It is known that HIV-infected children who do not receive appropriate antiretroviral drugs experience immune depression, and may become susceptible to infectious diseases that would otherwise be prevented by childhood immunization. view more (2007-12-05)
Malaria may fuel spread of HIV in sub-Saharan Africa
Malaria may be fueling the spread of HIV in areas of sub-Saharan Africa where there is a substantial overlap between the two diseases, while HIV may be playing a role in boosting adult malaria-infection rates in some parts of the region, according to a new study by researchers at Fred Hutchinson Cancer Research Center and the University of... view more...

NIAID media availability: New strategy proposed for designing antibody-based HIV vaccine
Most vaccines that protect against viruses generate infection-fighting proteins called antibodies that either block infection or help eliminate the virus before it can cause disease. view more (2009-06-15)
Smokers may be at greater risk of HIV infection

Study finds strong demand for HIV meds after high-risk sex
People who do not have HIV but seek antiretroviral medications following high-risk sexual encounters are very likely to complete the full monthlong drug regimen, according to a new UCLA AIDS Institute study. Moreover, there is a strong demand for publicly available post-exposure prophylaxis among high-risk populations in Los Angeles County. view more (2007-11-09)
Antiretroviral Therapy Effective In Reducing Mother-to-child HIV-1 Transmission When Started After Childbirth (p 1171)
Results of a study from Malawi in this week's issue of THE LANCET highlight how antiretroviral therapy targeted at babies soon after childbirth (because their mothers' HIV diagnosis was made around the time of delivery) is still effective in preventing vertical HIV-1 transmission from mothers to their children. Zidovudine and nevirapine have been... view more... (2003-10-08)
New study debunks misconceptions about barriers to the CDC's HIV testing recommendations

Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. view more (2005-10-14)
Well-armed immune cells help long-term nonprogressors contain HIV
