FDA Commissioner Marty McCary says the agency will require much stricter evidence that vaccines are safe and effective.

McCary says the new approach was prompted by evidence that the deaths of at least 10 children were caused by the COVID vaccines.

McCary's top deputy, Vinay Prasad, made that claim in an email distributed Friday.

NPR obtained the email after it was reported by other news organizations.

Independent public health experts, however, questioned the claim that the COVID vaccines caused these deaths, citing the administration's pattern of making unsupported and misleading claims.
