Harvard epidemiologist locked out from Twitter account after criticizing masks

Martin Kulldorff claimed high-risk individuals were ‘naively fooled’ into thinking masks work.

A high-profile Harvard epidemiologist this week was locked out of his Twitter account after publicly challenging the mainstream pandemic orthodoxy on face masks.

Martin Kulldorff, a professor of medicine at Harvard Medical School and a biostatician and epidemiologist, on Friday wrote that “some older high-risk people” had been “naively fooled to think that masks would protect them,” leading some of them to “not socially distance properly” and consequently die from COVID-19.

“Tragic,” he wrote further. “Public health officials/scientists must always be honest with the public.”

Kulldorff was subsequently locked out of his account. Pictures circulated on Twitter of an apparent message from the company informing him the tweet had “violat[ed] the policy on spreading misleading and potentially harmful information related to COVID-19.”

Kulldorff confirmed the lockout to Just the News on Saturday.

"My Twitter account was locked because of a tweet about masks that I posted yesterday morning," he said.
