HIV Vaccine Trial Shows 90% Immune Response
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."
Healthy relationships would kill HIV 100%, not 90.

The macrophages engulf it just fine now. Of course, they break it up, and then parts ultimately get picked up. So, what is needed is to BLOCK its site without causing any side issues.
this?
idiot.
That's great. This combined with existing anti-retroviral therapies might actually extinguish HIV from the face of the earth in only a few decades, if used widely.
You have never had sex, have you?
As long as PhiCorp doesn't stock up on the vaccine in anticipation of Miracle Day I think this looks like some promising news.
sooo.... what happened to the other 10 percent? They all got HIV? That would suck.
What do you think?
I can finally go back to sharing needles. I gotta save money, what with the economy in the gutter.
Rofl, they still have aids.
Nice anti-government remark ;)
"The MVA-B vaccine draws on the natural capabilities of the human immune system"
Isn't that how *all* vaccines work?

I was wondering how do they perform clinical trails? Do they inject the vaccine with a person and then have him have sex with a HIV positive lady?
I'd like to take a moment to thank the brave people who are undergoing this study for the sake of humanity. I'm sure they're being compensated accordingly, but I nevertheless think it takes a huge amount of humanity to say, "Sure, I'll try out this vaccine and then you can try and infect me with something I will suffer under for the rest of my life, for the good of the world." Perhaps I could be wrong, and there will be no deliberate attempt at infection, (which would make for a very weak trial, I think). But even still, thanks to all the voluntary guinea pigs in the world who are taking risks to help save the rest of us.
Oh yeah, they never did cure Herpes, did they? :(
You are woefully uneducated. I suggest you use your google-fu on other ways HIV is transmitted.
Yes, sex with an infected partner. And sharing of needles, blood transfusions, and babies born from infected mothers, to name a few.
You stereotypers are all the same...
I wonder if a vaccine against AIDS will result in a sexual revolution as happened in the '60s with the advent of birth control pills.
And yes, I do know there's more then one STD out there, but that didn't stop them in the 60's either.
Looks like the big, homophobic Guy in the Sky takes another one in the 'nads from our friends in the medical research community.
I wonder what Pat Robinson's got to say about this. He's been remarkably quiet since all those tornadoes ripped through the Bible Belt, sucking up true believers like a vaccuum cleaner on meth.
I've calculated my velocity with such exquisite precision that I have no idea where I am.
So does this mean we will have a cure for this?

I guess they finally managed to cram the required shit-ton of money into a single syringe.
On 1983, the year the HIV was "discovered". I'm glad I might actually live to see it extinct.
There's always OUTLIERS, on any sampling curve statistically, or via linear optimizations, as in multivariate calculus or statistics solutions, lol...
Ah, anyhow/anyways: Between this article now today, & this a day or two back here -> http://science.slashdot.org/story/11/09/25/123230/aids-vaccine-breakthrough ?
Well - to think, that I might have seen AIDS knocked off in my lifetime, perhaps??
* I think it's awesome! AIDS seriously screwed up my "social life" & everyone's imo, because most folks I knew began to well... 'slow down' in their "meanderings", so to say, because of it. Is it a bad thing or good thing? Both probably, but it's just an observation from experience here.
APK
P.S.=> BOTTOM-LINE: My Hat's off to the medical world lately, this is something that's truly good news & so was the link I posted...
I hope either method works out to knock out this ironic bastard AIDS (the thing that creates life kills slowly & miserably, being that irony)...

HIV vaccine in which 90% of volunteers developed an immunological response against the virus.
This is an absolutely meaningless measure; seroconversion against HIV is easy to achieve, and typically worthless. The elicited antibodies end up being targeted to highly variable regions, and have little long-term neutralizing power.
Although a handful of unusual broadly neutralizing antibodies have been found among "elite controllers", it is extremely rare for typical individuals to generate them. There's been some speculation it might be possible to create an effective vaccine by directing the response away from decoy regions, and towards the handful of areas targeted by such elite antibodies. Thus far, nobody has managed such a feat, unfortunately.
This was a Phase I trial; why are efficacy claims being given? Phase I trials are done to test for safety in humans, not to test for efficacy. From the NIH:
---
Phase I: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase II: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase III: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
---
Someone call me when there are results from Phase III trails. Until then, this is really not news. (Only about 1 in 10 compounds makes it from Phase I to market...)

Just because an immune response in the form of circulating antibodies from B cells is seen does not mean infection and replication will not occur when a person is exposed to HIV; most people with HIV have high levels of HIV antibodies circulating in their blood, but the rate at which the virus mutates, as well as the fact that the epitopes the body naturally develops immune responses to are "hidden" by the way in which the viral capsular proteins are folded means that the antibodies do little if anything to halt infection. Furthermore, the CD4+ T cells which initiate a more effective immune response are one of the two types of cells the virus infects (the others being macrophages). At this point, the article gives no further details or useful specifics. If they had said they had generated a cytotoxic CD8+ cell response, or perhaps an immune response against one of the conserved regions of the gp120 or gp41 viral receptors, then I'd be interested. Till then, I am going to be quite skeptical about this until they have some efficacy data. (I am a medical student with an MS in biomedical science)
you give them the vaccine, wait a while, draw blood, expose that blood to the disease, then watch under a scope and see what happens.
I've decided to Diversify my Holdings. I've divided my cash between my left and right pockets, instead of all in one.
Vaccines against viruses work because they train the immune system to attack the virus. They introduce something that gets it going. Can be a dead virus, can be a live but weakened virus, but whatever the case it trips off the immune system which produces a tailor made response. The immune system can then use that to kill any future invasions from that virus.
This is the same thing that happens when someone gets sick. However in that case, the live (in so far as a virus is alive) and fully active so it overwhelms the body for awhile until the body can formulate the response and fight back. All the vaccine does is make that process easier and safer.
The flip side of that is if it is the sort of thing the immune system fights off, but then it comes back, well a vaccine won't work, at least not a vaccine in the classical sense. If the immune system can't develop an effective repeating method to kill the virus, then a vaccine won't help.
Really this shit is not a big medical conspiracy, it is just how things work. What's more, the more things we cure, the harder the things are that remain. We fixed the things that were easy to fix long ago. We are getting to the hard shit now.
I was on a blog once where a guy posted that there's only about a 1/1000 chance of contracting it from an affected person. He then got flamed into dust. I looked up his numbers and it's actually true! During normal sexual intercourse, the rates are 1/1000 male (infected) to female and 1/2000 female (infected) to male. With rates that low, I don't even think "sexually transmitted" is the right word. You probably have to have an open wound, scratch, or open sore from another STD to transmit the virus.
Now, when you start getting kinkier (e.g. anal) the rates start going up. I can't recall the numbers for these, but I think they were around the percentile range (give or take a few factors of 2). I think because the skin in your nether regions is much thinner and porous. This is why the gay community has been so devastated by AIDS. Additionally, the rate of HIV in gay males is 1/5 with half that number not even being aware that they're infected :(
I swear to God...I swear to God! That is NOT how you treat your human!
it delivers the goods... bitch.
For those playing the home game:
Science: million+
Alternative meds: 0
The Kruger Dunning explains most post on
Actually it would be (unfortunately) God 1,800,000, Science 0. 1.8 million have died from AIDS, and (as far as we know) science has yet to provably cure anyone of HIV or AIDS.
As far as Pat Robinson goes, I'm sure he's just waiting for you to be flattened by the homosexual steamroller that Jerry Falwell was nice enough to warn us about.
I do have to say, though, as someone with family in the 'Bible Belt', I wouldn't mind running a steamroller over you a few times for your casual disregard for their risk of death due to natural disaster, simply because of their proximity to people you hate. It'd be fun to watch. In the meantime, though, feel free to catch AIDS and die before this gets FDA approval.
wait... The ethics... I thought it took years of study before human trials can be done.
..So are the other 10% kinda fucked?
If HIV vaccines are put into use, all those quick ELISA HIV antibody tests will be rendered useless. In the US, we already have that problem with TB tests, since the rest of the world vaccinates for it. Those who have been vaccinated usually are forced to get an X-ray to prove they are TB negative. Alternative HIV tests are much more expensive. Design a new test now... profit in 10 years.
this?
Homosexual idiot.
FTFY.
How could a phase 1 trial (http://en.wikipedia.org/wiki/Clinical_trial#Phase_I) show 90% effectiveness? Phase 1 trials are about the safety of the drug, not its effectiveness.
All that phase 1 trials attempt to show is that the drug is not deadly to healthy people and what dosages might be useful. The long-term effectiveness is still to be proven.
I'm inclined to see the point of implementing eugenics in a way that doesn't just amount to racist BS.
I listen to both RIAA and non-RIAA stuff if I like the music, tangential business/politics nonwithstanding.
“Up to 90% of the total decline in the death rate of children between 1860-1965 because of whooping cough, scarlet fever, diphtheria, and measles occurred before the introduction of immunisations and antibiotics.”
Dr. Archie Kalokerinos, M.D. PhD
Historical trends indicate vaccines have had little positive effect: Historical trends show that deaths caused by childhood illnesses had already declined as much as 98% before vaccine programs were ever initiated. Evidence indicates that an improved standard of living, better nutrition, and increased sanitation, caused this drop in disease, not vaccines
In 1954 the Americans pushed forward a polio campaign. What happened within the first year was that to their horror they found that particularily one type of the polio vaccine was causing polio. Because the vaccine is not a killed virus, your giving polio in a partly killed form. They got rid of that particular type of the vaccine. Then they realized that all the forms of the polio vaccine caused polio. So what they did is redefine it. They only called it polio if you still had paralysis after 60 days. Now in most cases polio paralysis resolves after a few days. So that's how the statistics of polio went down. By changing the definitions. Dr. David Ritchie

whoosh? :)
Substitute 'Medicine' for 'Science' and you're in the main right, and why should it be any other way?
Even if a vaccine ever ends up being approved for HIV, there's no doubt that there is going to be a whole wave of controversy around actually vaccinating people, as is the case with the HPV vaccine. Since so many parents think that vaccinating their kids for HPV is just giving them another "green light" to have sex when they're younger, I am sure the HIV vaccine would be met with that same response, if not an even greater one. It will be a huge hindrance to a great achievement.
Good euphemism.
My hat is off to those who volunteered to be injected with HIV for science. Even if it was a non-replicating version of the thing...
seriously?!?!?! so let me get this right... since this is a vaccine, you need the treatment before being infected. Therefore this study has gotten volunteers to take the vaccine and then be exposed to the virus? These volunteers must be desperate!!! I'd hate to be the 10% with the death sentence.
What? An underfunded public organisation has made this breakthrough before big pharmas?
These spanish boffins are very smart or big pharmas don't have much interest in a HIV vaccine...
