Given exponential growth of the virus, and the very large changes to society made to avoid virus population growth I think the NNT isn’t an effective measurement tool. Clearly the value of the vaccine depends heavily on where/when you are.
Additionally, if the virus has an R greater than 1, preventing one person from being infected has a larger impact on total infected population.
- sanxiyn 6y agoThat's the point. Pfizer's trial does not evaluate reduction of R or "preventing one person from being infected". It would have been better if it did, but it does not. NNT is a natural way to measure the result of this trial since the result is about prevention of disease, NOT prevention of infection.
