…H5N1 …bird flu, is mutating faster in countries that have …wide-scale, but incomplete, vaccinations of poultry, according to a report published online in Vaccine (October 12). The genetic changes …rendered the vaccinations ineffective, and increased the risk that the virus could jump to humans.
…viruses circulating in countries with mass vaccination efforts were evolving faster, and had become genetically distinct from the virus that the vaccine was designed to combat.
"...H5N1 has already been the cause of a chicken apocalypse. Once it learns to go human to human there'll be no stopping the damn thing."
'We ignore bird flu at our peril'

I'm so jealous of these Asian countries that have most of their populations in masks at the malls and grocery stores, I can't wait for our air to get just as deadly here in America.
Yay vaccines! Always good stories connected to vaccines.
Contagion: Could it really happen? - BBC NEWS
Hollywood blockbusters are not normally known for their scientific accuracy. So how realistic is the new disaster movie Contagion, which depicts the spread of a killer virus across the world?
'Too late to contain swine flu', 'Sars virus 'mutating rapidly', 'Bird flu fear as mutant strain hits China and Vietnam'.
These are not lines from the film. They are all real headlines from the past decade.
They all relate to illnesses which it was feared could spread around the globe and kill millions.
But, while each has claimed lives, none has become the feared "modern plague".
So how realistic is the depiction of the spread of the fatal infectious disease in Contagion?
According to one scientist who has already seen the film, the answer is very.

2 points.
1) I also want a mask and think we should get in on that fad.
2) Sadly a face mask isn't going to do anything for us in the face of the types and levels of contamination we are facing globally.

So vaccination programs are making bird flu mutate faster - and more likely to jump to humans. Not a surprise.

A more complete vaccination program would reduce the pool in which the virus can survive, and reduce the number of variations that appear.

WTH?
Step up everything we know to pump the immune system?
But wait... didnt the last pandemic attack the stronger immune systems harder? ( Pigflu)
Don't give up on advanced human bird flu cases -expert
An expert who treated numerous bird flu victims in Vietnam has urged doctors not to lose hope with patients who are admitted late to hospital as there is still a good chance that they can survive. ..."If you can decrease the viral load (with drugs), you can have a good outcome. Even those who are treated late had good results," he told the conference.
...de Jong, head of virology at the Hospital for Tropical Diseases in Ho Chi Minh City in Vietnam, said Tamiflu could still be used to fight bird flu many days after the onset of symptoms because the avian virus would still be multiplying. ...De Jong agreed with many experts that an early start to treatment was still best ..."You have to get very effective treatment as early as possible because you will prevent direct viral damage (to lung and other tissues)," de Jong said.
…Early treatment could also prevent what is known as the "cytokine storm response", when a human's immune system launches such a heavy counter-attack that it destroys not only the invading avian flu virus, but the person's own surrounding tissues as well...
Do we all rush to get vaccinated? Or will these vaccines be the recombination which will aid in the transfer of the mutations?
Are the vaccines that are administered to 1 day old chicks at poultry houses actually causing the chickens to get sick later or be weakened to other strains they would otherwise have a natural immunity to?
WTH?
there have not been the large numbers of kids sick at school this year from flu.
I would have loved to see the movie contagion but my town refused to run the movie for fear it would disturb the students at the local Baptist College.
If we meddle with the natural process of life, we must expect some consequences.
The viruses that make us: a role for endogenous retrovirus in the evolution of placental species
….There is now sufficient evidence to suggest that horizontally transmitted agents and gene sets allow the rapid adaption of various living systems...
….We currently think of a virus as an agent that necessarily reduce host fitness and generally cause disease, together with other pathogenic microorganisms, such as bacteria and fungi. …viruses can also invent systems of molecular genetic identity and superimpose a new combined identity onto the infected host. In so doing, a virus can allow the host itself to adapt to the environment and evolve quickly, providing a creative force that the host may further develop into systems of identity and immunity that can contribute directly to host evolution.
...the genomes of placental mammals are also highly infected with retroviruses found only in their genomes (endogenous) and because retroviruses are generally immunosuppressive, I examine the possibility that the embryo is acting like an infectious agent that produces virus to suppress the mother's immune system.
…parasitic viral-like genomes may represent one of the primary mechanisms for the evolution of higher order living systems.
