In 1956, a 14 year old girl named Linda Collins cut her finger and sought treatment at a local hospital in Turlock, California. Before receiving a tetanus shot, Linda received a small dose to check for any underlying sensitivity to the tetanus antitoxin. She was highly allergic to the tetanus antitoxin and nearly died as a result of the exposure. Her father, Dr. Marion Collins, who was away at the time on vacation, vowed that his daughter would never be vulnerable again. Linda, he insisted, would wear identification alerting health professionals to her condition. And MedicAlert was born.
