(NaturalNews) An experimental new AIDS vaccine is proving to be effective for only a very short time, according to researchers who have been finding it difficult to explain whether or not the drug is actually useful. Dr. Nelson Michael, a colonel at the Walter Reed Army Research Institute of Research in Maryland, and his team observed only a minor, temporal benefit in patients who took the vaccine, followed by a decline in efficacy.
The experimental vaccine is a combination of Sanofi-Pasteur’s ALVAC canarypox/HIV vaccine and VaxGen’s AIDSVAX. After AIDSVAX was found to be ineffective in 2003, researchers decided to combine it with ALVAC to see if that combination would work. Early results appeared to show that the vaccine reduced the risk of becoming infected with AIDS by 31 percent. However within a year, the risk level seemed to return back to normal.
