The MedicAlert Foundation first launched in Turlock, California, in 1956, before coming to the UK over 55 years ago. As the pioneers of medical IDs, we remain the only charity provider of life-saving medical ID services worldwide. MedicAlert UK is based in Buckinghamshire, with a production unit creating bespoke medical ID jewellery and a member services team including in-house Registered Nurses to support our 42,000 members. At 14 years old, Linda Collins cut her fingers while out shooting in Turlock, California, USA. During treatment, she was given a skin test for a dose of tetanus antitoxin and went into near-fatal anaphylactic shock. Luckily, she survived. However, if Linda had been given a full dose, she may not have survived. Her parents, Dr Marion and Chrissie Collins, now more aware of Linda’s vulnerability, would attach a note to her coat describing her allergies. When Linda started university, they wanted something more permanent so they designed a metal disc showing the Rod of Asclepius (the Greek symbol for healing - the familiar sword with a snake wrapped around it) and 'MedicAlert' in red. On the back were details of Linda's allergies.
