Robert F Kennedy Jr, US Secretary of Health and Human Services
Born into arguably the most prominent US Democrat family, RFK Jr was appointed into his current office by the Republican Donald Trump, following the Presidential election in 2024. RFK Jr had been an independent Presidential candidate, but dropped out and endorsed Trump. During that time, Trump recognised a fellow vaccine sceptic and that might be one of the reasons for his appointment.
RFK Jr is an environmental lawyer by training, and has had a chequered lifestyle, well documented by Wikipedia. He has been very active in his current post, taking some actions which confirm his vaccine hesitancy (which goes back to 2001) and which worry me.
Here are some examples raising concerns
- Sacking of 8 members and appointment of prominent vaccine sceptics to the important decision making committee (the vaccine advisory committee of the US Centers for Disease Control and Prevention) 1
- Response to measles outbreak in Texas in 2025, where initial reluctance to promote MMR vaccine (RFK Jr initially suggested Vitamin A) changed on the ground after 5 deaths to support MMR, a partial U turn2
- Initial concerns from the President and RFK Jr regarding a possible link from use of paracetamol in pregnancy to autism and ADHD3.4, subsequently debunked5
- Cuts of $500m in the budget to support mRNA vaccine research (mainly for Covid and Flu vaccines)6, affecting at least 19 projects
- Plans to block publication of scientific research in reputable journals like the Lancet and the NEJM7
- Reducing the number of routine vaccinations in the US from 11 to 7 jabs8, including routine covid vaccination
Conclusions
Mr Kennedy has been an entrenched opponent of vaccination for many years. His experience in environmental law, for example when he was successful lawyer in the case against Dupont who were polluting West Virginia from a zinc plant, may well have led to excessive distrust of large pharmaceutical companies.
Vaccine policies from the US will have a big impact on other countries9 – “they are global standard bearers for public health policy” 10.
In the longer term, cuts in research funding will affect the US, and have worldwide consequences.
