prematurely. here's what's at issue. there is some data for pfizer, the fda is looking at it. fda advisers are meeting on september 17th, so it's very possible that there could be a rollout of a pfizer booster on september 20th. but take a look at this chart. not every american has received pfizer. most americans who are vaccinated did get pfizer, 54% did, but still, 38% got moderna, and 8% got johnson & johnson. so the issue is what are we going to tell the people who got moderna and johnson & johnson? the other big issue here is that the messaging on this is really getting confusing, and the problem isn't the people who have already been vaccinated. the problem is the people who haven't been vaccinated. they don't trust the government, and when you hear this back and forth, they will say all the more reason not to even get one shot. and take a look at this number. more than a quarter of eligible americans have not gotten even one shot yet.
