At least as far back as March? I apologize for not being clear... I think that is Moderna, I was talking about Pfizer—and I should have specified Phase 3—sorry I did not specify...Phase 1 and 2 seem to be very small-sized trials, and according to someone I know who does Biostats on clinical trials, Phase 1 is healthy adults—not ill...no co-morbidities.

Not sure the Phase 1/2 trial size on Pfizer, but Phase 1 it was started April 29. #1c

And it seems they combined Phase 1 and 2.

NEW YORK & MAINZ, Germany—(BUSINESS WIRE)— Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) announced today that the first participants have been dosed in the U.S. in the Phase 1/2 clinical trial for the BNT162 vaccine program to prevent COVID-19. The trial is part of a global development program, and the dosing of the first cohort in Germany was completed last week. #1a

Jul 1, 2020 — ...from the ongoing Phase 1/2 clinical trial of four vaccine candidates will enable ... global Phase 2b/3 safety and efficacy study that may begin as early as ... Pfizer would work jointly to distribute the potential COVID-19 vaccine ...#1b

Phase 3 began last week July, first week August:

Pfizer and German biotech partner BioNTech have on the same day as rival Moderna kick-started a late-stage effort for their “best” attempt at an mRNA pandemic vaccine.

Moderna announced early Monday that, alongside a near half-billion extra in Biomedical Advanced Research and Development Authority dollars, it has started a boosted 30,000-patient phase 3 for its vaccine; not to be left out, Pfizer and BioNTech announced after-hours that they too were starting a late-stage attempt. #2

Thanks for the replies...I am trying to learn enough to have your level of trust to be an early market adaptor for experimental drug/new therapy...

At this point, I am still researching to find info to support my comfort zone...and I am taking the Zelenko protocol.
