Trump says he received vaccine booster shot

Former President Donald Trump said he received a Covid-19 booster shot, revealing the news to former Fox News host Bill O’Reilly on Sunday during one of their “History Tour” live events.

O’Reilly also confirmed he received a booster shot, though neither said which one they received.

The crowd began to boo Trump after he said he had gotten his booster shot, though the former president discouraged the jeers.

When the New York Times' Maggie Haberman asked a Trump spokesperson why he changed his message on the vaccine and boosters, she received a handwritten note, signed “Donald.“ The first four words were underlined, according to the photo Haberman posted on Twitter.

"Must tell the truth — and very proud to have produced the 3 vaccines so quickly — million of lives saved worldwide — Best wishes Donald," the note said.

While there has been opposition to vaccinations among some conservatives — just 60 percent of Republicans are vaccinated, compared to 91 percent of Democrats, according to The New York Times — Trump has touted his administration’s role in developing the vaccine.

"I think this would have been the Spanish Flu of 1917 ... This was going to ravage the country, far beyond what it is right now. Take credit for it."

While Trump reiterated his opposition to vaccine mandates, he said to his supporters that when they doubt the vaccine's efficacy and safety, "you're playing right into their hands."

"What we've done is historic. Don't let them take it away," he said.

All Americans 16 and older are eligible to receive their booster shots, so long as they have received at least one dose of the Johnson & Johnson vaccine or two doses of either Moderna or Pfizer and are six months out from their last shot. The CDC recommends that all American adults 18 and older should receive a booster shot.

The Biden administration, as well as health agencies, have engaged in a massive booster push going into a second winter of Covid-19, saying they are crucial in offering sufficient protection against the Omicron variant of the coronavirus.
