COVID-19 Vaccine From Pfizer … 90% Efficacy … BUT, Did Both Test Groups Have Same Exposure To Virus?
Something about these results continue to nag me. I can’t find a statement as to how the WHOLE 43,538 sample was SUBJECTED to the same level of COVID exposure.
What keeps NAGGING at me. What if the PLACEBO GROUP had MORE exposure to COVID infection than the ‘vaccinated’ group. I just can’t, at first read, get an idea as to how the whole sample was exposed to infection.
Do you get what I am getting at?
If the level of EXPOSURE was different — or worse still RANDOM — in my eyes this means diddly (& I do have some background in data analysis).
I could be wrong.
I am not CONVINCED.
I always want FACTS & PROOF. That is my training, background & druthers. SMILE.
PLEASE help me IF you can? Just point me to the FACTS. Thank YOU.
