How Kennedy Has Worked Abroad to Weaken Global Public Health Policy

Robert F. Kennedy Jr., who is in line to lead the Department of Health and Human Services in the next Trump administration, is well-known for promoting conspiracy theories and vaccine skepticism in the United States.

But Mr. Kennedy, an environmental lawyer, has also spent years working abroad to undermine policies that have been pillars of global health policy for a half-century, records show.

He has done this by lending his celebrity, and the name of his nonprofit group, Children’s Health Defense, to a network of overseas chapters that sow distrust in vaccine safety and spread misinformation far and wide.

He, his organizations and their officials have interfered with vaccination efforts, undermined sex education campaigns meant to stem the spread of AIDS in Africa, and railed against global organizations like the World Health Organization that are in charge of health initiatives.

Along the way, Mr. Kennedy has partnered with, financed or promoted fringe figures — people who claim that 5G cellphone towers cause cancer, that homosexuality and contraceptive education are part of a global conspiracy to reduce African fertility and that the World Health Organization is trying to steal countries’ sovereignty.
