Injecting people with the vax, and then injecting them with Coronavirus will determine if a vaccine works - and is safe. As it stands some of the vaccines may already work, and be safe.
However, there is faffing around with long drawn out human testing trials.
Currently, people get the vaccine, then over the next 12 months if no one gets Corona - it must work.
That takes ages... Even at the advanced current stages.
I am in favour of challenge tests to speed up the availability of the vaccine in a few scenarios:
- Prisoners with life sentences like murderers - can be pardoned and paid 10 million. . They have to volunteer willingly of course.
- Young people between 18-28 have a 1/30.000 chance of dying. Again they get paid 10 million each if they want to partake in challenge tests.
- Anti-vaxxers. We just randomly round them up and make them the guinea pigs.
