Abstract
The Secretary of the US Department of Health & Human Services, Robert Kennedy Jr is leading a political agenda against vaccination. This is undermining the delivery of life-saving vaccination programmes and provision of evidence-based information on the safety and effectiveness of vaccines for the public and health professionals. Inconsistent and conflicting messaging between health practitioners and government health agencies erodes trust in public health programmes, creating a vacuum which is often filled with mis/disinformation that presents severe consequences for families. Due to the transnational spread of diseases, we consider the implications of events in the US for routine childhood vaccination programmes in the UK. Public health agencies across the world need to be 'Kennedy ready'; pragmatic steps must be taken to mitigate threats posed to vaccine confidence and the control of vaccine preventable diseases.
