New vaccine against whooping cough is effective in teens and adults

The Journal of the American Medical Association (JAMA) has announced that a study to be published in the June 22/29 issue found that a new vaccine against whooping cough is effective in teens and adults, carriers of the contagious respiratory disease so dangerous to infants.

Stronger version of chickenpox vaccine cuts incidence and severity of shingles in older adults

In one of the largest adult vaccine clinical trials ever, researchers have found that an experimental vaccine against shingles (zoster vaccine) prevented about half of cases of shingles--a painful nerve and skin infection--and dramatically reduced its severity and complications in vaccinated persons who got the disease. The findings appear in the June 2 issue of The New England Journal of Medicine.

Blood abnormality, sickle cell trait, gives added protection to children from malaria

The blood cell abnormality, sickle cell trait, gives an increasing amount of protection against malaria as young children grow during their first ten years of life, new research has revealed.

Sickle cell protects against malari

In this month's issue of the open access journal PLoS Medicine, Dr. Thomas N. Williams and colleagues from Kilifi, Kenya, show that the protection against malaria given by carrying the gene for sickle cell haemoglobin may involve the immune system.

Leprosy microbes lead scientists to immune discovery

With the unusual opportunity that human leprosy infections provide for study of human immune responses, scientists have discovered how the body's early warning system prompts a rapid immune response by two separate armies of defensive cells.

Is winter flu worse because of exercise-induced 'window of susceptibility'?

When you exercise or work outside in winter, that dry feeling at the back of your throat indicates the cold air has irritated your throat. Racehorses share a similar experience: exercising in below-freezing air causes mild airway injury.

Stimulating innate immunity helps ease Crohn's disease symptoms

Like throwing oil on a fire or prescribing a high cholesterol diet for heart patients, gastroenterologists traditionally have believed that it would not be a good idea to stoke up the body's immune system to treat Crohn's disease.

Human cells can silence an essential part of HIV's genetic make-up

For the first time, scientists have shown that humans use an immune defense process common in plants and invertebrates to battle a virus.

New combination vaccine effective against plague

Plague, a bacterium that ravaged Europe in the Middle Ages and is today one of the most feared potential agents of bio-terrorism, may have met its match, according to Wake Forest University School of Medicine scientists.

Nutrition gene key in regulating immune system

A gene that signals a yeast cell to make bread rise and mice to eat a better diet also helps selectively silence the immune system, researchers have found.

Scientists have uncovered a new method the immune system uses to label foreign invaders as targets to be attacked

Researchers showed that the immune system can brand foreign proteins by chemically modifying their structure, and that these modifications increased the chances that cells known as lymphocytes would recognize the trespassers and attack them.

Intralesional immunotherapy for common warts is effective and safe

Injection of skin test antigens (preparations used in skin tests for immunity) into warts appears to stimulate the immune system and successfully treat the injected wart and also helps to treat distant non-injected warts, according to a study in the May issue of Archives of Dermatology.

Six million doses of polio vaccine shipped to Yemen

Six million doses of monovalent oral polio vaccine type 1 (mOPV1) have been shipped to Yemen, as part of emergency measures to stop the ongoing polio outbreak in the country.

Vaccine developed at Rockefeller University boosts natural killer T cells in patients with cancer

A new vaccine designed at The Rockefeller University boosted a type of fast-responding immune system cell called the natural killer T (NKT) cell in patients with advanced cancer. The study surprised researchers by revealing the ability of these NKT cells to spur other, slower-responding immune cells to go to work.

Whooping cough makes a comeback

The latest comeback in the health arena is whooping cough and experts are sufficiently concerned for the US government to approve the first whooping cough booster shot meant just for adolescents. The shot will be added to a booster shot against two other diseases, tetanus and diphtheria, that children already get sometime between ages 10 and 18.

College freshies show weaker immune responses

Being a college freshie may have more ramifications than being lonely and missing Mum's cooking, according to a new study at Carnegie Mellon University in Pittsburgh which shows that first-year students had a weaker immune response to the flu shot than did other students, and confirms suspicions that going to college challenges both mind and body.
