Biden receives 2nd COVID-19 booster

President Biden received his second COVID-19 booster dose at the White House on Wednesday, a day after the Food and Drug Administration authorized a fourth dose, or second booster shot, of the Pfizer and Moderna vaccines for adults age 50 and older and immunocompromised groups.

As had been the case with his previous doses, Biden, 79, received the shot on camera, part of the administration’s effort to promote vaccinations.

He declined to answer shouted questions from reporters about Russian President Vladimir Putin's monthlong war in Ukraine.

“I'm feeling great,” Biden said as he received a booster for the Pfizer vaccine. "It didn't hurt a bit."

Biden also announced the launch of a new website, COVID.gov, that the administration is calling a "one-stop shop" for information on coronavirus tests, vaccines and treatments.

The president received his first Pfizer booster shot in September. He received his first two doses of the vaccine shortly before his inauguration in January 2021.

According to the Centers for Disease Control and Prevention, more than 65% of the U.S. population is considered fully vaccinated — people who have received at least two doses of the Pfizer or Moderna coronavirus vaccines or the one-dose Johnson & Johnson shot.

But just 45% of Americans have received a booster dose, according to CDC data.

According to Johns Hopkins University, there have been more than 80 million confirmed coronavirus cases in the U.S. since the beginning of the pandemic — far more than in any other country in the world. More than 978,000 Americans have died as a result of complications from COVID-19.
