A combination of two vaccines - one genetically-derived - has proved effective against HIV in human clinical trials.
While not claiming complete success, US National Institute of Health researchers says the vaccines, administered in combination, produced good results, especially the one that was DNA-based. It was found to be "safe and well-tolerated," according to a news release from the Infectious Disease Society of America.
Two problems still exist, the scientists say. The DNA-based vaccine is less potent than other anti-Aids immunisations, and the other vaccine may be subject to some outside influence.
The findings are published online in the December 15 issue of The Journal of Infectious Diseases. – (HealthDayNews)
