Kennedy Jr. is revising his ethics agreement to divest his interest in litigation against an HPV vaccine maker and directing the stake to his adult son, The New York Times reported Friday, citing a written response to questions from senators who are weighing his confirmation as Health and Human Services secretary.

Robert F. Kennedy Jr. spent two days this week insisting to senators that he’s not anti-vaccine. He said that he instead supports vaccinations and will follow the science in overseeing the $1.7 trillion Department of Health and Human Services, which, among other duties, oversees vaccine research, approval and recommendations.
