So, basically more conspiracy theories.
First of all, it is well known that China has a bioweapons program. Almost all developed, militarily powerful countries do. We have one too.
Second, the guy interviewed is a FORMER intelligence analyst. Former. As in, he has no idea what's happening now, because the people who CURRENTLY hold clearances to know that type of information are not allowed to share it with anyone who also doesn't have the proper clearance. His information is as outdated as the last year he had access to intelligence.
Is it possible this is a lab developed virus that escaped somehow? Sure. Is it likely that China would purposely release it on it's own people? No. Is it likely that it's all being done to "sell more vaccines." Absolutely not.
However, it is in no way suspicious that China may be developing propaganda to blame the US in some way for this. That's par for the course for them.
The current best guess is that the virus originated in snakes sold at a Wet Market in Wuhan. Wet markets are a crazy thing, and really should not exist at all. They are unsanitary, filthy, and the root of much illness.
