Traveling with children—whether for a holiday or a permanent move—comes with unique health challenges. To better understand how families can prepare, we spoke with Dr. Natalie Prevatt, a Consultant Paediatrician and expert in travel and tropical medicine. Dr. Prevatt trained in London and at the Hospital for Tropical Diseases, and she has worked across Africa and the Pacific. She now runs NHS clinics in infections and immunity, and a remote travel clinic, The Children's Travel Doc, focused on children and pregnant women. As Chair for Paediatrics at the International Society of Travel Medicine, she helps shape global travel health guidance. In this interview, she shares essential advice on vaccinations, illness prevention, and planning for both short trips and long-term relocations.
