amigoro writes with the happy news that a possible vaccine against HIV is nearing readiness for clinical trials. The compound could provide a 'double whammy' by not only inoculating the patient against future infection, but destroying an HIV infection in progress. "The vaccine is an artificial virus-like particle whose outer casing consists of the TBI (T- and B cell epitopes containing immunogen) protein constructed by the researchers combined with the polyglucin protein. This protein contains nine components stimulating different cells of the immune system: both the ones that produce antibodies and the ones that devour the newcomer."

Re: (Score:3, Interesting)
It is possible to have HIV without having full-blown AIDS (the qualification for the disease is to have a certain quota of viral particles in a sample of your blood.)
The definition of AIDS is having all the associated symptoms and being HIV positive. This is what I mean by HIV and AIDS being associated only by definition. If someone has all the symptoms of AIDS, CD4+ T Lymphocyte count, but is not HIV positive then they are not labeled as having AIDS. This has only been true since the acceptance of the link between HIV and AIDS.

That sucks. What about all the people with Aquired Immunodeficiency Syndromes from other causes? There are chemicals that can do it, and many other causes as well. Now that the definition of AIDS has been modified, do these people no longer have Aquired Immonodeficiency Syndromes? They're all healthy and OK now?
Furthermore, if that's all AIDS means anymore, why do we even need the term? For other infections, we don't have a separate name. If you are infected with tuberculosis and then start coughing, we don't change the description to Aquired Coughing Syndrome (ACS).

Mutation can be caused by a number of processes, including transcription errors in mitosis, radiation, retroviral infection, etc. After mutation you have a member of a species with slightly different abilities to the others. If this difference confers a survival advantage (or, more accurately, a mating advantage), then it will be passed on a lot, and result in the majority of the species possessing the advantage.Parent

Considering the extent to which pharmas withhold treatment from dying people, (backed by WTO threats, patent manipulation, WIPO lobbyists, etc) I'd say it's quite obvious they could be classified as total sociopaths.
And really, a vaccine, or a cure, for AIDS would be a short-lived media bonus; when was the last time you heard anything about whatever companies created various vaccines (apart from allegations of causing things like autism, or for needlessly encouraging tax-financed and uncessary vaccinations)?
The thing is, if you analyze it, the entire economy of patent incentives is based on the ability to _deny_ everyone the right to produce a certain substance. The worse the consequences, the higher the price can go. Patents dont generate a lot of money for curing or preventing disease; they generate the maximum level of revenue when they set the price so high that they _deny_ a certain subset of customers access, and deny that subset of customers the right to buy the medicine from anyone else. (And please, dont give me the 'but they need the money to research' crap; the money is largely wasted on marketing, administration and inefficient production; we'd get five times the research for what we're paying today if we outright just paid for it and scrapped medical patents).
The very foundation of the system is so ethically corrupt that it's no wonder the pharmas are the way they are.
Personally I dont doubt for a second that they'd simply bury any substance (reorganize, change strategic direction) that appeared to actually have a chance at curing something they were selling a symptom treater for.

I think not.
Not everyone who gets AIDS can afford drug therapy. The vast majority of new infections in 3rd world countries will most certainly not engage in treatment. Drug companies are only making money off "daily regiments" by bleeding dry a very small minority of AIDS sufferers.
Now think about a vaccine. If a viable vaccine is released, *EVERYONE* gets immunized. Get the picture? Not just rich HIV+ westerners Even those who are poor, even those who *DON'T HAVE THE DISEASE* will likely get immunized via global public campaigns of the type that eradicated smallpox. After having identified AIDS as a major factor in geo-political instability, you can bet that the UN (among others) is going to make a very good effort to pump money into any viable efforts to halt/reverse the spread of this disease.
No money to be made? only a fool would walk away from this.
I hear the cynics say this type of thing an awful lot and it just makes no sense. Has there been any actual real life case of pharmaceutical intentionally siting on a cure due to profit motives? Seriously, I genuinely want to learn about historic examples that justify this kind of fear.

There was a lot of resistance when a simple cure was found for stomach ulcers. Barry Marshall [wikipedia.org] eventually won a Nobel Prize for proving that Helicobacter pylori bacteria was the cause of most stomach ulcers but it took him years to do it.
There's some good background on it in this interview [achievement.org]. It gives a pretty good insight into what happens when you challenge the conventional wisdom. The medical community were extremely sceptical and resistant to his ideas. There was no great conspiracy to discredit him, i

At this point, I don't think anything will work short of somehow granting a patient's immune system innate resistance to HIV through some kind of gene therapy approach (there actually are people working on this sort of approach, but gene therapy as a whole has a long way to go).

As for an "ulterior motive", there may be some tax advantages to it, and at the very least, it's not much of a cost. R&D and advertising are a good part of the cost of a pill; there's no profit in selling to those who can't afford it. Many drugs have a very low cost per-pill to produce, and by not passing on the advertising/R&D costs, the free medication won't make much of a difference

An HIV vaccine would, depending on price and risks, most likely be distributed to those who do not yet have the disease but may be at high risk.
