Chicken Vaccines Combine To Produce Deadly Virus

stoilis sends this quote from an article at Science: "Vaccines aren't supposed to cause disease. But that appears to be what's happening on Australian farms. Scientists have found that two virus strains used to vaccinate chickens there may have recombined to form a virus that is sickening and killing the animals 'This shows that recombination of such strains can happen and people need to think about it,' says Glenn Browning, a veterinary microbiologist at the University of Melbourne, Parkville, in Australia and one of the co-authors on the paper."

      Myxomatosis was deliberately introduced in the 50s...I think the post was referring to the rabbit calicivirus which escaped from Wardang Island quarantine station in 1996. That's actually working quite well so far, in drier areas populations are down by as much as 90% (haven't splattered a bunny on the highway in years), however it remains to be seen whether they'll develop immunity.

    The problem is, they are not wrong.

    Nope. They're wrong. So are you. The vaccines protect against specific strains of virus. If another viral agent comes along and incorporates either, or both, strains into its genetic makeup and produces a viable virus, it is now transmissible whether the host is immunized or not. Immunization may have provided the raw materials, but the product, once manufactured, no longer requires them.

    So if you forego immunization, you're vulnerable to all the strains the immunizations would have protected you against, as well as the new strain. So the anti-vaxxer is not only reducing herd immunity to the strains we can protect against, but also still just as vulnerable to the new virus. The only people who should be opting out of vaccines are those whose vaccination is counter-indicated due to a bona fide medical condition. If you aren't one of those people, and you refuse vaccination, your ass should be deported or jailed, as you pose a clear and present threat to public health -- you're in the same category to me as drunk drivers.

    Except that antibiotics do not kill virii - part of the problem with overuse of antibiotics is the general belief that they help with viral infections. Let me repeat...... antibiotics DO NOT kill virii.

    As in most complex issues the truth is somewhere in the middle. The "anti vaccine" fanatics who are rabidly against all vaccines are probably wrong. So are people like you who are pro vaccine to the point of being blind to the risks.

    Injecting vaccines, usually involving complex genetic material, preservatives, etc. in to people who are also composed of complex genetic material, is a not a no risk endeavor. Most of the time the benefits out weigh the risk, BUT. . . the more careless and cavalier the vaccines makers and advocates are the higher the risks become. Especially beware of vaccine makers who have a financial interest in everyone being injected with their vaccine.

    When the pro vaccine crowd become completely blind to the risks and start pushing every vaccine under the sun to everyone for everything its just begging for trouble. Vaccines should be used appropriately to deal with real risks. If the risks of the vaccine outweigh or approach the risk of the pathogen, or the risks of exposure to the pathogen are very low, you pro vaccine bigots can do as much harm or even more than the anti vaccine fanatics. Performing science experiments on millions of people isn't a particularly great idea unless you need to deal with a real risk, and have a well understood solution.

    The problem with your position is the fact that vaccines don't work unless a large percentage of the population is vaccinated.

    Look what has happened in Nigeria with the effort to eliminate polio.

    Cumulative decisions to not vaccinate have significant consequences to the rest of the population.

    It is very unlike abortion.

    Cross-species viruses are actually quite common, and it has nothing to do with the genetic sequences either; DNA is DNA and the code is evolved to build viruses. Usually the factor that prevents a virus from being cross species is that the surface protiens of the virus doesn't fit the receptors sites, but that can also occure in the same species. I'd be surprized if chickens are exported from Australia to the US, the cost of keeping them frozen durring shipment from Australia would be considerable and chicken just isn't that expensive.

    I for one am looking forward to my future of a different needle for a different disease every day. That's the point of "eradicating" ad disease.

    Why should I care if someone else gets infected? Well when I have a heart attack, if there's a hospital bed shortage due to some idiot that is burdening the health system all because they refused to get a vaccine shot when they were kids then I most damn well will care.

    This isn't some theoretical crap either. This has actually happened to me. I was rushed to hospital with some heart problem when I was young. I sat in the waiting room and the nurses strapped the ECG on to me where I sat because there was no enough room in the hospital due to a myriad of other factors.

    I'm not saying that people who didn't get vaccinated are at fault, just that they are a burden, a burden on my tax dollars used to provide basic healthcare in this country.

    Yet another person who doesn't understand how vaccines work.
    If everyone takes a vaccine, it doesn't need to make them all completely immune to the disease.
    All it needs to do is increase resistance enough that each person, on average, infects less than one other person. At/after this point the number of people with the disease will decrease until noone has to worry about it anymore.

    Yeah I don't buy that argument. If I am immunized from polio, what do I care if the unvaccinated idiot gets it? The disease doesn't affect me.

    I'm a parent. My kids happen to be old enough to have gotten some vaccinations (and are up to date on them), however at one point they weren't old enough to get them yet. Why do I care if someone doesn't get vaccinated? Because if enough people don't get vaccinated, herd immunity breaks down and babies (who aren't old enough to get the vaccinations), the elderly and those who can't get vaccinated for valid medical reasons (e.g. allergies) will get sick. If it was just a matter of only the unvaccinated getting sick, I'd agree with you and would argue for vaccines to be voluntary. However, since people's choices not to vaccinate can lead to the death of other people, I think it is well within the rights of the government to require them for all people (except for those with valid medical reasons).
