According to data released Wednesday by the U.S. Centers for Disease Control and Prevention, nearly 34 million doses of Covid-19 vaccine have been administered in the United States.
The CDC reported that 33,878,254 total doses were administered, approximately 61% of the 55,943,800 doses distributed. They are approximately 1.1 million most reported administered doses since yesterday.
The pace of vaccinations has steadily increased over time.
As of December 30, the seven-day average was about 255,000 shots a day.
That figure jumped to 359,000 on Jan. 6; 710,000 on January 13; 892,000 on January 20; 1.16 million on Jan. 27; and now 1.32 million on February 3rd.
At the current rate, all adults in the United States could be fully vaccinated in about a year.
Assuming that 75% of American adults must be fully vaccinated to achieve herd immunity, the U.S. could reach that threshold around Halloween.
Just over 8% of the U.S. population (more than 27 million people) have now received at least one dose of vaccine and approximately 6.4 million people have been completely vaccinated, according to CDC data.
Note on the data: States have 72 hours to report vaccine data, so data released by the CDC may be delayed, and does not necessarily mean that all doses were given on the reported day.
