Mark Tykocinski, a Yale trained molecular immunologist, became president of the university in 2022. Last week, a reporter from The Philadelphia Inquirer went through his personal Twitter account which had under 300 followers.

The Inquirer reported that Dr. Tykocinski had liked tweets from Berenson that criticized transgender surgeries for children and the efficacy of mRNA Covd vaccines.

“Two years after their introduction, the mRNAs Covid vaccines have proven to be what we all should have expected,” one tweet from Berenson argued. “Another in a long line of overhyped, rushed, profit-driven Big Pharma flops with weak long-term efficacy and a lousy side effect profile.”
