Should we delay 2nd Covid shots to get more people a 1st shot? @Bob_Wachter: Yes. If "after one dose you can get people 80% protected...it's not even very much of a close call." @angie_rasmussen: Maybe not. "My concern really is that by delaying...that 80% protection may wane."

Kudos to @MehdiRHasan for having 2 doctors participate in this discussion rather than 2 pundits.

The key is the next step in the argument. Sensible science suggests that the risk of efficacy waning significantly below the 80% is pretty low.

I believe this was tried in the UK and didn't work.

Supply isn’t are problem... people willing or able to get the vaccine seems to be our problem now.

Given that it takes around 2 weeks to build in protection after a first dose, in a high covid environment where you are attempting to outflank the virus it would seem pragmatic.

Why is this still a debate? Pfizer, Moderna and the CDC have said that the vaccines are most effective if given 3 and 4 weeks apart. So, how about we just listen and do it?!

This is a good example of 2 smart, knowledgeable people disagreeing over a complex policy issue in a dynamically changing information environment. This is hard problem. Those happen, but I'm sure glad to see 2 experts arguing rather than typical talking heads.

The US missed it’s chance to do the right thing. In places like Chicago, demand far outstrips the ability to vaccinate, and we could’ve vaccinated twice as many by now if we’d done one dose and postponed second doses to June.
