Of the two major types of HIV, only one, HIV-1, typically causes AIDS in infected people who don't receive treatment. A study published by Cell Press November 21st in the journal Immunity reveals how HIV-1 escapes detection by essentially becoming invisible to a patient's immune system, whereas HIV-2 triggers protective immune responses in patients. This understanding of how HIV-1's ”invisibility cloak” works could lead to the development of effective vaccines against HIV-1.

A new analysis of two HIV vaccine trials that involved pediatric patients shows that the investigational vaccines stimulated a critical immune response in infants born to HIV-infected mothers, researchers at Duke Medicine report.

An Atlanta research collaboration may be one step closer to finding a vaccine that will provide long-lasting protection against repeated exposures to human immunodeficiency virus (HIV). Scientists at Emory University and GeoVax Labs, Inc. developed a vaccine that has protected nonhuman primates against multiple exposures to simian immunodeficiency virus (SIV) given in three clusters over more than three years. SIV is the nonhuman primate version of HIV.

Scientists from the Antwerp Institute of Tropical Medicine, Antwerp University Hospital and Antwerp University have tested a new ‘therapeutic vaccine’ against HIV on volunteers. The participants were so to say vaccinated with their own cells. The researchers filtered certain white blood cells out of the volunteer’s blood, ‘loaded’ them outside the body and then gave them back. The immune system of the testees was better than before in attacking and suppressing the virus, the scientists reported in the top journal AIDS. But they still cannot cure the disease.

New vaccine research suggests that scientists are homing in on the critical ingredients of a protective HIV vaccine and identifies new HIV vaccine candidates to test in human clinical trials. The new findings appear online in the journal Nature on January 4, 2012.

Researchers have found a way to prevent HIV from damaging the immune system, in a new lab-based study published in the journal Blood. The research, led by scientists at Imperial College London and Johns Hopkins University, could have important implications for the development of HIV vaccines.
