En eksperimentel ny AIDS-vaccine viser sig kun at være effektiv i meget kort tid, ifølge forskere, der har fundet det vanskeligt at forklare, om lægemidlet faktisk er nyttigt. Dr. Nelson Michael, oberst ved Walter Reed Army Research Institute of Research i Maryland, og hans team observerede kun en mindre, tidsmæssig fordel hos patienter, der tog vaccinen, efterfulgt af et fald i effektiviteten.

Den eksperimentelle vaccine er en kombination af Sanofi-Pasteurs ALVAC canarypox/HIV-vaccine og VaxGen's AIDSVAX. Efter at AIDSVAX viste sig at være ineffektiv i 2003, besluttede forskerne at kombinere det med ALVAC for at se, om denne kombination ville fungere. Tidlige resultater syntes at vise, at vaccinen reducerede risikoen for at blive inficeret med AIDS med 31 procent. I løbet af et år syntes risikoniveauet imidlertid at vende tilbage til det normale.

På konferencen om retrovirus og opportunistiske infektioner i San Francisco forklarede holdet, at de muligvis kunne komme med en ny undersøgelse for at verificere legitimiteten af ​​vaccinen. Dr. Michael sagde, at han planlægger at samarbejde med Dr. Anthony Fauci fra U.S. National Institute of Allergy and Infectious Diseases for at udvikle nye forsøg, der skal gennemføres i Asien eller Afrika.

It is important to note that studies conducted on vitamins and nutrients showing positive results are usually accompanied with disclaimers by researchers that further study is needed to verify the results. In this case, researchers have been working overtime to defend the legitimacy of the experimental AIDS vaccine trial, despite the fact that they admit the results are questionable and they cannot determine whether it was actually a success.

The team plans to follow up the study by evaluating blood samples from vaccinated participants to measure their antibody levels. They hope to find evidence that the vaccine is exerting some kind of influence on participants' immune systems.

Previous AIDS vaccines have all proven to be a failure. In 2008, two of the most viable options gathered from a 20-year search not only failed to provide protection from the disease but actually increased one's risk of becoming infected with AIDS.

Since its first discovery in the 1980s, it is estimated that roughly 25 million people have died from AIDS. Various combinations of pharmaceutical drugs are offered to AIDS patients to help control the disease, but according to mainstream experts, there is no cure for it.
