Germ warfare: the battle for the key to modern vaccines

In the late 1960s the scientist behind the world's most successful antiviral vaccines took on his employer and the US government in a fight for custody of the cells that he called his 'children'

On 9 October 1964, a baby girl was born at Philadelphia general hospital. She arrived early, when her mother was about 32 weeks pregnant. The baby weighed 3.2lb and was noted to be blue, floppy and not breathing. The only sign of life was her slow heartbeat. Nonetheless, she clung on, and her 17-year-old mother named her.

One month later, the baby was still in the hospital, and a doctor listening with a stethoscope heard a harsh heart murmur. A chest X-ray showed that she had a massively enlarged heart because a hole in the organ was preventing it from pumping blood efficiently. It also emerged that the baby had cataracts blinding both eyes. Later, other signs indicated that she was profoundly deaf.
