Shielding Replicating Single-cycle Vaccines against SARS-CoV-2

NIH Pandemic-Era Grants · Pandemic Era Grants / 2023

Michael A Barry · MAYO CLINIC ROCHESTER · 2023 · $470,627 — Abstract Many COVID-19 vaccines are replication-defective mRNA, DNA, or adenovirus (Ad) vaccines. In each case, the vaccine delivers its one copy of an antigen gene and expresses "1X" of the antigens that are encoded by the vaccine. We developed single cycle Ad (SC-Ad) vaccines that replicate vaccin…

RNA Recombination in Coronaviruses

NIH Pandemic-Era Grants · Pandemic Era Grants / 2023

Andrew Laurence Routh · SCRIPPS RESEARCH INSTITUTE, THE · 2023 · $398,043 — RNA viruses are exceptionally diverse and rapidly evolving. Their RNA-dependent RNA polymerases are prone to mutation, lack proof-reading capabilities (with the unique exception of coronaviruses) and frequently undergo recombination between both homologous and non-homologous templates. This confers …
