Pfizer vaccine shows it doesn't reduce overall deaths.

A cynic would said that you can "massage the data" or throw in artifacts  or  obfuscate or just plain prevaricate  in ways

that will give you the answer you wish to reach. I trust only what I have personally observed in my family & friends. No one 

fully vaxed died, some who were vaxed got cases that did not require hospitalization, but everyone I personally know who

succumbed was not vaxed. Twitter, by its very nature, is too brief to be relied upon for anything but entertainment or as 

an idea to spur for real research.
