Pardon me if I don't bother to read the propaganda.
The real-world purpose of gain-of-function research is the development of viral weapons. And EVERYONE - good guys and bad guys alike - can count on the Chinese to use those weapons when they kick off the really interesting part of WW3.
Some of the creatures in the swamp had a legitimate interest in the vaccines, simply because they're the only defense against such weapons. But don't expect all that to play out well when big pharma gets to play that game by their rules.
And keep this in mind: after the release of COVID-19 from the Wuhan lab, almost certainly from gross incompetence (which had been well documented before 2019), they continued their weapons development. Last year, they announced they had attained 100% mortality in humanized mice!
Those are the facts. People can deny reality, but doing so usually doesn't work out well in the long run.
