Robert F. Kennedy Jr.a prominent anti-vaccine activist, was tapped by the president-elect Donald Trump to lead the Department of Health and Human Services, the main health agency of the United States.

In a social media post, Kennedy pledged to work to end chronic disease, clean up corruption and give Americans the data they need to make informed decisions, vowing to Trump that will work for “Make America Healthy Again.”

Kennedy ran for president in this year’s election as an independent before dropping out in August and supporting Trump in exchange for a role in the Republican administration.

The following are some of the main policy positions RFK Jr. has taken in recent months in editorials, tweets and interviews, according to Reuters.

Vaccines

Kennedy criticized vaccines, including manufacturing false medical claims that vaccines are linked to autism. He opposed state and federal restrictions on COVID-19. However, he rejects the idea that it is “anti-vaccine“and told Reuters that every American who wants a vaccine for themselves or their children will have access to it.

Processed foods

Kennedy calls for a ban on hundreds of food additives and chemicals such as food coloring. He called for removing ultra-processed foods from school lunches as part of a goal to reduce the incidence of diet-related chronic diseases.

Nutrition guide

He said the Food and Drug Administration’s nutrition department, which handles nutrition labels on foods, “has got to go. They are not doing their job. It does not protect our children”.

Medications for weight loss

Kennedy criticized popular drug Novo Nordisk NOVOb.CO Ozempic, which is often prescribed for weight loss, saying it focuses on the symptoms of the obesity crisis rather than repairing the food system and that the drugs “cheer up the wallets” of pharmaceutical executives.

Drug research

Kennedy said half of the research budgets at the National Institutes of Health should be directed toward preventive, alternative, and holistic approaches to health. He also said he wants to lay off 600 employees at the NIH.

Raw milk

Kennedy wants to end the FDA’s “war on public health,” including what he called “aggressive suppression” of psychedelics, peptides, stem cells, raw milk and more.

He advocated holistic health practices such as drink raw milka practice that has been associated with disease outbreaks.

fluorine

He asked fluoride removal from public water.

The day after Trump’s victory, Kennedy MSNBC said in an interview that “fluoride will disappear”. He also repeated the false claim that fluoride is “lowering our children’s IQ.”

Medical schools

He said nutrition courses should be required at federally funded medical schools.

Farms

He called for a review of standards on pesticides and other chemicals, as well as reform of crop subsidies.

The Department of Health and Human Services oversees drug regulation, public health agencies, including the Centers for Disease Control and Prevention, and health insurance for more than 140 million people, including the poor, those age 65 and older, and people with disabilities through Medicare and Medicaid.

HHS had a budget of $3.09 trillion for fiscal year 2024, representing 22.8% of the US federal budget.
