Your Vaccine Booster Calculator [View all]

According to the latest Pfizer trial, efficacy peaked at 96.2% during the interval from 7 days to less than two months post-dose #2, and declined gradually to 83.7% from 4 months post-dose #2 to the end of the trial, an average decline of about 6% every two months.

One could assume a continued decline in efficacy of ABOUT 6% every two months going forward from your second shot, and that the Moderna vaccine is likely quite similar.

Bring on the boosters!
