A pioneering cancer expert described by the Duke of Cambridge as an “inspiration” died suddenly yesterday after a routine inoculation for yellow fever.

Martin Gore, 67, suffered total organ failure soon after having the jab, which is recommended for travellers to parts of Africa, the Caribbean and South and Central America. His death highlights the increased risks associated with the vaccine for the growing number of older travellers visiting exotic destinations.

The doctor was a professor of cancer medicine at the Royal Marsden NHS foundation trust and the Institute of Cancer Research in London.
