers both cellular and humoral immunity against VZV without the risks associated with live attenuated vaccines, providing durable protection against herpes zoster and post-herpetic neuralgia in older adults and immunocompromised populations.
