Howard Hughes Medical Institute investigator William R. Jacobs and colleagues have produced a genetically altered strain of tuberculosis (TB) that elicits a stronger immune response than the current vaccine, bacillus Calmette-Guérin (BCG). The new vaccine improves survival of infected animals and may help put scientists on track to replace BCG, which has been used for nearly a century although it is largely ineffective.

Since the transmission of HIV and Hepatitis B virus (HBV) are so similar, individuals infected with one of these viruses are at a significantly increased risk for contracting the other.

Scientists at Johns Hopkins and elsewhere say they have mapped out an escape route that cancers use to evade the body’s immune system, allowing the disease to spread unchecked.

The first Australian trials of a vaccine developed by Queensland University of Technology that could save Australia's iconic koala from contracting chlamydia are planned to begin later this year.

Just under 150 Perth women have contributed to major international research at the Telethon Institute for Child Health Research that has proved that the new Cervarix vaccine provides broader protection against cervical cancer.

New Study Shows Hib Vaccine Protects Children From Significant Burden of Life-Threatening Pneumonia and Meningitis

- Study Shows Hib Vaccine Could Prevent About 1/3 of Life-Threatening Cases of Bacterial Pneumonia, the Leading Infectious Cause of Death in Asian Children

Researchers at the University of California, San Diego (UCSD) Skaggs School of Pharmacy and Pharmaceutical Sciences have patented a strategy for developing a human vaccine to prevent against Human Cytomegalovirus (hCMV) infection and disease.

A pair of new vaccines designed to combat cocaine and methamphetamine dependencies not only relieve addiction but also minimize withdrawal symptoms, according to study results presented today by Baylor College of Medicine (BCM) researchers at the Annual Meeting of the College on Problems of Drug Dependence in Quebec City, Canada.

Scientists have provided new details about how proteins used to destroy bacteria and viruses may help treat Alzheimer's disease. Gunnar K. Gouras, associate professor of neurology and neuroscience at Weill Medical College of Cornell University, New York, and colleagues provide new insights into how these proteins, called antibodies, reduce the main hallmarks of Alzheimer's disease and raise hopes for a vaccine against the disease.

New vaccines are available to make significant gains against cervical cancer deaths and debilitating pain from shingles, but infectious diseases experts warn that their full potential will not be realized without changes in the way vaccines for adults and adolescents are promoted, financed, and delivered in the United States.

New evidence supports the link between genetic factors and certain adverse events related to smallpox vaccination. The study, published in the July 15th issue of The Journal of Infectious Diseases, now available online, may have implications for predicting adverse events from other live vaccines.

More than seventeen million people in the United Kingdom, Germany, the Netherlands, Sweden, Denmark, Norway and Finland suffer from grass pollen induced allergic rhinitis. While symptomatic therapy has shown to be partially effective, a new tablet-based allergy vaccine GRAZAX(R) has shown to be both effective at symptom reduction and cost-effective.
