I have no idea what's "going on in China", and neither do you. First of all, you'd have to believe their ridiculous claims that covid cases were at near zero in China while the rest of the world went through a pandemic. 

I do know that Joe Biden and his army of ankle biters repeatedly promised that the MRNA vaccines were going to stop transmission, which they didn't. 

And if the lockdowns had stopped transmission, we wouldn't be talking about vaccines in the first place.

Bringing up China in anything COVID related, especially as a good example, is pretty stupid. They don't have half a handle on things over there. 


That said, a lockdown, aka a quarantine does stop transmission. A virus can't travel very far but itself, it needs the host to be in close proximity to other people in order to infect them. The problem with lockdowns as they were in the west was that they were designed by politicians, and employed multiple loopholes and other failings to get them enacted.
