The problem is records on 1st, 2nd and 3rd doses may not be correctly linked, especially if you get them at different facilities. So CDC may overestimate the % who has gotten at least one dose, because some people are counted twice. But, they may underestimate % fully vaccinated. — PolitiTweet.org

@NateSilver538 Why don't we just know how many took the vaccine? Isn't this stuff being recorded??
