Phase 1 Trial of ChAd68 and Ad5 Adenovirus COVID-19 Vaccines Delivered by Aerosol

Ad5-triCoV/Mac is a recombinant type 5 human adenovirus vector which has been engineered to express our trivalent SARS-CoV-2 transgene cassette under the control of an MCMV promoter, and is followed by an SV40 polyA signal. The adenovirus construct is E1 and E3 deleted.This trivalent transgene cassette consists of the S1 region of SARS-CoV-2 spike protein (aa 47-716), full-length SARS-CoV-2 nucleoprotein (N) fused to a highly conserved portion of the SARS-CoV-2 polymerase (RdRp or POL).

ChAd-triCoV/Mac is an E1 and E3 deleted chimpanzee adenovirus serotype 68 where the trivalent SARS-CoV-2 transgene cassette is under the control of an HCMV promoter and is followed by an SV40 polyA signal. The trivalent transgene cassette consists of the S1 region of SARS-CoV-2 spike protein (aa 47-716), full-length SARS-CoV-2 nucleoprotein (N) fused to a highly conserved portion of the SARS-CoV-2 polymerase (RdRp or POL).
