Perhaps a second source? Taiwan commenting on the wrongdoings of China seems a little...problematic

The article discusses a 2014 U.S. ban on virus gain-of-function experiments. Looking it up, I found this 2015 Nature article which also mentions the ban.

Here's a link to the 2017 Wuhan labs research paper that was quoted: "we constructed a group of infectious bacterial artificial chromosome (BAC) clones with the backbone of WIV1 and variants of S genes from 8 different bat SARSr-CoVs" https://journals.plos.org/plospathogens/article?id=10.1371/j...

Right on, it should be a major red flag: the fact that a virus with high human tropism was brought to the world's attention in a city that's home to only one of two BSL4 labs in the world and that the lab studies bat coronaviruses in context of human infection.

There was a case in Italy in Milan in November 2019, as we get to know today. Can we stop speculating?

Can we stop being blind to possibilities? Unless you can prove that it originated in Italy you ought to stop silencing other views that make you uncomfortable.

So they specifically tried and succeeded to turn multiple virus' that didn't effect humans into ones that did? What is the purpose of doing that to begin with?

The usual purpose of these studies is to anticipate wild strains doing the same thing, to get ahead of pandemics, and develop vaccines before it spreads.

Unfortunately it's a waste if you: Don't heed the research anticipating wild spread or publish results, don't develop a vaccine, and/or accidentally release your enhanced virus before a wild strain pops up.

Has any virus actually been headed off with a vaccine already having been created in anticipation of the virus coming into existence eventually? That's really interesting

Edit: and how useful would it be if it was? I was under the impression that covid vaccines were made extremely quickly and that it was regulatory issues that held it until now
