Abstract: The invention generally relates to the development of immunogenic compositions comprising a DNA copy of at least one live attenuated plus-sense single-stranded RNA virus genome, such as the genome of a live-attenuated Zika vims (ZIKV), Japanese encephalitis virus (JEV) or yellow fever vims (YFV). The immunogenic compositions can be used for treating or conferring protective immunity against diseases related to plus-sense single-stranded RNA viruses, e.g. for affording prolonged immunoprotection against such viruses and protective immunity is conferred at low diseases, e.g., as low as 300 or 500 ng after administration of a single pLAV dosage.

Abstract: This composition of this invention is comprised of live attenuated SARS-CoV-2 constructs as vaccines or research tools. Described herein is a highly attenuated SARS-CoV-2 with deleted accessory proteins and modified transcriptional regulator sequences (TRS) that can serve as a live-attenuated vaccine platform and a BSL-2 experimental system. Certain embodiments are directed to a live attenuated SARS-CoV-2 having a modified transcriptional regulatory sequence (TRS) and a deletion of one or more open reading frames selected from ORF3a, ORF3, ORF6, ORF7, and/or ORFS.

Abstract: The present invention discloses a live attenuated strain of Zika virus (ZIKV) having a deletion in the 3? untranslated region (3?UTR) of the viral genome, which may affect viral RNA synthesis and sensitivity to type I interferon inhibition, but may not affect viral RNA translation. The present invention also discloses the use of these live attenuated ZIKV strains in the preparation of ZIKV vaccines and for providing immunoprotection against ZIKV infection and congenital ZIKV syndrome, particularly in pregnant females.
