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.

Kennedy has faced scrutiny from senators at his confirmation hearings over his plan to profit from vaccine lawsuits while serving as health secretary.

Kennedy has repeatedly questioned the efficacy and even safety of vaccines touted by most doctors as medical miracles responsible for saving tens of million lives globally.
