The following is supposedly a summary of the data for the Pfizer trials. Can someone verify? If true these are not statistically significant results and their executives should be held to account for disingenuous efficacy claims
We're being assured by Pfizer and Moderna that their Covid vaccines are 95% effective and are safe enough to be injected into hundreds of millions of people. Before accepting these extremely consequential claims, let's look at the actual testing process and results.
In the Pfizer trial, half of the 44,000 volunteers received the vaccine and the other half got a placebo shot. Then the researchers waited around to see how many of the volunteers randomly came down with Covid. Pfizer reported that out of 170 cases of Covid, 162 were in the placebo group and eight were in the vaccine group.
So a total of 0.386% of the 44,000 volunteers came down with Covid by means unknown, and this tiny sample is the foundation of grandiose claims of 95% effectiveness? Note the incredibly small sample size. If even 3% of the test group had contracted Covid, the sample size would be 1,320 people--still a small number but considerably more persuasive than 1/3rd of 1% (170).
