One in four adults in the United States have now received their first shot of the coronavirus vaccine, a White House official said Wednesday.

Andy Slavitt, the senior adviser to President Biden’s coronavirus response team, announced the vaccination update in a post on Twitter.

More than 95.7 million COVID-19 doses have been administered in the country since inoculation efforts began in mid-December, according to the latest data from the federal Centers for Disease Control and Prevention.

Over 62.4 million people or 18.8 percent of the population have gotten at least one vaccine shot, while 32.9 million people or 9.9 percent of the population have been fully vaccinated, according to the CDC data.

There are currently three COVID-19 vaccines available in the US – a two-dose shot made by Pfizer, another two-dose shot by Moderna and the newly approved single-dose jab by Johnson & Johnson.
