Vaccines could have been delivered earlier with human challenge trials. Moderna was slowed by a month due to FDA demand for more Diversity in its clinical trial. It turned out its vaccine works fine on all races. Pfizer likely delayed announcing by a week to not help Trump.https://twitter.com/NateSilver538/status/1373400414108942337 …

Replying to @Steve_Sailer
The fact that they're *still* not doing human challenge trials and instead saying things like "we don't know if the vaccine is helpful at preventing the spread" is madness. There have been millions of people vaccinated. JUST DO A CHALLENGE TRIAL.

I don't know about "smart" but they're certainly unwavering. "No challenge trials, no matter what - only bureaucracy"
