US President-elect Joe Biden was vaccinated against COVID-19 on Monday.
Biden previously said he would do it publicly to “build confidence in the scientific process.”
Several more prominent politicians received the vaccine last week, including Vice President Mike Pence, House Speaker Nancy Pelosi and Senate Majority Leader Mitch McConnell.
Distribution of the vaccine from Moderna also began on Monday, which was approved by the Food and Drug Administration on Friday.
Earlier this month, the first vaccine developed by Pfizer and BioNTech was registered in the United States.
First of all, medical workers and those who are in nursing homes are vaccinated.
The federal advisory board said Sunday that the next group should be people over 75, as well as those working in critical areas: firefighters, teachers and grocery workers.
The United States has seen a spike in the incidence over the past two months. Over the past week, the daily increase in infections has been more than 215,000 new cases.
According to Johns Hopkins University, the United States has the highest number of deaths from COVID-19 in the world, with the disease claiming more than 317,000 lives in the country.
