HIV study revives vaccine hope

Posted in: HIV

In the United States, researchers have announced they have found two antibodies that may protect against strains of HIV currently circulating worldwide.

Moreover, this is detailed in a peer-reviewed journal. InScience (4 September) issue, a research paper explains that the two immune-system antibodies were found in the blood of an African patient who has HIV. The antibodies are may isolate a HIV organelle that is accessible and "conserved", meaning it does not mutate as the virus reproduces. This is the first new discovery in the area for over a decade.

As noted in a previous overview of ongoing HIVmicrobiological research, one key difficulty for antiviral vaccineresearch for HIV and any other virus is that viruses mutate over successive generations as they reproduce, thereby creating different strains.

An anti-HIV vaccineis not expected to appear within the intermediate future, and may not serve as a cure. But this news is conspicuous in an area of research that has yielded little other than new generations of drugs that slow the progress of HIV within HIV+ and people living with AIDS. Animal and human clinical trials may be needed to confirm the utility of this discovery.
