The COVID-19 vaccine was tested too rapidly and the clinical trials, which demonstrated its extreme efficacy in creating immunity, did not have sufficient granularity to assess its safety in certain subsets of the population.
Again, as a cellular immunologist, my thinking about the safety of this vaccine does not operate in generalities. Rather, I ask: what specific subset or subsets of people are at risk of harm — and have our clinical trials established safety in such subsets?
As you know, I do not believe that the COVID-19 vaccines have been adequately tested for safety in a VERY SPECIFIC subset of persons — daily growing in numbers. I have prognosticated and warned the FDA, CDC, Pfizer and Moderna, that a potentially severe hazard exists in the indiscriminate deployment of the COVID-19 vaccine in the midst of this outbreak. My safety concern, inadequately addressed by the clinical trials, is whether vaccination of those persons with recent or occult SARS-CoV-2 infection is hazardous.
