Rather, it was a meta-analysis (not firsthand work) performed in China. I'm not even sure you read that article at all (otherwise you would have noticed the correction), although I'm now 100% sure that you have no biomedical background whatsoever, even at a college undergraduate level.
You probably didn't even read that antivaxxer's blog either, or you would have noticed that he was accusing China of engineering the coronavirus!
Any why did you repost some random blogger on Baidu who could have easily just made everything up? Blindly repeating groundless conspiracy rubbish is exactly the opposite what anyone should be doing. I expected that you would be the last person to get caught up in the hysteria, but I guess I was wrong.
