Human Trials Have Begun Of The New AIDS Vaccine

A new study published in the journal Science revealed a new AIDS vaccine. Scientists claim that they have discovered a new AIDS vaccine, The vaccine was tested on non-human primates and the results revealed that in half of them the vaccine was able to completely prevent HIV infection.

The monkeys were first injected with the vaccine and then injected with SIV (simian immunodeficiency virus), which is similar to HIV. A total of six injections were given to the monkeys in order to establish the resistance factor up till which the vaccine sustains.

Scientists are very hopeful with this new discovery of the AIDS vaccine because the study proved the results of the combination of high exposure rates and the number of monkeys that did not get sick.

Human trials have already begun by Johnson & Johnson. The human trial study consists of 400 patients from Thailand, South Africa, East Africa and the U.S.

The last human trials for an AIDS vaccine were conducted in 2007, after that scientist have been at a roadblock.

If the results from this small human trail prove fruitful than a larger clinical trail with humans would begin in the next two years.

The new AIDS vaccine consists of two steps; first the participants are injected with weakened cold virus, this allows the entry of HIV genes into the body. The second step is to give the participants a very pure from of an HIV surface protein, this causes the body’s immune system to strongly react to the invader.

Dr. Mary Marovich, who directs the vaccine research program at the National Institute for Allergy and Infectious Diseases, was very cautious about the new AIDS vaccine and felt that the results were not impressive. She went on to add that it would be a major accomplishment even if half the participants in the human clinical trial were protected from the exposed virus.

Scientists have been studying and working on an AIDS vaccine for over 30 years and have spend millions of dollars into the effort.

35 million people are suffering from this disease worldwide, out of those 35 million, 3,2 million are children who have been infected at birth by being born to HIV positive mothers.

Janssen is the company behind this new AIDS vaccine, the vice president of Janssen, Hanneke Schuitemaker, commented on the future saying, “The Company recognizes that the future is in prevention and that we really should work on vaccine that can prevent infectious disease.”
