The first 3 points seem pretty weak, but damn, it got suspicious from point 4 onwards.
Regarding point 1, yeah the Chinese stalled, but doctors in Wuhan were already texting each other about the weird infection, in November/December. I think it's possible a government lab took a sample of the virus and started to develop the vaccine even before an actual government acknowledgement, however irresponsible that is.
Point 2 feels like an accusation with no evidence, just based on prior behavior of someone in some other place, but also China.
Point 3 could just be coincidence.
Yeah but The Expertsâ„¢ would never lie to us about anything else.
