I Was Wrong: We Can’t Skip Phase 3 Vaccine Trials

I Was Wrong: We Can’t Skip Phase 3 Vaccine Trials

Warp speed is fast enough

Yesterday, amid a Twitter tempest, we asked readers whether society should wait on the results of large clinical trials before distributing Covid-19 vaccines. The answer, for the majority, was yes, please.

About 61% of respondents said Phase 3 data are key to understanding whether a vaccine actually works, and any widespread use should come only after studies are complete. The remaining 39% embraced thinking outside the box in light of Covid-19’s disastrous effects on health and society.

This may seem fairly obvious — clinical trials determine whether medicines work — but there are some prominent proponents of cutting corners when it comes to Covid-19 vaccines. Among them was Stephen Salzberg, a professor of biomedical engineering at Johns Hopkins whose editorial urging immediate vaccination blew up on Twitter over the weekend, finding at least some defenders and many more critics. It’s worth noting that Salzberg’s follow-up piece is titled “I Was Wrong: We Can’t Skip Phase 3 Vaccine Trials.”
