More Information
Summary:The present invention provides a replication incompetent HSV-1 viral vaccine comprising a modified genome of HSV-1 and at least one antigen. The modification comprises a deletion of internal repeats, an inactivating mutation in ICP47 and an inactivating mutation in the other copy of ICP4. A first antigen of the at least one antigen is driven by a promoter of an immediate early gene, such as ICP4. In a specific example, the HSV-1 viral vaccine expresses antigens from SARS-Cov, SARS-Cov-2 and variants thereof and is used for inducing immune responses against sarbecoviruses in a subject to which the vaccine is administered.
