Ebola Vaccine 100% Successful In Guinea Trial 118

An anonymous reader writes: Doctors and researchers have been testing a vaccine to protect against Ebola in the west African nation of Guinea. Trials involving 4,000 people have now shown a 100% success rate in preventing infection. "When Ebola flared up in a village, researchers vaccinated all the contacts of the sick person who were willing — the family, friends and neighbors — and their immediate contacts. Children, adolescents and pregnant women were excluded because of an absence of safety data for them. In practice about 50% of people in these clusters were vaccinated. To test how well the vaccine protected people, the cluster outbreaks were randomly assigned either to receive the vaccine immediately or three weeks after Ebola was confirmed. Among the 2,014 people vaccinated immediately, there were no cases of Ebola from 10 days after vaccination — allowing time for immunity to develop — according to the results published online in the Lancet medical journal (PDF). In the clusters with delayed vaccination, there were 16 cases out of 2,380."

    Almost a year exactly.

    • Hey, the malaria vaccine that was proven safe and effective in the 90's just finally got out of UK regulatory hell last week. About a million kids a year die from malaria. In the time they were bickering about the typeface on the label about 330,000 kids died from malaria. But we need that kind of officiousness and palaces and such for "civility". Those kids weren't white anyway.

      Now it goes WHO regulatory hell, but if we're "lucky" the bureaucrats there will only let a quarter million kids die while the

        Things have improved greatly but not enough. The WHO decision to allow DDT use again was probably the most important factor while waiting for the vaccine. (There are some fairly unknown skeletons in the DDT closet, they are probably not what most think.) My most recent trip, Nigeria, was actually a lot tamer than it once was. Things are looking up there and this is a good thing. I am of African decent, partially at least, and I do donate what seems reasonable but a lot of that goes to waste as it ends up be

    • Of course, no one in their right mind would even consider the possibility that black people invest in research to stop a disease that is rampant in their own countries... Black people shouldn't have any kind of responsibility for their own lives. They _need_ white people to provide them with food, medicine, etc. And to think otherwise is racist.

      While food and medicine is ok, please keep in mind that white people shouldn't attempt to provide free transportation and jobs. That's also racist.

    Having a 100% proof vaccine for Ebola is nice, as long as it works for the majority of strains and also lasts for life. Not so good if it lasts for 1 year and you need another, and only for one specific variety of Ebola, not all.

      I'm really concerned that it might give children autism! I mean, imagine surviving an almost guaranteed fatal case of hemorrhagic fever, and the becoming autistic?

      I think we have to ask ourselves "Would Jenny McCarthy give her ebola-stricken child this vaccine?"

      • You're going for funny, but too many people would say that 100% seriously. As the parent of a child with autism, I resent the implication those people make that a child is better off dead from measles than "damaged" with autism. Sadly, too many people have skewed risk-benefit calculations because they hear horror stories about vaccines and haven't seen first-hand the horrors of the diseases vaccines prevent. I guarantee that an Ebola vaccine would be greeted by long lines to get the vaccine and not quest

      Even an Ebola vaccine that was only effective for a short period of time would be wonderful. Ebola isn't a subtle disease, and outbreaks tend to start in fairly isolated villages, perhaps because the reservoir is an animal. When someone in a village starts bleeding out of every orifice, administer the vaccine to everyone in the village. That stops the outbreak in it's tracks.

        And, as another poster pointed out, aide workers/doctors/nurses could be vaccinated when they go into an infection zone to treat patients without risking infection themselves. Even if the immunity only lasted a few months, I think any doctor would take the occasional jab over risking Ebola because they were so hot and tired when taking the suit off that they made a small mistake and got exposed to the disease.

          Even if the medical staff and volunteers are vaccinated and immune, they may still carry the disease back with them.
    • Having a 100% proof vaccine for Ebola is nice, as long as it works for the majority of strains and also lasts for life.

      Not necessarily. I'd say it remains 'nice' even if it only lasts for 6 months, so long as it works on 'most' strains, but said strains are identifiable.

      The critical part here is that it works when given close to exposure. That makes it like the rabies vaccine. Ebola outbreak? You hit everybody in the village up with it, and it remains at 1-2 cases, not hundreds.

      If it's 100% effective for life with 1 shot, it goes way beyond 'nice'. As such it would beat most vaccines today, as most vaccines are: Only a

    • It's still good in that case, it gives nurses and doctors a chance to survive.
  • I'd be impressed if it had 100% success in the real world.
    • by Anonymous Coward

      Are you trolling? Did you even read the summary? The "trial" WAS the real world.

      As an aside, the ethical implications of that are a little bit unfortunate. IE: Their "control" was to delay intervention for the control group by 3 weeks. As a consequence: 16 people were infected who could have received the vaccine...

    • Given the size of the trial, it's really unlikely that it prevents less than 90% of the cases of Ebola that would otherwise develop. So while I agree that 100% continuing is all that likely, especially if you start including immune suppressed people such as the HIV positive, those with cancer, transplants, young children, the elderly, etc... Still, if you vaccinate 100% of those eligible for it and it provides 95% immunity to Ebola, odds are the vulnerable won't be exposed at all, because you'll have some

  • news like this makes me so mad. because it demonstrates something wonderful we as a civilization have achieved time and again. something that should be applauded and celebrated and championed:

    1. disease, unfair deaths

    2. science, hard work by intelligent people

    3. vaccine, innocent lives saved

    it's obvious, straightforward, undeniable, a wonderful good

    against that we have prideful ignorance, that continues to claim the lives of innocent children and others, simply because of their various paranoid conspiracy theories, lies, and petulant low iq

    in a just world, those who don't vaccinate die from ebola

    in the real world, those who do vaccinate protect those who do not, and when the herd immunity breaks down, because of the unvaccinated, the vulnerable innocent and the unlucky few who got a vaccine but it didn't take hold, also die

  • Believe what you want. This is just bad statistics. Are there any real epidemiologists or statisticians in the study that claim it's 100% effective?
    If there were only 16 cases in the delayed vaccination groups, you simply do not have enough information to calculate the real efficacy.

    • by bws111 ( 1216812 )

      It doesn't say it is 100% effective, it says it had a 100% success rate IN THE TRIAL. Which it did. The TFA says that the actual effectiveness will be between 75 and 100%. But it is sooo much easier to just criticize than simply read, isn't it.

  • Now if we can only get Malaria, Dengue and Chikungunya to US soil we're sure to cure those devastating third world epidemics as well!

  • This a human vaccine, which is great, but it will probably won't avoid the next break out.
    Wouldn't it be a good idea to also develop a vaccine for bats, which act as a reservoir for the virus?

It is easier to write an incorrect program than understand a correct one.
