HIV Vaccine Ready For Clinical Trials 385

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."

    People are just making crass jokes and whining rather than actually recognising that this is a great step in the right direction for finding a cure/prevention for AIDs. I hope that all the cynicism about drug companies ensuring it never gets out is unfounded...

    What virus? if what the article says is correct (and im understanding it properly), the vaccine is a "virus-like particle" which has the major HIV protein markers and coatings, that are common across all strains of HIV (but lacks any actual RNA to inject into cells). The marker's will hopefully trigger the immune system to build resistance. Now that thats out of the way, this sounds kinda fishy. It's one thing to come up with a vaccine, but it also claims to be a cure for HIV infections that have already taken place. As much as I wish that was true, it seems so improbable that the first 'cure' for a viral infection that we ever develope is not only vaccine, but also against what is possibly the deadliest virus lying around.

    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!

    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.

    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.

    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.

    insightful???

    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.

    Indeed. This strikes incredibly close to home, actually. My mother is currently a nurse. 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...

    There is a difference. A lot of people see sleeping around as a bad thing that a person is doing deliberately: an immoral act of will. Very few people see an accidental needle prick, or a bad blood transfusion, or being born to someone HIV positive, as a bad thing that a person is doing deliberately.

    Neither act deserves HIV, of course. Well, with the possible exception of people who are careless with other people's hearts... and almost none even among them. Unless they're also child molesting neo... oh, er... that wouldn't be good for the kids, since you don't want the molesters to have HIV. Maybe we hit them with baseball bats?

    but there's everything wrong with doing so irresponsibly. HIV isn't the only STD out there, after all.

    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.

    * assuming you didn't get the STD through blood contact/kissing**
    ** yes, the virus involved with a cold sore ( herpes labialis / HSV-1 ) will happily live in those other mucous warm areas, albeit extremely rare for it to travel southward. Similarly, genital herpes ( herpes genitalis / HSV-2 ) will happily nestle in the mouth.

    The trouble with the line of reasoning (regarding supression of an AIDS vaccine) is the assumption there is one amorphous "big pharma". "big pharma" consists of hundreds of different companies. If one of them found a cure for AIDS they would be insane not to release it. Because if the technology and science had got to that stage, sooner or later one of their competitors is going to replicate the feat one way or another. The PR cachet for being the company that cures AIDS would be utterly priceless.

    This does not require the rationale that large pharmaceutical companies have a conscience. It would still apply even if the company in question was run by a total sociopath.

    "It would still apply even if the company in question was run by a total sociopath."

    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.

    Or maybe we should accept the fact that people will eat crappy food and drink and smoke and not exercise, they will drive cars and climb mountains and walk through bad neighborhoods, and they will have sex whether anyone approves of it or not. And then deal with the results on that basis.
    The problem is not in accepting that fact, but in who exactly you want to "deal with the results" once they happen. The GP was correctly modded down for playing down the importance of finding a cure for this terrible thing, but as you noted, the majority of people afflicted with AIDS have contracted the HIV virus through needles(usually illegal drugs) and sexual intercourse. Just because god doesn't exist doesn't mean that keeping sexual contact with one healthy partner and avoiding dangerous practices is not a fantastic way to stay healthy.

    Let's find a cure and get it to as many people as possible, but let's not forget that prevention is better than any cure, and that only you are responsible for your own actions.

    A working HIV vaccine will BANK SERIOUS COIN for whoever sells it.
    Sure, but it will also replace an even MORE SERIOUS AMOUNT OF COIN that the pharmacos currently make selling treatments to victims. What is better for a pharmaco:
    1. selling an exorbitantly expensive treatment which does not cure the disease for 5-10 years
    2. selling a single shot
    It is in the pharmaco's interest to keep patients alive, as dead customers are not repeat customers. If the pharmaco sells a single shot that can cure or prevent an STD, then it can continue to sell Cialis and other "lifestyle drugs" to the couples who are now free of STDs.

    Third, what makes you think governments would subsidize it? Apart from those whose medications are already subsidized, that is.
    People would emigrate to those countries and live there for the requisite number of years to get immunized.

    There's some good arguments to support your claim - yet I doubt it.

    Pro: The classic argument for survival of the fittest religion is Circumcision for the early Hebrews. Other area religions sacrificed their first born sons to the various Bels (Baals in the OT spelling) and Tiamat types. The Jews made it a symbolic sacrifice, their populations grew faster, and they won a series of wars by it, or so the argument goes.

    Con: A sexually transmitted disease is a half-assed infectious disease that can't spread by any better means. Sex will transmit even very sensitive germs, easily destroyed by a few seconds exposure to the rest of the environment. Germs that will die from a little cool air or a few seconds exposure to solar UV will manage to pass through intercourse. The real professional infectious diseases have developed methods such as surviving long term in dirty drinking water, exploiting fast multiplying insect species as intermediate hosts, or even the aerosol spread of some plagues, that make them literally billions of times more efficient than STDs at surviving and multiplying. So if a religion tended to survive by discouraging the spread of STDs, One could have done a lot better by discouraging the spread of other diseases.
    "Cleanliness is next to Godliness" would have really caught on. The movement by the dark ages Europeans to reduce bathing (supposedly started to conserve increasingly scarce firewood) would have faltered quickly and not lasted for over 500 years. Similarly, bad beliefs, such as believing that black cats are unlucky and so hunting down animals that slowed the spread of plagues by killing rats, would have died off swiftly as people who believed otherwise tended to survive. If the selection pressure from the black plague and a dozen other major epidemics wasn't enough to make the old black cat superstition die out, then the selection pressure from STDs would just about have to be pretty minimal.
