Not a single one of those health authorities allowed vaccine challenge trials. That tells you how much they care about saving lives versus how much they care about not getting blamed for any deaths.
- yellow_postit 6y agoIt does appear that challenge trials are starting, a search easily turned up this UK one: https://ukcovidchallenge.com/covid-19-volunteer-trials/ https://ukcovidchallenge.com/covid-19-volunteer-trials/ The main benefit of challenge trials is to speed up development as I understand it not to broaden risk estimates.

We could have shipped vaccines 3 months sooner and saved hundreds of thousands of lives. Unfortunately, no health authority was willing to risk blame for any disabilities or deaths stemming from deliberately exposing consenting people to covid. So we had to use much larger sample sizes and wait longer to know which vaccine candidates were effective.
