“Researchers noted that they could not separate out the effects of vaccination from infection.”
Then they are either idiots or they’re lying. Of course they can separate them
Their orders were to not separate then they’ll need to be able to pretend the effects from the vaccine are no different from not having received the vaccine. Which is likely a lie.
If it were not, they would do a study on people who had no vaccine but got Covid.
It would be easy to do
Sorry double post
