Immunotherapy Safety for the Primary Care ... - U.S. Coast Guard

Introduction
• “Anaphylaxis”
– Word first coined by Portier and Richet in 1902.
– While attempting to immunize dogs to sea anemone venom,
the dogs unexpectedly died after a previously non-lethal
dose.
– They had unwittingly sensitized the animals.
– This phenomenon was opposed to their goal of prophylaxis
so they referred to it as anaphylaxis, meaning “against
protection”.
