Robert F. Kennedy Jr., who's nominated to become the next health secretary, asked the federal government to revoke its authorization of all COVID-19 vaccines in May 2021, just as vaccinated Americans began returning to a sense of normalcy after pandemic lockdowns.

... John Moore, a professor of immunology at Weill Cornell Medical College, called Mr. Kennedy’s request to the F.D.A. “an appalling error of judgment.” Gregg Gonsalves, an epidemiologist at the Yale School of Public Health, likened having Mr. Kennedy lead the federal health agencies to “putting a flat earther in charge of NASA.”
