IFN-α armed gE elicits superior immunogenicity compared to unmodified antigens and flagellin armed gE in mice.

ABSTRACT: Herpes zoster (HZ) induces significant pain and discomfort, which can seriously affect the quality of life of patients. At present, there is no specific treatment for HZ, and the mosteffective HZ control is vaccination. The main obstacle to developing an effective HZ vaccine is poorly induced cellular immune response. In this study, the IFN-α-gE-Fc fusion protein induced higher levels of humoral and cellular immunity compared to the unengineered gE antigen and higher levels of cellular immunity compared to the flagellin-gE-Fc fusion protein in a murine model. Compared with the marketed recombinant herpes zoster vaccine (Shingrix), IFN-α-gE-Fc can replace current used MPL adjuvant. At the same time, the immunogenicity of the IFN-α-gE-Fc + AQ was not weaker than that of the marketed recombin
