Just to set the record for at least the Moderna Study:
Trials (Phase 1) started April 2020. This was "safety testing", under 100 people.
Phase 2 was testing (May 2020?) to get the dosage correct, under 1000 people.
I was in Phase 3, expanded testing. For Moderna, this was 30,000 people. It started in July 2020. One third were control group, and I was in the control group. I received the vaccine (first dose) Jan 25th, 2021.
So there is data going back 1 year for about 100 people each in the Moderna and Pfizer studies. And 1000 people for 11 months. And 20,000 people, there is data for an average of about 7 months (Late July to late October).
