What is RFK doing to vaccines for children in America?

A federal judge has temporarily blocked the Trump administration from making big changes to vaccines for children in the United States. It is a blow to Health Secretary Robert F Kennedy - RFK Jr - a longtime vaccine sceptic who was given free rein by Donald Trump to “go wild with health”.

Since taking office a year ago, Kennedy has sought to slash the number of recommended shots for children from 17 to 11. The American Academy of Paediatrics and other large medical groups have sued, saying Kennedy's changes violate federal law and are based on ideology instead of science.

Marianna Spring and Justin Webb unpack what this means for Donald Trump’s big plan to - as he puts it - "Make America Healthy Again” with Dr Debra Houry, the former director of the CDC (Centre of Disease Control and Prevention) who resigned in August 2025.
