Pfizer did not do the studies. Pfizer is supposed to provide the answers to your questions. They did not. And they were not asked to.
Pfizer was allowed to skip dosage trials and travel trials.
But you already know that, don’t you.
From what my doctor told me, the third stage trials were done by Kaiser Permanente. I imagine other agencies also participated in the studies. Why would I care who did them? I have commented how the clinical trials were conducted in an earlier post. I am too lazy to pull that post out and bore you with the same information you can easily get. I remember that the dosage study was in the stage 1 clinical trials. I think they were continued in some of the later stages, but I am not sure or if they needed to. The dosage is being given at .3 milliliters.
We raced to create a vaccine without doing essential testing on a bio-weapon that mutates constantly. Then we advertised the sh_t out of it as if it were a used car that had to be sold for the end of the month quota. Then the powers that be lied their tails off constantly about what was in it, how effective it would be, why it might not work, and had little effect on the virus it was supposed to protect us from. What a deal!!
For me that's enough warning signs not to have any part of such a bio-weapon masquerading as a vaccine. And don't forget even big pharma knows not to call it a vaccine and to make sure they are bullet proof from lawsuits which they know are inevitable. Inevitable because they knew what they were doing all the time. They didn't care because it was mega-bucks.
Remember that old slogan:
FOLLOW THE MONEY!!
