A total of 1,745,441 vaccine doses have been administered in long-term care facilities, the agency said.
The United States surpassed 24 million COVID-19 infections and 400,000 lives lost from the virus on Tuesday, according to a Reuters tally. The country has recorded more than 200,000 new cases and 3,220 deaths on average over the last seven days.
President-elect Joe Biden on Tuesday led a national memorial observance on the eve of his inauguration to honour those who died from COVID-19.
He has pledged to make coronavirus relief a top priority when he takes office on Wednesday.
Biden, eager to speed up COVID-19 vaccinations, has also promised 100 million doses injected during his first 100 days in office.
To achieve that goal he will push for the creation of new community vaccination centers in gyms, stadiums and schools, and will mobilise an additional 100,000 health care workers.
