Healthy 3 and 4-year-olds drive flu epidemics

Current immunization policies recommend universal flu vaccination for children aged 6-23 months, but shots are advised for older children only if they have high-risk medical conditions.

Clinical trials of daily oral antiretroviral dosing as pre-exposure prophylaxis

Writing in the journal Science, an international team of researchers, clinicians and others explains that a promising, relatively new approach is for people not infected but at high risk to take drugs that might prevent them from contracting HIV. But debate over the particulars of the strategy has slowed progress.

Flaviviruses immune system defenses in different ways depending on whether they are transmitted by mosquitoes or ticks

"Flaviviruses exact an enormous toll in terms of illness and death worldwide," notes NIAID Director Anthony S. Fauci, M.D. "Because this is a relatively new field of study, everything we learn about how these viruses operate is significant.

Chicken virus helps develop novel vaccines

Researchers at the University of South Australia are developing novel vaccines by using a chicken virus to either stimulate or suppress the body's immune system.

Dengue and other viruses may have developed tricks that let them reproduce inside macrophages

A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. Instead, the antibody somehow stops the infectious process at a later point.

Drug-releasing intravaginal ring could help prevent women from contracting HIV infection

The silicone vaginal ring steadily releases aciclovir: a treatment for genital herpes. It is known that women with genital herpes are at increased risk of HIV infection because the genital blisters caused by the infection increase the transmissibility of sexually acquired HIV.

Pain-free needles!

Millions of fearful patients could be saved the pain of vaccinations thanks to revolutionary pain-free needles to be revealed today for the first time at the British Pharmaceutical Conference in Manchester.

Cancer vaccine based on the bacterium Listeria monocytogenes, can cure mice with breast tumors

A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors. Cancer vaccines, which are more properly described as immunotherapy, work by boosting an immune response against tumor-associated antigens.

Antibody in humans that quickly fights the smallpox virus

Researchers at the La Jolla Institute for Allergy & Immunology (LIAI) have made a major advancement toward protecting society against a smallpox outbreak by identifying an antibody in humans that quickly fights the smallpox virus.

Researchers gain insights into how malaria pathogen destroys the cells in which it resides

By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides.

Vaccine candidate? Researchers synthesize oligosaccharide from anthrax pathogen

For weeks a white powder caused fear and shock for the American population: a few days after the attacks on September 11th, 2001, four innocent people became the victims of letters that contained the powder - spores of the anthrax pathogen. German researchers have now synthesized a molecule characteristic of anthrax in the laboratory which may be the basis for a new anthrax vaccine.

Increasingly virulent Staph infections

In a "Brief Report" in the 22 September 2005 issue of the New England Journal of Medicine, researchers at the University of Chicago describe three cases of rapidly progressive and ultimately fatal Staphylococcus aureus infections in small children.

Stopping UK BCG vaccination well justified

From autumn 2005, the long running routine programme to vaccinate school children against tuberculosis with BCG vaccine will stop. This decision brings the UK into line with much of the rest of the world and is well justified, writes Professor Paul Fine in the British Medical Journal (BMJ).

Researchers discover way to dramatically boost the output of immune system cells from the thymus

Mayo Clinic researchers have discovered a way to dramatically boost the output of immune system cells from the thymus, which may lead to improved cancer vaccines, as well as to ways to otherwise strengthen immune responses.

New technique may provide a better way of monitoring response to melanoma treatment

A new study published in PLoS Medicine describes a way to measure the immune response in people treated with an experimental vaccine to melanoma.

John Hopkins scientists uncover "tags" that force proteins to cell surface

Johns Hopkins scientists have discovered internal "shipping labels" that allow -- and perhaps force -- hundreds if not thousands of proteins to get to the surface of cells and stay there.

22 Sep 2005

Simple organism can produce 10 trillion varieties of a single protein

A team led by University of California, San Diego biochemists has discovered the mechanism by which a simple organism can produce 10 trillion varieties of a single protein, a finding that provides a new tool to develop novel drugs.

Drug that blocks acid buildup inside cells revs up the immune response to vaccines

Reporting in the current issue of The Journal of Experimental Medicine, Vincenzo Barnaba and his team at the University of Rome show that people receiving booster shots against hepatitis B virus developed more robust immune responses if given a widely used anti-malaria drug called chloroquine.

Vaccine against group B streptococcus

Common bacteria that live harmlessly in the gastrointestinal tract and vagina of 25 percent of women can become lethal if a newborn gets exposed to them during birth.

Healthcare workers show general apathy towards the flu vaccination

Low flu vaccination rates among healthcare workers could be risking the lives of frail elderly patients and increasing winter pressures in UK hospitals, according to research published in the latest issue of Journal of Clinical Nursing.
