Efficacy Of Covid Vaccines - Absolute Risk Reduction = About 1%

[Scott777]

According to the Lancet, the Absolute Risk Reduction (i.e., if you take the vaccines, how much does it reduce the risk of catching Covid, compared to someone without the vaccine):

Astra Zeneca: 1.3%
Pfizer:            0.84%

Good luck with that shite.  🤮

ARR - what it means.

Given 100 people with Covid, if the percentage of them who get mild to moderate illness is 50%, then the vaccine (ARR 1%) reduces the 50% by 1% to 49%.  So only 49 would get mild to moderate illness.  The study does not seem to look at more severe cases.
