However, whether the vaccine is really “variant proof” or merely less affected by emerging variants remains to be seen. Unlike the Pfizer and Moderna shots, the J&J vaccine use a cold virus, called an adenovirus, to carry the spike gene into the body. As VLA2001 is a whole inactivated virus vaccine, it induced antigen-specific T-cell responses towards the SARS-CoV-2 spike, membrane, and nucleocapsid proteins, as opposed to just the spike protein as with the currently deployed vaccines. This means the vaccine is more likely to be effective against the type of virus variants we’ve already seen emerging, and may emerge in the future. 2021.
