In my opinion, the Swine Flu is just another version of the flu. I do not think it is any more dangerous than the other strains out there. (editted to add:for Boyd's sake, I hope not.) It seems to be able to effect people in warmer weather more than some other strains. I think it has been blown way out of proportion by the media who sell advertising and certain other people who advance their political agenda by scaring people, regardless of the facts.
Our government is doing what it can to provide a vaccine effective against a strain they expect to be prevalent this year. Every year they have to guess pretty early which strains are going to be most active and develop a vaccine to combat those strains. The swine flu came on the scene a little too late to be in the original vaccine design but i think they are doing a good job in catching up.
With that said, I had pneumonia several years ago and my doctor recommends I get the flu shot every year as I am more at risk than some people because of previously having pneumonia. I get a flu shot every year. I don't see doing anything any different this year.
