On February 5, 2021, President Biden tweeted, “Here’s the deal: Unvaccinated individuals are 97 times more likely to die compared to those who are boosted.” This claim—which Biden did not support but seems to be a gross distortion of a bogus statistic from CDC director Rochelle Walensky—clashes with the most objective, relevant, and important evidence on this matter.

That evidence consists of two large RCTs for the Pfizer and Moderna vaccines, which were the FDA’s main basis for approving them. These studies involved 72,663 generally healthy adults and older children in the pre-Delta/Omicron era who didn’t yet have naturally acquired immunity to C-19. After half of the subjects were randomly given a vaccine and the other half a placebo, 37 people died who received a vaccine, and 33 died who received a placebo.

On a superficial basis, these figures suggest that the vaccines increased the relative risk of death by 13%. However, the death rate in both groups was so small (0.1%) that the difference between them is statistically insignificant. More specifically, the results demonstrate with 95% confidence that:

  • neither of the vaccines decreased or increased the absolute risk of death by any more than 0.08%.
  • the vaccines could prevent up to two deaths or cause up to three deaths per year among every 1,000 people.

In short, the strongest available evidence shows no indication that the mRNA Covid vaccines save more lives than they take. However, the benefits and risks of the vaccines can vary greatly for each individual.
