Okay, I'll cut to the chase: The best piece of evidence you seem to have is that Zhou Yusen filed a patent for a COVID-19 vaccine in Feburary 2020. First off, I could only find evidence of this on already shaky fake-news websites (yeah, I actually had looked into this before I wrote the article, the reason I didn't mention it was because it wasn't worth mentioning) but I'll give you the benefit of the doubt. First off, by that point point COVID-19 had already been in China for roughly three months, so it's likely even if it didn't start in a lab they would have already began to study it. Second off, to put it simply, that's not how patents work.

For that matter, what am I supposed to take from this information? Was China patening a COVID-19 vaccine specifically to stop the US from creating one--because, if so, they did a rather bad job, For that matter, if China had a COVID-19 vaccine, why would they not send it to other nations--most notibably the African and Asian countries they're looking to increase their power over? Basically, until you can show me evidence Yusen had the formula for a working vaccine in Feburary 2020, I don't care what was filed.

I'll end by pointing out "the most obvious supposition that the virus in that town came from the virus factory in that town," also has a small issue with it. The fact is, Wuhan, China is larger than the state of Deleware. The first outbreaks of COVID-19 in Wuhan occurred roughly seventeen miles away from the lab that everyone keeps talking about. To put it simply, this claim still has no evidence to back it up and your pleas for "research" only showed me that you had failed to do any yourself.
