US Health Secretary Robert F Kennedy Jr announced plans this week to cancel $500 million dollars of funding for mRNA vaccine development. The research was focusing on trying to counter viruses that cause diseases such as the flu and Covid-19.

Marnie Chesterton is joined by Professor Anne Willis, Director of the MRC Toxicology Unit at the University of Cambridge, to explore the claims made by The US Department of Health and Human Services that the technology “poses more risks than benefits”, and to look at the evidence behind the vaccines.

We also visit the most powerful computer the UK has ever seen at the University of Bristol, and explore how the Isambard-AI supercomputer is being used to carry out groundbreaking new research.

After last week’s call for our listeners to pay homage to the satirical songwriter and mathematician Tom Lehrer, who died at the age of 97, we hear a range of your brilliant musical tributes.

And Marnie is joined by journalist Caroline Steel to explore the week’s fascinating scientific discoveries.
