That's single dose, so you gotta double it. And account for like 40% of the country that are not sure if the pandemic is real and/or if the vaccine is designed to have Bill Gates track them. And the fact that kids can't get it yet (and who knows when we will know), which would severely slow things down.

Right now we are production-constrained, and somewhat distribution constrained since every state is handling it differently. But soon enough we will be constrained by people's unwillingness to get vaccinated, and then things will get really fucking annoying.
