Nearly 34 million doses of Covid-19 vaccine have been administered in the United States, according to data published Wednesday by the US Centers for Disease Control and Prevention.
The CDC reported that 33,878,254 total doses have been administered – about 61% of the 55,943,800 doses distributed. That’s about 1.1 million more administered doses reported since yesterday.
The pace of vaccinations has steadily risen over time.
On Dec. 30, the seven-day average was about 255,000 shots per day.
That number jumped to 359,000 on Jan. 6; 710,000 on Jan. 13; 892,000 on Jan. 20; 1.16 million on Jan. 27; and now 1.32 million on Feb. 3.
At the current rate, every adult in the US could be fully vaccinated in about a year.
Assuming 75% of US adults must be fully vaccinated to achieve herd immunity, the US could reach this threshold around Halloween.
Just over 8% of the US population – more than 27 million people – have now received at least one dose of the vaccine, and about 6.4 million people have been fully vaccinated, CDC data shows.
Note on the data: States have 72 hours to report vaccine data, so data published by the CDC may be delayed – and may not necessarily mean all doses were given on the day reported.
