But these were total numbers. The study also broke down efficacy over the 14 to 120 day period after vaccination, as well as after the 120 day mark, also known as VE. This is where the numbers differed most significantly.

The Moderna vaccine was 92% effective against hospitalization after 120 days, but the Pfizer vaccine was less than 77% effective. (There was no similar tally for the J&J vaccine, although the CDC notes that efficacy peaked at 68% after 28 days of vaccination.)
