A first step to plant made dengue virus vaccines

Researchers have used plants to produce virus-like particles (VLPs) of the dengue virus in a potential first step towards novel vaccines against the growing threat.

A step toward a universal flu vaccine

Each year, the flu vaccine has to be redesigned to account for mutations that the virus accumulates, and even then, the vaccine is often not fully protective for everyone.

Vaccine ingredients could be hiding in small molecule libraries

Many vaccines include ingredients called adjuvants that help make them more effective by eliciting a stronger immune response. Identifying potential adjuvants just got easier, thanks to an approach described by scientists ...

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.
