Podcaster Joe Rogan sought to clarify his stance on Covid-19 vaccines after suggesting young, healthy people didn’t need them.

The comments on his popular podcast Thursday came a day after Dr. Anthony Fauci, White House chief medical advisor, called Mr. Rogan’s advice incorrect and said unvaccinated people “are propagating the outbreak” as they can infect others who may be at severe risk of illness from the virus.

On his Thursday show, Mr. Rogan, 53 years old, said the argument that young, healthy people should think about others who are at risk “makes sense.” He also said he had been going to get the Johnson & Johnson vaccine, but that scheduling didn’t work out before administration of the vaccine was temporarily halted.

When his guest, stand-up comedian and actor Andrew Santino, called himself a sheep for getting the vaccine, Mr. Rogan said, “it’s not being a sheep, there’s some legitimate science behind this.”

“I’m not an anti-vax person,” he said. “In fact I said I believe they’re safe, and I encourage many people to take them.”
