i believe the chinese have done this on purpose as a safety precaution for their people
they want a higher level of immunity but something that doesn’t have nearly the risk to generate cytokine storm issues in their people
An unasked question.
Do you want to have your genetic make-up permanently altered to fight off a virus that won’t be around two years from now?
What would be the point of your immune system making antibodies for a virus that has long sense mutated to a different form?
I believe the Chinese wanted fast cash pure and simple, and like the contaminated masks and PPE and test kits they sent out, didn’t give a hot potato about the rest of the world, counting on world dominance and ‘trade agreements’ to muzzle any criticism after the fact, smaller complainers swatted away. It’s been their modi operandus for 30 years. They didn’t count on the UK and US producing multiple vaccines in 9 months.
