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...

U.S. scientists say the discovery of a new mechanism of immunity suggests a more effective pneumococcal vaccine might be in the offing. Children's Hospital Boston and Harvard School of Public Health researchers say there might be a better way to protect people against Streptococcus pneumoniae infection. They said the current vaccine, Prevnar, is expensive and covers only 7 of the 91 known pneumococcal strains. Dr. Richard Malley and medical researcher Marc Lipsitch discovered that, in...
