How can Pfizer or Moderna give accurate accounts of people not catching covid 19 because of their drug when all 43,000 trial patients have to wear masks and social distance like we do? After all according to Dr. Fauci a mask is as good as a vaccine.

Now if these 43,000 didn't wear a mask or social distance then the numbers would be more reliable and I'm sure the shot wouldn't be anywhere near 95% effective.

I'm sure this years flu shot will be more effective also.
