HIV Vaccine Ready For Clinical Trials

Posted by Zonk on Sat Jul 21, 2007 11:38 PM
from the go-science-go-science dept.
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."

    ...not HIV but full blown aids?
        • 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.

            AIDS is simply HIV infection to the point where HIV has suppressed the immune system enough to cause an AIDS-defining illness (essentially an illness, usually infection, which would not normally happen in an immunocompetent individual), or the CD4 count (a kind of immune cell) is low enough to infer immunocompromise. Hardly definition by association.

          AIDS and HIV were once considered separate. The definition of AIDS was modified to require HIV.

          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).

            Retrovirus contain RNA which through reverse transcription modifies the hosts DNA. Large portions of DNA are useless garbage only there as place holders.
            I'm not sure that our relatively rudimentary understanding of genetics is capable of supporting this assertion. While introns are certainly excised during transcription, to suggest that they, and other non-coding sequences, are "useless garbage" is probably not a scientific viewpoint. While it may seem that non-coding portions of DNA simply serve as placeholders at our currently level of understanding, it is perhaps possible that these repeating sequences are part of a secondary code that serves a useful (but as yet unclear) function. IANAGeneticist, but I believe that the jury is still out on the concept of "junk DNA".

            Of course, it's entirely possible that the code is indeed useless, but that would seem to go against the tendency of evolution to be frugal.

              evolution occurs by selective breeding, not by viruses modifying our DNA. do you think monkeys caught the virus to become human one day and started walking upright?
              No. Evolution is the combination of two processes:
              • Mutation.
              • Survival of the fittest.
              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.

                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.

        Abstinence is not 100% effective.

        Coupled with:
        - not being born to an HIV positive mother
        - not sharing needles when injecting drugs
        - not receiving tainted blood product transfusions
        - not being bitten, scratched or otherwise suffering an infectious injury from a carrier
        - not sustaining a needlestick injury if you are a healthcare worker from an HIV carrier
        - not partaking in lower (but still not zero-) risk sexual activities (e.g. oral sex)
        - not being exposed via other means (e.g. blood injuries in sports)

        there are probably a few others I haven't thought of, but stop being so sanctimonious. There are a lot of people out there who contracted HIV through no fault of their own - one of the largest groups were haemophiliacs before the disease was even known about.

    As someone who has actually worked on an HIV vaccine (a plasmid-based DNA vaccine), I have to caution that the field is a graveyard of failed attempts, ranging from traditional vaccine methods a century old, to exotic cutting-edge variants. There is considerable skepticism that an HIV vaccine (even given a very elastic definition of "vaccine") is even possible, in part based on the apparently complete absence of any "natural" sterilizing immunity. At best, there exists a small population of non-progressors who are able to hold the virus at stalemate due to genetic variations in certain receptors, a mechanism that seems unhelpful as far as vaccines goes (although relevant to drugs, specifically entry-inhibitors).

    While VLPs (virus-like particles) are certainly a promising vaccine technology (the cervical cancer vaccine that's been in the news recently is VLP-based), I really am pessimistic that it is the solution to the substantial problems that any working HIV vaccine would have to overcome. 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).

      If the current infection isn't destroyed, what is the use of future immunity? And does 'immunity' even have meaning in that case?
      Actually, *most* vaccines on the market are designed to produce a response against future exposure rather than treating a current infection - that's exactly what immunity means in medical terms. It would be worthless to immunize against most diseases after they've been contracted anyway, since the body has already been presented with immunogens and should be developing a response; HIV/AIDS is a special case because of A) its success at avoiding effective immune response and B) its ability to destroy the immune response.

      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. Since some of the highest risk patients (people who engage in unprotected sex and IV drug users) are less likely to go tell their doc they need it, let's hope it gets cheap and safe enough to make it a mandatory childhood shot!

            If you're one of those people who 'sleep around', do so cleanly, do so safely, keep track of who you sleep with, get tested regularly; and if you do get tested positive for any STD, tell those who you slept with since the previous test (+ some time, due to incubation times) to get tested as well, as it is likely that 1. you got it from one of them* and 2. you gave it to some of them.

            If you can't bring yourself to act responsibly, then I'm sorry - I can't bring up much sympathy for you when you do get an STD.

Once while drawing blood from a lady, the lady went psycho and blood ended up spraying into my mother's eye. Why were they drawing blood? She had common symptoms of AIDs. Those next few days were hell for the entire family (First, the lady refused to give blood again for testing, and second the labs still process it at the normal rate, despite the fact it happened on the job), thankfully it turned out said crazy lazy did NOT have AIDs or HIV. Could you fairly have cursed a faithful wife and mother to AIDs through such a silly claim? Furthermore, what's wrong with sleeping around, anyway? I shouldn't just have to defend it with my own mother...

        Being gay might not increase your chances of getting HIV (-> AIDS), but having gay sex might. The reasons are:
          - more tissue trauma in receptive anal sex
          - more promiscuity in gay community in general

        HIV has recently become more transmissible during vaginal intercourse too (possibly through its fairly rapid evolution) though so it may catch up, but until the straight community becomes as promiscuous as the gay one, the transmission rate will remain lower.

        The first cases of AIDS were associated with gay men

        That is false. I think that you mean that the first cases detected were with gay's. The first cases were shown to come from Africa and traveled around via hetro sexuals. It was seen first in the gays, because of the liberal attitudes in bath houses of the 70's and our attitudes of gays back then (most were married).
