Why is no one talking about the fact that the entire study that gave the "fda approval" only looked used participants that were 1) symptomatic, and 2) did not have prior infection.

The study only looked at Vaccine Efficacy as compared to symptomatic participants and without prior infection / antibodies. There are tons of cases of covid that are not symptomatic, so only comparing vaccine side effects to the cases that are symptomatic is going to skew the results and data. Symptomatic cases are naturally the more severe cases. And also only looking at VE in participants without prior infection skews the results and isn't representative of the real world. Since they only looked at people without antibodies/prior infection, the vaccine should at a minimum, only be authorized for those without prior infection!

From the study itself: "A primary objective was to evaluate the efficacy of BNT162b2 to prevent laboratory-confirmed symptomatic COVID-19 occurring ≥7 days after Dose 2 in participants without serological or virological evidence of past SARS-CoV-2 infection before and during the vaccination regimen."
