In February of this year, Robert F. Kennedy, Jr. sent a letter to the Chairman and other members of the CDC’s Advisory Committee on Immunization Practices (ACIP) on behalf of Children’s Health Defense. Aware that ACIP was planning to consider recommending Merck’s human papillomavirus (HPV) vaccine—Gardasil 9—for all women and men 27 to 45 years old, Kennedy informed the committee that Children’s Health Defense would consider such a recommendation “reckless” based on the safety information available.
