Over one million Pfizer/BioNTech vaccine doses have been administered in the United States, according to the US Centers for Disease Control and Prevention.
A Wednesday update to the CDC’s Covid Data Tracker said that nearly 9.5 million doses had been distributed and just over 1 million doses had been administered.
Doses distributed include both Pfizer/BioNTech and Moderna Covid-19 vaccines. Doses administered include only Pfizer vaccines. Administration of Moderna vaccinations just began on Monday.
The CDC notes there is a lag in data as it is reported to the agency; health care providers report doses to states, territories and public health agencies up to 72 hours after administration.
