The “waning” effectiveness of the Covid boosters appears to be just a statistical illusion created by not counting infections within a 7-14 day window after getting a booster shot. Professor Vinay Prasad wrote “Many observational studies of vaccine effectiveness exclude cases that occurred within 14 days of dose … Omitting these cases is irresponsible … this can make an inactive product— something totally useless— look like it works.” Norman Fenton has shown that “any claims of Covid-19 vaccine efficacy based on these studies are likely to be a statistical illusion.”
