The United States is getting ready to release the 160 million doses of Swine Flu Vaccine this coming October though a number of manufacturers is having troubles about it, US has declared they really will.
Though, medically, swine flu is not really that alarming compared to dengue fever (according to its physiology), this might sound good especially to those infected areas like the Philippines. In fact, the A(H1N1) flu virus has been regarded as pandemic case already. It has spread over continents.
There are actually a lot of studies going on regarding the swine flu vaccine generation. The US is much hoping that the soonest they could release such vaccine.
