This guy's part of a tight nit community of trusted Vaccine safety advocates, and he has a Phd. Very honest assessment of scenarios, with science and rational, including even if FF, Bio-warfare, Lab accident, or vaccine experiment on a mass scale gone amuck.
Basically, it may be that a bad vax experiment (they've failed trying on animals) makes people much more affected by ANY Corona Virus the next time around. Since it would be a live virus vaccine, it would shed. So you'd have people who got the vaccine getting infected and others getting infected. All would get over it at a reasonable rate, but those that got the vaccine would go on to die at a much higher rate (2nd infection) while the ones that caught it from them would not be so unlucky. He says if he's right, then you should see MUCH better outcomes for anyone elsewhere in the world who become infected. (much lower death rates).
