Wild vs. lab rodent comparison supports hygiene hypothesis
In a study comparing wild rodents with their laboratory counterparts, researchers at Duke University Medical Center have found evidence that may help to explain why people in industrialized societies that greatly stress hygiene have higher rates of allergy and autoimmune diseases than do people in less developed societies in which hygiene is harder to achieve or considered less critical.

Use of a combination vaccine increased on-time immunization rates in infants
Results from a retrospective observational study of data among members of a managed care health plan in Utah showed that infants who received a combination vaccine had significantly higher rates of receiving all of their vaccinations on-time in the first two years of life compared to infants given separate component vaccines. Results from the study were presented today at the Academy of Managed Care Pharmacy's (AMCP) 18th Annual Conference in Seattle, WA, by Laura Happe, Pharm.D., M.P.H., associate director at Applied Health Outcomes, a research strategy company in Palm Harbor, FL. This study was conducted by Applied Health Outcomes.

Rotavirus vaccine will protect children against a major killer worldwide
The Food and Drug Administration (FDA) today announced the licensing of a new vaccine against a disease responsible for tens of thousands of hospitalizations in the United States and hundreds of thousands of deaths around the world each year. The vaccine, developed by Merck & Co., Inc., will be sold as ROTATEQ� and will protect infants against rotavirus infection. Rotavirus is a highly contagious virus that is the most common cause of severe dehydrating diarrhea in infants and young children.

Universal rules governing the way humans travel
Increasing human mobility is a key cause of the geographic spread of modern epidemics. Bacteria and viruses can be transported across great distances and transmitted to other people. In order to understand and predict the spread of disease, we need to know the statistical rules that govern human travel - in the light of an imminent flu pandemic a knowledge of great importance. Quantitative studies, however, prove to be very difficult, because people move over short and long distances, using various means of transportation (planes, trains, automobiles, etc.). Scientists from the Max Planck Institute for Dynamics and Self-Organization in G�ttingen, the University of G�ttingen, and the University of California, Santa Barbara, have found a trick to determine these rules. They had the idea of evaluating data from a popular US internet game in which participants can register a dollar bill for fun and monitor its geographic circulation. Like viruses, money is transported by people from place to place. Surprisingly, the scientist found that the human movements follow what are known as universal scaling laws. They developed a mathematical theory which describes the observed movements of travellers amazingly well over distances from just a few kilometres to a few thousand. The study represents a major breakthrough for the mathematical modelling of the spread of epidemics.

A solution to increase the efficacy of vaccines
Researchers have demonstrated a technique that has the potential to reduce the toxicity of vaccines and to make smaller doses more effective, according to a study published in PLoS Pathogens. Developing vaccines is fraught with challenges, particularly because many candidates carry a high risk of toxic side effects. For example, twenty percent of people immunized against smallpox will suffer side effects. Wilfred Jefferies, a researcher at the University of British Columbia and senior author of the study, and his colleagues have shown that boosting the production of TAP, an immune system component, can make smaller doses of vaccines more effective.

Needle-free immunizations
In a paper published today in Nature Reviews, "Immunization Without Needles," Mitragotri reviews in detail the characteristics � and pros and cons � of the currently available methods of immunization, which include topical application to the skin, pills, nasal sprays, injections, and others. Considerable advances have been made in the past decade, especially in transdermal (through the skin) and nasal immunization.
