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.

MIT researchers develop portable device to manufacture biopharmaceuticals on demand

For medics on the battlefield and doctors in remote or developing parts of the world, getting rapid access to the drugs needed to treat patients can be challenging. [More]
T-cell technology could be used to treat ovarian tumors with no adverse effects

T-cell technology could be used to treat ovarian tumors with no adverse effects

With only incremental improvements in ovarian cancer survival over the last 40 years, there is a clear need for new treatment options with long-lasting results. Many researchers have turned toward the development of immunotherapies that direct T-cells to selectively eliminate ovarian tumor cells, but an appropriate therapeutic target for ovarian cancers has remained elusive.

Penn researchers construct model to examine how immune system may evolve to conquer HIV

Penn researchers construct model to examine how immune system may evolve to conquer HIV

It has remained frustratingly difficult to develop a vaccine for HIV/AIDS, in part because the virus, once in our bodies, rapidly reproduces and evolves to escape being killed by the immune system. [More]
Scientists design and construct 10 large protein icosahedra to improve drug delivery

Scientists design and construct 10 large protein icosahedra to improve drug delivery

Using novel computational and biochemical approaches, scientists have accurately designed and built from scratch 10 large protein icosahedra--polyhedra with 20 faces--similar to viral capsids that carry viral DNA. [More]

WHO urges countries to take rapid action to reduce new infections, deaths from viral hepatitis

Ahead of World Hepatitis Day, 28 July 2016, WHO is urging countries to take rapid action to improve knowledge about the disease, and to increase access to testing and treatment services. [More]
Penn researchers develop plant-based oral vaccine booster

Penn researchers develop plant-based oral vaccine booster

Jonas Salk created a vaccine against polio that has been used since 1955; Albert Sabin created another version that has been on the market since 1961. Together, these two vaccines have nearly eliminated polio from the face of the earth. [More]
JAIDS presents important information to prevent HIV epidemic among transgender individuals

JAIDS presents important information to prevent HIV epidemic among transgender individuals

Programs to reduce the high risk of HIV infection among transgender people are urgently needed—but efforts are hindered by a lack of accurate information on HIV prevalence, HIV incidence, and specific risk factors facing this key population. [More]
Increasing rates of new HIV infections threaten 74 countries

Increasing rates of new HIV infections threaten 74 countries

AIDS deaths are falling in most countries worldwide, but the rate of new infections increased in several countries over the past decade, threatening to undermine efforts to end the AIDS epidemic by 2030, a new scientific paper shows. [More]
