First question to ask when MAS posts a "Drive By" video...""What is he not telling us?"...
Check out the attached article from Bloomberg...btw, the vast majority of doses administered in the U.S. have been the Pfizer and Moderna vaccines, which require 2 doses for full vaccination....since ~165M Americans are fully vaccinated, the 350M doses administered number is very reasonable when adding in the one dose J&J vaccine.
