Shoddy work by a DNA-repair enzyme allows tuberculosis-causing bacteria to develop antibiotic resistance, scientists at the National Institute of Allergy and Infectious Diseases (NIAID) have discovered. Reported in the current issue of the journal Cell, the finding could lead to new ways to treat TB without risking the development of drug resistance.
HHS Secretary Tommy G. Thompson today announced the award of two contracts totaling up to $20 million in first-year funding to develop safer smallpox vaccines. The three-year contracts were awarded to Bavarian Nordic A/S of Copenhagen, Denmark, and Acambis Inc. of Cambridge, Mass. The National Institute of Allergy and Infectious Diseases (NIAID) will administer the contracts.
Like a well-trained soldier with honed survival skills, the common bacterium, Group A Streptococcus (GAS), sometimes can endure battle with our inborn (innate) immune system and cause widespread disease. By investigating the ability of combat-ready white blood cells (WBCs) to ingest and kill GAS, researchers have discovered new insights into how this disease-causing bacteria can evade destruction by the immune system. The research is being published this week in the Online Early Edition of the “Proceedings of the National Academy of Sciences, USA.”
A report of an individual infected with a second strain of HIV despite effective drug treatment following the first infection has researchers concerned. “For the first time, we’ve shown it is possible for an individual to become infected with two closely related strains of HIV,” says Bruce D. Walker, M.D., a researcher at Massachusetts General Hospital and Harvard Medical School. The findings underscore the challenges vaccine developers face in creating a broadly effective vaccine against HIV. The first HIV vaccines may not prevent infection altogether, but rather may prevent HIV from causing disease by limiting the virus’ ability to reproduce, explains Dr. Walker. This case shows that a hypothetical vaccine against one strain of HIV may not necessarily protect the vaccinee against other, closely related strains.
A pivotal efficacy trial of an experimental vaccine designed to prevent genital herpes in women began enrolling volunteers this week. The study will determine the vaccine’s ability to prevent genital herpes disease in women who are free of two common types of herpes simplex viruses (HSV): HSV-1 and HSV-2. The trial will eventually enroll 7,550 women in at least 16 sites in the United States.
Clinical tests began today of a novel vaccine directed at the three most globally important HIV subtypes, or clades. Developed by scientists at the Dale and Betty Bumpers Vaccine Research Center, part of the National Institute of Allergy and Infectious Diseases, the vaccine incorporates HIV genetic material from clades A, B and C, which cause about 90 percent of all HIV infections around the world. “This is the first multigene, multiclade HIV vaccine to enter human trials,” said NIAID Director Anthony S. Fauci, M.D. “It marks an important milestone in our search for a single vaccine that targets U.S. subtypes of HIV as well as clades causing the global epidemic.”
