I'd volunteer. I'm 41 and about to be up for my turn as an educator. I feel OK about the mitigations in my classroom and my overall level of risk, and a bit guilty about getting my dose earlier than most; a 50-50 chance of delaying my second dose doesn't appreciably make the risk picture worse.

If my second dose was delayed, odds are I'd end up with better long term immunity, too, even though my risk in the intermediate period would be higher.

No shit. That's why I said "enroll" -- this includes getting consent. I suspect finding 20k people to volunteer out of the ~10M dosed per week wouldn't be that hard.

The same kind of people who already enroll in any other kind of drug trial. "Who would volunteer for that study" doesn't make much sense of a question considering people are willing to do phase 0 studies of new drugs which are theoretically far more dangerous.

It could be beneficial for people that are further down the priority list and want to get vaccinated sooner. Especially since the people further down the list are less likely to die if they do get covid

I’d volunteer for a challenge trial, so obviously I’d volunteer for this.

Why not volunteer? One dose is apparently quite protective already. Most likely, there will be little difference which arm of the trial you end up on.

I would.
