Those figures are up from the 391,152,574 vaccine doses the CDC said had gone into arms by Tuesday out of 472,646,105 doses delivered.
The agency said 214,043,376 people had received at least one dose while 185,537,265 people are fully vaccinated as of 6:00 a.m. ET on Wednesday.
The CDC tally includes two-dose vaccines from Moderna and Pfizer/BioNTech , as well as Johnson & Johnson’s one-shot vaccine.
About 3.68 million people received an additional dose of either Pfizer or Moderna’s vaccine since Aug. 13, when the U.S. authorized a third dose of the vaccines for people with compromised immune systems who are likely to have weaker protection from the two-dose regimens.
