 Gene-swapping vaccines spawn lethal poultry virus
Three vaccines used to prevent respiratory disease in chickens have swapped genes, producing two lethal new strains that have killed tens of thousands of fowl across two states in Australia, scientists reported on Friday.

The creation of the deadly new variant was only possible because the vaccines contained live viruses, even though they were weakened forms, said Joanne Devlin, lead author of the paper published in the journal Science.

Devlin and her team discovered how closely related the two new strains were with viruses in the vaccines after analysing their genes.

"What we found was the field viruses ... were actually a mixture of the genomes from different vaccine viruses," said Devlin, a lecturer at the University of Melbourne's School of Veterinary Science. "They actually combined, mixed together."

The viruses emerged in 2008, a year after Australia started using a European vaccine along with two very similar Australian vaccines to fight acute respiratory disease in poultry. The illness causes coughing, sneezing and breathing difficulties in birds, normally killing 5 percent of them.

The two new strains, however, were far more harmful, and since they were created have killed up to 17 percent of chicken flocks across Victoria and New South Wales, the two main chicken rearing states in Australia.

"What could have happened was one chicken was vaccinated with one vaccine and later was exposed to the other vaccine somehow, from nearby chickens," Devlin said.

ppp ppp Can you imagine if this happens in humans...as they push and push people to get vaccinated...here take the H1N1 vaccine along with the H5N1 so we can create a super mutated virus that will destroy the world...
