“For the first time in a long time, I feel very positive about this, because Donald Trump is not beholden to the pharmaceutical industry,” movement leader Andrew Wakefield told STAT in a phone interview.

“He didn’t rely upon [drug makers] to get him elected. And he’s a man who seems to speak his mind and act accordingly. So we shall see,” said Wakefield. A former doctor whose medical license was revoked, Wakefield launched the movement to question the safety of vaccines nearly two decades ago with a fraudulent study (which has since been retracted) suggesting that a widely administered vaccine against measles, mumps, and rubella can cause autism.

Wakefield and a small group of like-minded activists spent nearly an hour with Trump in the closing months of the presidential campaign. “I found him to be extremely interested, genuinely interested, and open-minded on this issue, so that was enormously refreshing,” Wakefield said.
