Joe Rogan and Elon Musk's Twitter feud sparks harassment of vaccine scientist.

Vaccine scientist Peter Hotez was accosted outside his home by anti-vaxxers after a Twitter exchange with podcaster Joe Rogan, who challenged him to debate Robert F. Kennedy Jr. Hotez has frequently debunked Covid-19 vaccine misinformation on his social media accounts during the pandemic. The confrontation came after Hotez tweeted in support of a Vice article that criticized Spotify’s handling of vaccine misinformation on Rogan’s show. Last year, artists such as Neil Young and Joni Mitchell asked the streaming music company to pull their music from the platform after Rogan’s frequent false and inaccurate claims about Covid-19 and vaccines on the “Joe Rogan Experience.”
