The United States has administered a third dose of either Pfizer Inc or Moderna Inc’s COVID-19 vaccines to over 1 million people as of Wednesday morning, the U.S. Centers for Disease Control and Prevention said.
U.S. health regulators authorized a third shot on Aug. 13, for people with compromised immune systems who are likely to have weaker protection from the two-dose regimens.
The country has administered 371,280,129 doses and distributed 443,741,705 doses of the two-dose vaccines from Moderna and Pfizer/BioNTech, as well as Johnson & Johnson’s one-shot vaccine.
Those figures are up from the 370,212,027 vaccine doses the CDC said had gone into arms by Aug. 31 out of 441,332,155 doses delivered.
The agency said 205,527,578 people had received at least one dose while 174,600,017 people are fully vaccinated as of 6:00 a.m. ET on Wednesday.
