Also, the vaccine is just about effective as PFZ and MOD when you look at illness requiring hospitalization or causing death.
Also, PFZ and MOD weren't tested against some of the new variants which are more resistant, like J&J was. It's possible that PFZ and MOD are really just as effective as J&J.
Any vaccine over 50% effective can lead to the R-nought dropping to below 1.0, which is the path to herd immunity.
Actually I saw where PFZ was tested and shown to be at least somewhat effective against the South Africa strain.
