Their method makes use of nanopatches, which are fingernail-sized dermal patches with microscopic projections on their surface that hand vaccine off directly to the antigen-presenting cells just below the surface of the skin. The scientists’ recent work in mice has shown that an immune response equivalent to that achievable by needle and syringe can be reached using 100 times less vaccine. Not only does the nanopatch appear to be a more effective delivery method, it’s also cheaper to produce and doesn’t require refrigeration, adjuvants or multiple doses.

But that may not be such a good idea, according to a new study published in Lancet. Giving infants Tylenol (generic – paracetamol) to prevent fever after a vaccination may reduce the vaccine’s effectiveness, a new research has found. Parents usually give Tylenol before or immediately after a routine shot so the child does not get a fever. However, this may not be a good idea since fever is usually the body’s natural immune response to the vaccine. In a Czech study published in Lancet (online October 16), 459 infants were followed after routine vaccination against polio, pneumonia, meningitis, whopping cough, tetanus and other childhood diseases. Half of the babies were given paracet...

Psoriatic patches, which are usually itchy and painful, are inflamed areas where excessive layers of cells had built up on the skin. And now, after extensive and extended testing, the FDA has approved ustekinumab (Stelara) for moderate to severe plaque psoriasis. (See amazing before-and-after photos!) Psoriasis is an auto-immune disease, which means a faulty immune system mistakenly attacks the skin and joints, treating the body like an invader and releasing chemicals that otherwise fight infections and foreign substances. As bad as it already looks, psoriasis affects more than the skin. The dis...

From the Scientific American story:The much-ballyhooed human embryonic stem cell apparently may share a problem with transplanted organs: a high probability of rejection.Researchers at Stanford University School of Medicine found that mice mounted an immune response after being injected with human embryonic stem cells (hESCs). The result: all the transplanted stem cells--which hold the promise of maturing into several different types of tissue--were dead within a week.Wu says that the fact that the hESCs could not survive in the mouse, coupled with previous work showing that the animals also reject mice...

It is a classic warfare of measure/counter-measure, not unlike modern warfare. But unlike human warfare, a successful parasite is not the one that kills its host—that would spell  the demise of the parasite; that would be self defeating, won't it? Success is defined as the capacity to live off the host, and efficiently spread to other individuals. The host, on the other hand, is successful if it can avoid being killed by the attack and keep the attacker in check. And so we can see a battle of adaptations: a parasite honing its “skills” so as to attack, but not kill...

The body's reaction to infection from the flu virus or even strep in pregnant woman and their unborn children may play a role in the development of schizophrenia, obsessive compulsive disorder, autism and other brain diseases. "More than 200 studies have suggested that schizophrenia occurs between 5 and 8 percent more frequently than average in children born in the winter or spring. Scientists realized that viruses, which are most prevalent in the cold, dry winter months, could be one of the factors influencing this correlation. In 2004 Alan S. Brown, a psychiatrist at Columbia University, analyzed blood samples collected from 1959 through 1966 from 189 pregnant women, 64 of whom ha...

He vaccinated a boy against smallpox by pricking his arms with pus taken from the sores of a milkmaid with cowpox, a closely related but milder disease. He based this audacious experiment on his astute observation that milkmaids, who had been exposed to cowpox, never contracted smallpox. Let’s not forget what smallpox meant in those days—it meant an almost 100% chance of death. Could anybody have guessed that this observation would become the first harbinger of the field of Immunology? It took over 200 years before another vaccine was created; in 1914 a vaccine against whooping cough was introduced. But t...
