The U.S. Centers for Disease Control and Prevention has counted 37,000 H1N1 cases so far in the United States, with 211 deaths.
Canada has reported more than 10,000 swine flu incidents, with 49 associated deaths.
By contrast, Britain suffered 21,000 deaths attributed to seasonal flu in the 1999-2000 winter alone.
Now, out of almost 30 million people, 49 deaths is not huge. I don't plan to get the shot, but will sure wash my hands a lot! Mom and I are taking small containers of sanitizer on our cruise...wouldn't be surprised if the ship had containers on board.

Judging from the above, it makes more sense to get the seasonal flu shot.
