Researchers at the University of Rochester Medical Center are testing a new oral vaccine to prevent infection with HIV, the virus that causes AIDS. The vaccine is unique because it is given as a pill, unlike most HIV vaccines tested to date that have been given as shots.
Researchers at Columbia University’s Mailman School of Public Health have found that an injection of antiretroviral drugs can give 100 percent protection from HIV.
Monkeys were injected with the drugs in two separate trials, with protection lasting a month. However, research suggests that such an injection could last for up to three months, reports the New York Times.
Viral load suppression means risk of HIV transmission is ‘at most’ 4% during anal sex, but final results not due till 2017
A low CD4 cell count is associated with increased mortality risk, even if people are taking virologically effective HIV therapy, an international team of investigators report in the online edition of Clinical Infectious Diseases. People with incomplete CD4 count recovery – a count below 200 cells/mm3 – despite three years of treatment with virologic suppression had a more than two-fold increase in their mortality risk compared to people with more robust immune reconstitution.
