Protective Efficacy of Lyophilized Vesicular Stomatitis Virus-Based Vaccines in Animal Model

Emerg Infect Dis. 2024 May;30(5):1004-1008. doi: 10.3201/eid3005.231248.

Abstract

We evaluated the in vitro effects of lyophilization for 2 vesicular stomatitis virus-based vaccines by using 3 stabilizing formulations and demonstrated protective immunity of lyophilized/reconstituted vaccine in guinea pigs. Lyophilization increased stability of the vaccines, but specific vesicular stomatitis virus-based vaccines will each require extensive analysis to optimize stabilizing formulations.

Keywords: Ebola virus; Lassa virus; animal models; glycoproteins; guinea pigs; lyophilized; vaccines; vesicular stomatitis virus; viruses; zoonoses.
