Ruling: FALSE.

Available data from ongoing phase 3 clinical trials do not demonstrate these claimed benefits. Berkshire Vaccination Collaborative is spreading #VaccineMisinformation.

2/7

Risk of hospitalization was not a primary endpoint measured in the study. In a post hoc analysis, there were 2 hospitalizations in the vaccine group two weeks after vaccination, falsifying the claim that it is 100% effective at preventing hospitalization.

3/7

After 28 days since vaccination, there were no COVID-19-related hospitalizations in the vaccinated group compared to 5 central-laboratory-confirmed cases in the placebo group (7 including non-confirmed cases).

4/7

The number of centrally confirmed cases is too small to draw firm conclusions as the differences between vaccinated and unvaccinated groups is not statistically significant.

5/7

Based on the post hoc analysis including non-centrally confirmed cases, the FDA considers reduction in the risk of hospitalization to be a demonstrated benefit, but it does not recognize protection against death to be a demonstrated benefit.

6/7

On the contrary, as the FDA notes, "A larger number of individuals at high risk of COVID-19 and higher attack rates would be needed to confirm efficacy of the vaccine against mortality." This falsifies Berkshire Vaccination Collaborative's claim.
