Spotify is refusing to comment on remarks from its most popular podcast host Joe Rogan casting doubt on the need for some people to get the coronavirus vaccine.

Spotify CEO Daniel Ek declined to answer a question Wednesday about Rogan’s recent suggestion that healthy young people should not get the vaccine.

“I don’t have any specific comments on that,” Ek told Bloomberg in an interview. “What I will say is we have 8 million creators, and hundreds of millions of pieces of content. We have a content policy and we do remove pieces that violate it.”

Later, during Spotify’s regular earning call, the company singled out Rogan’s contribution to their podcast user growth in the first quarter.

“December had a very strong month, particularly with Joe Rogan going exclusive,” chief financial officer Paul Vogel said Wednesday.
