Human Test: Novel Vaccine Stops HIV: "Human Test: Novel Vaccine Stops HIV
Treatment Turns On Anti-HIV Immunity, Holds AIDS Virus in Check
By Daniel DeNoon - WebMD Medical News
Nov. 29, 2004 -- It worked in mice. It worked in monkeys. And now in humans, a therapeutic vaccine has stopped HIV in its tracks.
The vaccine is made from a patient's own dendritic cells and HIV isolated from the patient's own blood. Dendritic cells are crucial to the immune response. They grab foreign bodies in the blood and present them to other immune cells to trigger powerful immune system responses to destroy the foreign invaders.
HIV infection normally turns these important immune system responses off. But animal studies show that when dendritic cells are 'loaded' with whole, killed AIDS viruses, they can trigger effective immune responses that keep infected animals from dying of AIDS.
Wei Lu, Jean-Marie Andrieu, and colleagues at the University of Paris in France and Pernambuco Federal University in Recife, Brazil, tested the vaccine on 18 Brazilian patients. All had HIV infection for at least a year. Their T-cell counts -- a crucial measure of AIDS progression -- were dropping, meaning their disease was worsening. None was taking anti-HIV medications.
After getting three under-the-skin injections of the tailor-made vaccine, the amount of HIV in the patients' blood (called the viral load) dropped by 80%. After a year, eight of the 18 patients still had a 90% drop in HIV levels. All patients' T-cell counts stopped dropping.
The findings appear in the December issue of Nature Medicine.
'The results suggest that [these] vaccines could be a promising strategy for treating people with chronic HIV infection,' Andrieu and colleagues write. 'The significant decrease of viral load as well as maintenance"

IS THIS VACCINE WORKS ONLY FOR HIV-1 OR HIV-2 AS WELL ? OTHER WISE
IF EVEN THIS NOVEL VACCINE SUCCED IT LEAVE HIV-2 INFECTED PEOPLE WITHOUT HOPE --- ANYWAY IT SEEMS SCIENTIST(S) CLOSE TO WIN HIV AND HIV WILL END FOREVER!!!!!!
