More adding support for delayed 2nd dose strategy. @mtosterholm + @mlipsitch are supportive. Early calls to consider this (notably op-ed by @michaelmina_lab + @zeynep in mid-Dec) were too quickly dismissed by some, IMO.
It's a race against new variants.https://www.cidrap.umn.edu/news-perspective/2021/02/experts-tout-delaying-2nd-covid-vaccine-dose-us-deaths-mount …

Insisting that the only scientific way was whatever the initial trial happened to be—which isn't a practice set in stone, is modified routinely for other vaccines, and given the emergency we face, def something to discuss—kind of became an own-goal, I think. So now it's harder. +

Meanwhile, both WHO and CDC have said six weeks is okay but we can't even do that, partly because of that unnecessarily rigid messaging. We could have had better data, we don't. UK could have had a more targeted approach, they don't.

know that you and Michael wanted data. And we should’ve collected in HCW like myself. We had an opportunity and we squandered it with a largely disjointed initial rollout. We could have had this question answered. I’m with you on that.Thanks. Twitter will use this to make your timeline better. UndoUndo

So if we are to change course & allow some delay (which admittedly I have resisted in the past but am open to changing my mind), I’m just arguing for a fully transparent & open messaging campaign about it—globally.

Yeah, and agree, it is harder now. Part of wanting data, urgently, was that it wasn't hard to see this was going to come up, and if we act late, we always get into these tough situations where we pivot out of necessity, but lose trust.
