Apr 26, 1954: Polio Vaccine Trials Begin
On this day in 1954, the Salk polio vaccine field trials, involving 1.8 million children, begin at the Franklin Sherman Elementary School in McLean, Virginia. Children in the United States, Canada and Finland participated in the trials, which used for the first time the now-standard double-blind method, whereby neither the patient nor attending doctor knew if the inoculation was the vaccine or a placebo. On April 12, 1955, researchers announced the vaccine was safe and effective and it quickly became a standard part of childhood immunizations in America. In the ensuing decades, polio vaccines would all but wipe out the highly contagious disease in the Western Hemisphere.
MEMPHIS, Tenn. – A woman who spent nearly 60 years of her life in an iron lung after being diagnosed with polio as a child died Wednesday after a power failure shut down the machine that kept her breathing, her family said.
Dianne Odell, 61, had been confined to the 7-foot-long machine since she was stricken by polio at 3 years old.

Odell was afflicted with “bulbo-spinal” polio three years before a polio vaccine was discovered and largely stopped the spread of the crippling childhood disease.
She spent her life in the iron lung, cared for by her parents and other family members. Though confined inside the 750-pound apparatus, Odell managed to get a high school diploma, take college courses and write a children’s book.
The iron lung that she used was a cylindrical chamber with a seal at the neck. She lay on her back in the device with only her head exposed, and made eye contact with visitors using an angled mirror above her head. The lung worked by producing positive and negative pressure on the lungs that caused them to expand and contract so that she could breathe.
