Dr. Anthony Fauci, the chief medical adviser to the president, clarified that the Biden administration's plan to administer 100 million vaccines during the president's first 100 days does not mean that 100 million people will be vaccinated against the coronavirus.

When President Biden announced his plan on Dec. 8, he said that his administration would get "at least 100 million COVID vaccine shots in the arms of people in the United States in the first 100 days" through a combination of increasing funding toward vaccination and expanding the priority vaccination groups to include people older than 65 years of age, essential workers, and those living in remote communities.
