Very important distinction: giving flexibility for states to delay 2nd dose a few weeks (while production ramps is) is NOT about denying a 2nd dose. It’s about acknowledging the benefit NOW of ⬆️ the number of people who can get 92% protection vs giving some 94% protection. 👇🏽 
This is not about 1 dose vs 2 (at least from my POV). I still feel the 2nd dose is important for variants, and likely for durability of protection. But in the real world (ie NOW) the way we best stop spread and variants is to give more people some (92%) protection.
With us approaching 20% vax rates in some places/ groups, here’s a real world possibility:
A) 10 strangers in a room, 2 fully vaxed (94% protection)
B) 10 strangers in a room, 4 with 1 vax dose (92% protection).
Which room do you feel has greater risk of spread right now?🤔

Science /projections are often done in a lab or based on best case/ condition scenario (eg a world of unlimited vaccines) - but the challenge is real world application. In the real world we are racing against the virus, and giving flexibility to delay 2nd dose could help us win.
