My concern is that if they're not getting the samples they need from Asia, then an effective vaccine is not being developed at this time.

The virus has mutated and human to human spread is now occurring. I'd like to see the mortality rate on cases that are pinned to that origin.

I haven't seen any information which indicates that a vaccine that is even partially effective is being produced today. We've pretty much run out of time.

Here's where things stand now (from Recombinomics):

http://www.recombinomics.com/News/05110503/H5N1_Recombination_Serious.html

"As noted above, the 2005 genes have changed. Genes do not change via reassortment, which merely shuffles existing genes. The Z genotype is defined by reassortment, and the vast majority of the current H5N1 isolates are the Z genotype, including isolates from Japan, Korea, Indonesia and many provinces in China. These H5N1 isolates have not been reported to cause fatal human infections. However, the Z genotypes in Vietnam and Thailand have caused infections with a high case fatality rate. It is the region-specific differences in the genes that are associated with the reported fatal infections in humans."

In other words, nobody has any answers. Without specific information, no vaccine can even begin to be manufactured. With AT LEAST 6 months required for vaccine development, and more for mass manufacture, I don't look for much help from science, frankly.
