Going to a single dose would undermine the last remaining credibility of OpWarpSpeed. If you look at the published data it’s only 2 doses for both mRNA vaccines that provide reasonable virus neutralizing antibodies. And it’s only 2 doses that protect https://apple.news/AM61Z3Q8wTyuymHCy2BV9Jg
Asking the American
people to compromise their safety and protection because no one thought that we needed a health system to provide high throughput vaccinations is unacceptable. We have to stop being so mediocre, and do hard things. Under Trump we became a nation of wimps

We now need to implement a health system that can vaccinate 1.5 million Americans every day from now until the fall. We need leaders who welcome challenges and like to roll up sleeves. Not lazy feckless ones who are frightened by science textbooks
2 full doses. The problem is not vaccine production or at least not in a few weeks. The problem is no one bothered to do the calculations to know what it takes to vaccinate the American
people. So figure it out, open football stadiums, approve adeno vaccines, get ours into US

And stop with the mediocre half-baked post hoc analyses. If you are bored or feeling unstimulated, read a book, watch a movie, or learn to play chess
