What health breakthrough was discovered in the year you were born?
Breakthrough: Varicella virus vaccine was licensed for the active immunization of persons 12 months of age and older.
Description: Varicella virus causes chickenpox, which is a highly contagious disease that lasts about two to three weeks. The Food and Drug Administration estimated that the vaccine was 70 to 90 percent effective at preventing the disease.
Breakthrough: The sheep, Dolly, became the first mammal cloned from an adult cell.
Description: Dolly the sheep was cloned by scientists Sir Ian Wilmut, Keith Campbell and their colleagues at the University of Edinburgh in Scotland. She lived to be six years old.
Breakthrough: Nobel Prize awarded for the discovery of prions, a new biological principle of infection.
Description: Prion diseases are a rare group of progressive neurodegenerative diseases that affects both humans and animals. One such disease is mad cow disease, which is called Creutzfeldt-Jakob in humans.
Breakthrough: First vaccine for Lyme disease created.
Description: This vaccine, given in three doses, was 78 percent effective at preventing lyme disease. However, more than 90 percent of cases were found in only 10 states. In 2002, the creators of the vaccine withdrew it from the market and did not apply for a license.
Breakthrough: Nobel Prize awarded for the discovery that proteins have intrinsic signals that govern their transport and localization in the cell.
Description: Proteins are constantly made within our cells and transported out to do essential functions. Biologist Günter Blobel discovered the intrinsic signals and molecular mechanisms by which the proteins are transported.
Breakthrough: First draft of human genome announced.
Description: The Human Genome Project’s assembly of a working draft of the sequence of a human genome in 2000 was an important development because the genome is the genetic blueprint for a human being. It has already helped scientists pinpoint many genes related to diseases.
