Researchers create a better way to transport life-saving vaccines

Researchers at McMaster University have invented a stable, affordable way to store fragile vaccines for weeks at a time at temperatures up to 40C, opening the way for life-saving anti-viral vaccines to reach remote and impoverished ...

New single vaccination approach to killer diseases

Scientists from the University of Adelaide's Research Centre for Infectious Diseases have developed a single vaccination approach to simultaneously combat influenza and pneumococcal infections, the world's most deadly respiratory ...

New HIV vaccine strategy 'pumps' the immune system

A new HIV vaccine delivery strategy appears to enhance the protective immune response in a preclinical model. Scientists at the La Jolla Institute for Immunology (LJI) have discovered that delivering an HIV vaccine in small ...

New approach could lead to a lifetime flu vaccine

If the virus that causes flu were an ice cream cone, then the yearly vaccine teaches the immune system to recognize just the scoop – chocolate one year, strawberry the next. As the virus changes each year, so too must the ...

Scientists find another way HIV can hide from vaccines

A Yale-led team has discovered yet another molecular trick HIV uses to survive immune system attacks, a finding that may influence efforts to develop an effective vaccine against HIV/AIDS.

Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains a small amount of an agent that resembles a microorganism. 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.

Vaccines can be prophylactic (e.g. to prevent or ameliorate the effects of a future infection by any natural or "wild" pathogen), or therapeutic (e.g. vaccines against cancer are also being investigated; see cancer vaccine).

The term vaccine derives from Edward Jenner's 1796 use of the term cow pox (Latin variolæ vaccinæ, adapted from the Latin vaccīn-us, from vacca cow), which, when administered to humans, provided them protection against smallpox.
