[SaneVax: BREAKING NEWS out of Australia may have severe implications for human vaccination programs. The viral components of two vaccines used to protect poultry from respiratory disease have recombined to create a far more deadly disease than the original. Until now, no one considered the possibility of this happening to be a viable threat. Apparently they were wrong.
Could live and/or attentuated viral cultures used in human vaccines also recombine to create a more deadly disease than the vaccines were intended to protect against? Could DNA fragments in vaccines do the same thing by combining with viral antibodies from prior innoculations? Perhaps they already have done so – no one knows. It appears the ‘science’ behind medications has moved far beyond the ‘science’ of safety.]
Chicken vaccines combine to create deadly virus
By Michael Vincent, ABC Science
Australian scientists have found that two different vaccines used to control an infectious disease in chickens can recombine to create new lethal virus strains.
The research, to be published today in the journal Science, has prompted authorities to review vaccine use in animals.
But the scientists, from the University of Melbourne, say the findings are not only important for vaccines in chickens, but also for any vaccine which might be able to multiply – including those used in humans.
Chicken respiratory virus ILT can lead to birds dying in a pool of bloody mucus, but vaccines that were meant to protect them have instead led to their deaths.
Dr Joanne Devlin, a lecturer in Veterinary Public Health-Epidemiology at the Asia-Pacific Centre for Animal Health, says the deaths were caused when two vaccines used to treat the virus combined.
“These new strains were formed by recombination from the different vaccine strains and that they were actually more virulent than the vaccine strains that gave rise to them,” she says.
“This is something we’ve never before seen before in the field.”
Live vaccines, where a weaker version of the virus is introduced to allow the immune system to build up its own defences, are quite commonly used for animals and humans, and include polio, measles, mumps, rubella, chicken pox and rabies.
The Australian Pesticides and Veterinary Medicines Authority is now consulting with industry to control the use of these vaccines.

What I am shocked with is that this disease is even happening in AU. I honestly thought it was a more natural/organic country and we plan on moving there in the near future. There is a way to raise poultry or any livestock without any chemicals, whether it’s medicine or pesticide. So many livestock here in the US is mass produced and diseased and it’s our #1 reason why we are so sick, fat and unhealthy here. I would love to plead with whomever decides to use chemicals on their ranches and farms in AU, to please keep it the way it was meant to be; natural, the way God gave it to us. Continuing to use the chemicals in you food will make you just like the US in the not-so-far future. One more sad and scary thing, is that when you decide to take these pharma companies and pesticide companies in to your homes, they will never leave.

The light a the end of the tunnel is a fire…. We are heading into extinction. We can all see it and hope science will save us. Science is helping to get us there faster.
