It actually doesn't take long to have high confidence vaccines work. Roughly 30 days. Day 1- inject vaccine. Day 15 - infect virus. Day 30 - know it works.
Human challenge studies were a ethical no brainer.
Even other studies if we gradually increased the number of people allowed to take them would mitigate almost any real risk. So you let up to 1k people take it month 1, 10k month 2, 100k month 3, and so on. Basically no meaningful extra risk but faster results.
Vaccines have a very good safety record and efficacy record, this isn't like cancer which is much more speculative.
Banning vaccines is not the answer. Most US deaths were completely preventable.
I strongly agree with reducing red tape for biomedical testing, but this is a drastic oversimplification of the current scenario, and of vaccine efficacy.
