Revisionism in action?
It was all discussed here

The latest theory on how Covid escaped the lab (possibly, not proven) was from US gain of function research being moved to Wuhan to avoid US regulations.
There were congressional hearings about this.
Masks, social distancing, lockdowns were all proven to slow down the spread, the evidence is in that thread. Many studies were done comparing the spread of the virus in different countries, correlations made with different measures, different living situations, different demographics, different population density. And all the opposites (ignoring lockdowns, social distancing, etc) have shown to increase the spread of the virus.
(It's not so much standing apart that stops you from getting it, it's having less people together, discouraging people from getting together, either by making masks mandatory, limiting occupancy, better ventilation, that slowed down the spread)
Never did anyone claim that one measure (like masks or vaccines) would make you immune to catching covid. The point of the vaccines was to give people a head start on beating the virus. It doesn't make you immune, it gives your immune system a heads-up of the virus so it can counter the virus faster. Just like the flu shot doesn't prevent catching the flu, it helps you deal with the flu. (and survive the flu for older people)
The vaccines saved many lives. See New Zealand which kept the virus at bay the longest with strict measures, then lifted restrictions after vaccinations and still has the lowest death toll from Covid over all.
Ofcourse there were many shady things going on with the vaccines, like the latest post in that thread.
Interesting that it's all coming up again with Trump returning... Disinformation wars starting all over.
