Viruses - In Medicine

Transcript from "Viruses," National Center for Macromolecular Imaging
Vaccines are a second antiviral weapon. A vaccine introduced into the body gives it a clue about its attacker. Now the body can successfully fight the virus because it knows its chemical name. Smallpox no longer exists because of a vaccine. More than ten human vaccines have been created. Researchers are working to create vaccines for two of today's deadliest viruses, HIV and Rota. Rotavirus causes the dysentery that kills millions of children in underdeveloped countries. The relentless quality of these viral parasites is also an opportunity. Scientists are looking for ways to use viruses to deliver genetic fixes to cancer cells and to brain cells damaged by Alzheimer's.

Additional Virus information:
Rota Virus is the leading cause of gastroenteritis in children, adults, and elderly patients in nursing homes. The virus generally is contracted through contact with contaminated food or water. (U.S. National Library of Medicine. Viral gastroenteritis. NIH. Retrieved 03/12/2007 from
