Vaccine News and Research RSS Feed - Vaccine News and Research

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Researchers find new way to target deadly virus and develop vaccines

Researchers find new way to target deadly virus and develop vaccines

Venezuelan equine encephalitis virus (VEEV) is an unforgiving killer of horses, donkeys and zebras, resulting in mortality as high as 80 percent of infected animals. It causes rapid, catastrophic swelling of the brain and spinal cord, leading to severe neurological symptoms and--in many cases--sudden death. [More]
