Biological differences between the sexes could be a significant predictor of responses to vaccines, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They examined published data from numerous adult and child vaccine trials and found that sex is a fundamental, but often overlooked predictor of vaccine response that could help predict the efficacy of combating infectious disease. The review is featured in the May 2010 issue of The Lancet Infectious Diseases. "Sex...

New research may guide creation of targeted, more effective vaccines A new understanding of a certain cell in the immune system may help guide scientists in creating better flu vaccines, report researchers from the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children's Hospital Boston (PCMM/IDI). Reporting online March 21 in Nature Immunology, they show, for the first time, that white blood cells known as resident dendritic cells (DCs) capture flu viruses...

ROCHESTER, N.Y., Nov. 27 /PRNewswire-USNewswire/ -- Preventing disease is the goal of every health care provider and fortunately every year, new vaccines are being added to assist in disease prevention. But do all vaccines boost immunity for the same period of time? And, if not, when are additional 'booster shots' needed to keep immunity strong? In this month's issue of Pediatrics, the Journal of the American Academy of Pediatrics, Michael Pichichero MD, Director of the Rochester...

Immunity to whooping cough lasts at least 30 years on average, much longer than previously thought, according to a new study by researchers based at the University of Michigan and the University of New Mexico. Details are published October 30 in the open-access journal PLoS Pathogens. Once thought to be under control following widespread childhood vaccination, whooping cough (pertussis) has been on the rise since the 1980s in the United States and several other countries. Several explanations...

Patients with the autoimmune disease systemic lupus erythematosus (SLE) have an increased risk of infection, due to both disturbances in their immune responses and treatment with immunosuppressive drugs. Because morbidity and mortality related to influenza are increased in immunocompromised patients, it is recommended that patients with SLE get annual flu shots, which are safe and do not increase disease activity. Both antibody and cell-mediated responses are involved in the immune response...

New research suggests that a common immunosuppressive drug may have the ability to boost the power of vaccines, BBC News reported. The drug rapamycin is commonly given to transplant patients to stop their bodies rejecting donor organs, but scientists at Emory University discovered during tests on mice and monkeys that it enhanced the response of their immune system to experimental vaccines. The study also raises hopes of a new generation of potent vaccines. According to the research published...

Children adopted from countries such as Russia, China and Guatemala may not be protected against polio, measles or other diseases despite records indicating they have been immunized, according to a report in the May issue of Archives of Pediatrics & Adolescent Medicine, a theme issue on vaccines. U.S. families have adopted almost 250,000 foreign-born children in the last 15 years, according to background information in the article. Many of these children were living in orphanages or other...

A U.S. study suggests amphibians might be able to develop immunity to the fatal fungus disease that is reducing the Earth's amphibian populations. Jonathan Richmond of the U.S. Geological Survey and colleagues said they discovered individual amphibians can develop both acquired and innate immunity to the fungal disease chytridiomycosis, which is caused by the fungus Batrachochytrium dendrobatidis. The researchers said scientists should broaden their studies of chytridiomycosis to include...

Australian scientists say a bird flu vaccine is closer to reality thanks to their finding that boosting T-cell immunity can protect humans from the disease. The 'Killer T cell' is the hit-man of the immune system, said University of Melbourne Professor Stephen Turner, lead author of the research. It is able to locate and destroy virus-infected cells in our body helping rid us of infection. Unfortunately, current influenza vaccines are poor at inducing killer T cell immunity. Therefore, we...

In the first study of its kind, researchers at the Yerkes National Primate Research Center and Emory Vaccine Center, Emory University, have developed a multidisciplinary approach involving immunology, genomics and bioinformatics to predict the immunity of a vaccine without exposing individuals to infection. This approach addresses a long-standing challenge in the development of vaccines--that of only being able to determine immunity or effectiveness long after vaccination and, often, only...
