The Global Story: Will the new cancer vaccine survive RFK Jr’s America?

A new personalised vaccine given in combination with a drug has stopped skin cancer returning in patients during a trial, representing a potentially watershed moment in cancer treatment. Scientists used mRNA technology, which was used for some Covid-19 vaccines.

But that technology - and vaccines more generally - have become increasingly controversial in the United States since the Covid-19 pandemic. The Health Secretary Robert F Kennedy Jr, is a vaccine sceptic. In August 2025 cancelled $500m (£376m) in funding for mRNA vaccine research. The move impacted 22 projects being led by major pharmaceutical companies, including Pfizer and Moderna, for vaccines against bird flu and other viruses, according to Kennedy’s department.

We speak to Tom Whipple, host of the BBC’s Inside Science programme, about the science of this new vaccine. And we ask how funding cuts for vaccine research could impact health outcomes not just for Americans, but for the world.
