SARS-CoV-2 Spike glycoprotein (Ad26.COV2-S)

SARS-CoV-2 Spike glycoprotein (Ad26.COV2-S) is a monovalent vaccine composed of a recombinant, replicationincompetent human adenovirus type 26 vector that encodes a SARS-CoV-2 full-length spike (S) glycoprotein in a stabilised conformation. Following administration, the S glycoprotein of SARSCoV-2 is transiently expressed, stimulating both neutralising and other functional S-specific antibodies, as well as cellular immune responses directed against the S antigen, which may contribute to protection against COVID-19.
