HIV Vaccine Trial Shows 90% Immune Response 386

fergus07 writes "Researchers at the Spanish Superior Scientific Research Council (CSIC) have successfully completed Phase I human clinical trials of a HIV vaccine in which 90% of volunteers developed an immunological response against the virus. The MVA-B vaccine draws on the natural capabilities of the human immune system and 'has proven to be as powerful as any other vaccine currently being studied, or even more,' says Mariano Esteban, head researcher from CSIC's National Biotech Centre."

    I'd be learly of this until Phase II and Phase III are completed. Developing an Immune response is different then having a successful vaccine. The antibodies have to be ones that will help in eradicating the infection, and since HIV mutates so rapidly there is no grantee that it will work long term in world wide eradication.

    Historically take a sample set of people considered to be at-risk for HIV, give them safer-sex counseling, and then track them against a control for infection rates. This study was different (hate to say RTFA, but it does describe it):

    Development of MVA-B is based on the insertion of four HIV genes in a previously used vaccine (MVA) for smallpox. When injected with the vaccine, a healthy immune system can react against the MVA, whilst the HIV genes are incapable of self-replicating. This guarantees a safe clinical trial for HIV free volunteers. Furthermore by trialing the vaccine on healthy patients, the immune system can learn how to detect and combat the HIV virus components. "It is like showing a picture of the HIV so that it is able to recognize it if it sees it again in the future", says Esteban.

    In the US there has been one known HIV transmission through blood transfusion in the last 8 years the chances of getting HIV from a blood transfusion are 1 in 1,500,000. 1 in 400 people who get stuck with a needle or cut with a sharp from a person with HIV contract the virus there have been 57 cases of health care workers getting HIV at work there are 12,000,000 health care workers. Getting HIV is not that easy mostly bad decisions have to be made to get HIV. The chances that you get HIV from a source besides sex and sharing needles is too small to consider 0.000002% you have a better chance of dieing from constipation.

    What the hell does any of this have to do with the US? The vaccine from the original article wasn't even developed in the US. HIV isn't an epidemic "in the US", but that doesn't mean it's not worth pursuing a vaccine.

    If you want to quote statistics - in Africa the estimate is 250-500 people a DAY contract HIV from unsafe (either contaminated blood or equipment) transfusions. Some 3rd world countries in Asia are almost as bad. And since there is such a higher rate of HIV and such poor health care conditions, it's much more dangerous for the health care workers as well.

    But I guess same pseudo-moralistic bullshit attitude that would pretend to argue HIV is not a world epidemic and is only contracted by all of those fornicators and addicts probably doesn't give a shit about anyone outside of their tiny little world, anyway.
