The Anaphylaxis Campaign visit historic yacht at the European Academy of Allergy and Clinical Immunology (EAACI) conference at London’s Excel

About 100 years ago, anaphylaxis was discovered on a yacht like the one pictured. The Prince of Monaco had asked two French doctors, Portier and Richet, to develop a vaccine against Portuguese Man-o-War venom, as his subjects were being stung when swimming. He lent them his yacht for the expedition. The injections of venom vaccine, far from protecting the experimental dogs, were lethal when injected a second time at a certain interval. The doctors realised that this was the opposite of prophylaxis and coined the term ANAphylaxis - and were awarded the Nobel Prize for Physiology or Medicine in 1913.

The yacht is seen here moored on the River Thames outside the Excel centre at the EAACI conference in June and The Anaphylaxis Campaign seemed to be fitting guests on such a boat after hearing the tale of how the term anaphylaxis was coined.

The Chief Executive (Lynne Regent) and President (Dr Bill Frankland) of The Anaphylaxis Campaign are pictured on board the historic yacht with experts in the field of allergy.
