There's been articles in the press here in the UK over the last few days that re. the normal seasonal flu shot 'experts' are 'cautiously optimistic' that the normal seasonal flu shot offers some form of cross protection with the new H1N1 flu, i.e. one might still get the 'new' flu but it will be less severe and complications should not arise.
I've been having the seasonal flu shot for nearly 20 years (I have various auto immune conditions) and I do think there is some truth in this, last month I came (unknowingly) into very close contact with someone who had the H1N1, also since then people at my work have come down with it, yet I have not caught it - maybe I'm fortunate but with my with auto immune conditions believe me, I normally get everything!
I get the seasonal flu shot every year (my dr. calls me in, along with other high risk patients), I had it 4 weeks ago, I've also been called in for the new H1N1 shot but I've declined that, however, according to my friend who is a receptionist at my dr's, since the news article about the seasonal flu shot, they've been inundated with people ringing up after it.
