A vaccine scientist says being tag-teamed and dogpiled on by Elon Musk, Joe Rogan, and RFK Jr. all at once has been 'overwhelming'

The vaccine scientist Peter Hotez says it's been "overwhelming" getting tag-teamed on Twitter by some of the platform's most influential voices.

"You know, the attacks from the anti-vaccine lobby do come in waves. And this time, though, it's been one of the tougher ones. Because, as you pointed out, the physical stalking and the incessant threatening emails," Hotez told MSNBC's Mehdi Hasan on Sunday night.

"And the stuff online is just total whack-a-doodle. And let's face it, when you have RFK Jr. and Joe Rogan, and Elon Musk, all tag-teaming, those tres hombres at the same time," Hotez added. "That probably includes just about every follower on Twitter. So, it's pretty overwhelming."
