whats terrifying about this particular strain is not its virulence, but rather, the mutations that it represents in the flu virus....
essentially, our modern day flu-shots predict what antigenic shift will come from the seasonal flu... ie, a H1N4 virus turning to a H1N5 virus... which is a small genetic difference between the "n" proteins.... what it doesn\'t account for is the antigenic drift... ie an H1N4 mutating to a distant H1N1 strain.... the virus has just never been that strong/quickly adaptable within our time limits to develop a vaccine....
the purpose of getting inoculated against the flu is mostly damage control. its not intended to PREVENT the flu, but more to give people with weak immune systems a "boost" to help them fight the infection faster if they are exposed, and prevent complications secondary to the flu... ie, respiratory failure/pneumonia.
i administered 100+ flu shots this season, but opted not to get one myself.... simply because i am young with a strong immune system. any disease i can keep out of my body, i will. if, however, i had a kidney transplant and was on immunosuppressant therapy, i would certainly get a shot.
what is interesting and scary about this strain is the multiple sources of genetic material they are finding. there were known swine influenza genes in the samples they\'ve taken, known to be present in north america. however, they are finding evidence from a swine flu that is native to europe and asia, with absolutely no idea how it was transmitted. they are also saying that while it is an H1N1 virus (same as 1918 pandemic), those with antibodies to the traditional H1N1 infection in north america will probably not be immune to this strain since its so genetically different.
and spacey, you\'re right, it hasn\'t killed 7 people in Mexico, it\'s killed an estimated 7% of people its infected (pandemic of 1918= killed 2.5% of people infected)
very interested to see this unfold.... going to be an interesting next 48 hours i think !
