Former President Donald J. Trump recommended in a nationally televised interview on Tuesday evening that Americans who are reluctant to be vaccinated against the coronavirus should go ahead with inoculations.
Mr. Trump and his wife, Melania, were vaccinated in January. And vaccine proponents have called on him to speak out in favor of the shots to his supporters — many of whom remain reluctant, polls show.
Speaking to Maria Bartiromo on “Fox News Primetime,” Mr. Trump said, “I would recommend it, and I would recommend it to a lot of people that don’t want to get it — and a lot of those people voted for me frankly.”
He added: “It is a safe vaccine, and it is something that works.”
While there are degrees of opposition to coronavirus vaccination among a number of groups, polling suggests that the opinions break substantially along partisan lines.
A third of Republicans said in a CBS News poll that they would not be vaccinated — compared with 10 percent of Democrats — and another 20 percent of Republicans said they were unsure. Other polls have found similar trends.
Mr. Trump encouraged attendees at the Conservative Political Action Conference in Orlando, Fla., late last month to get vaccinated.
Still, Mr. Trump — whose tenure during the pandemic was often marked by railing against recommendations from medical experts — said on Tuesday that “we have our freedoms and we have to live by that, and I agree with that also.”
With President Biden’s administration readying television and internet advertising and other efforts to promote vaccination, the challenge for the White House is complicated by perceptions of Mr. Trump’s stance on the vaccine.
Asked about the issue on Monday at the White House, Mr. Biden said Mr. Trump’s help promoting vaccination was less important than getting trusted community figures on board.
“I discussed it with my team, and they say the thing that has more impact than anything Trump would say to the MAGA folks is what the local doctor, what the local preachers, what the local people in the community say,” Mr. Biden said, referring to Mr. Trump’s supporters and campaign slogan “Make America Great Again.”
