ABSTRACT -
Amezosvatein (CRV-101) is an investigational non-mRNA, adjuvanted recombinant subunit vaccine candidate for prevention of herpes zoster caused by varicella-zoster virus. The vaccine uses varicella-zoster virus glycoprotein E (gE) antigen with a synthetic adjuvant system designed to activate immune responses, including TLR4-pathway stimulation. It is a biologic vaccine product and does not have a single small-molecule skeletal structure.
