My daughter had swine flu a couple of weeks ago, as I posted in a thread before Mori took it off topic. She had fever for 1.5 days and vomited intermittently for a few hours. Wife (a pediatrician) gave her a revved up course of tamiflu and normal course of tamiflu to the rest of the family. She was fine and only missed one day of school. No one else in the family caught it either.
My advice would be, if you are wanting to avoid the vaccine, make sure you get tamiflu called in at the first sign of a fever. There's been very little resistance by the virus to tamiflu and none to Relenza. There have been some reports that tamiflu was "ineffective" but I know the one other time my daughter had flu, she did not recover in just a couple of day's time. Perhaps the virus was milder than the last seasonal flu she got.
As for vaccines, we all already have had the flu-mist, active virus version of the seasonal vaccine and have gone that route the past couple of years. The year before that, the vaccine was ineffective against the prevailing strain and we all ended up with flu anyway.
My wife is of the opinion that the rest of us did not contract the virus from my daughter since none of us even showed the slightest signs of sickness. So we will all still get the H1N1 shots when they are available.
But really, neither she nor any of her partners seem to be incredibly concerned about this flu. It doesn't appear to be anymore potent than any of the seasonal flus. People do die from those, as numerous folks have mentioned, regularly.
Of course, don't take anything I say as medical advice. Just giving my opinion(learned that one from my wife).
