Effect of sequential vaccination with recombinant vesicular stomatitis virus (VSV)–based vaccines on protective efficacy afforded by each vaccine in nonhuman primates. Vaccination with a VSV-based Lassa virus vaccine encoding the Lassa virus glycoproteins provides complete and possibly sterile immunity against a lethal Lassa virus (LASV) challenge. Approximately 90 days after receiving the initial VSV–Lassa vaccine, animals were vaccinated with a VSV-based Ebola virus (EBOV) vaccine. Although we

Approximately 90 days after receiving the initial VSV–Lassa vaccine, animals were vaccinated with a VSV-based Ebola virus (EBOV) vaccine. Although we observed a robust VSV-specific immune response, the VSV–Ebola virus vaccine provided complete and possibly sterile immunity against a lethal Zaire Ebola virus challenge.
