Robert F. Kennedy Jr. petitioned the F.D.A. to revoke authorization of the shots at a time when they were in high demand and considered life-saving.
Robert F. Kennedy Jr., President-elect Donald J. Trump’s choice to lead the nation’s health agencies, formally asked the Food and Drug Administration to revoke the authorization of all Covid vaccines during a deadly phase of the pandemic when thousands of Americans were still dying every week.
Mr. Kennedy filed a petition with the F.D.A. in May 2021 demanding that officials rescind authorization for the shots and refrain from approving any Covid vaccine in the future.
Just six months earlier, Mr. Trump had declared the Covid vaccines a miracle. At the time Mr. Kennedy filed the petition, half of American adults were receiving their shots. Schools were reopening and churches were filling.
Estimates had begun to show that the rapid rollout of Covid vaccines had already saved about 140,000 lives in the United States.
The petition was filed on behalf of the nonprofit that Mr. Kennedy founded and led, Children’s Health Defense. It claimed that the risks of the vaccines outweighed the benefits and that the vaccines weren’t necessary because good treatments were available, including ivermectin and hydroxychloroquine, which had already been deemed ineffective against the virus.
The petition received little notice when it was filed. Mr. Kennedy was then on the fringes of the public health establishment, and the agency denied it within months. Public health experts told about the filing said it was shocking.
