Kerry blames flu vaccine shortage on Bush

As public health officials scramble to find more flu vaccine and experts debate how to increase the US supply, presidential candidate John Kerry hopes voters will come to one conclusion – the severe shortage the United States now faces is President George Bush’s fault.

Over the past several days, the vaccine shortage has been injected squarely into the presidential race, as Bush defends his administration and Kerry tries to hold him responsible for the loss of nearly 50 million doses of vaccine - half this season’s expected supply.
