The article is entirely free of side-effect data. Reducing my H1N1 infection probability from 25% to 2.5% might be worth a poke in the arm, but more severe side effects have been reported. If I had to guess, I'd say the benefits outweigh the costs, but without data for both, that's nothing more than a guess.

There is also research that suggests that getting a regular flu shot may increase the chance of getting H1N1, so it's possible that the interaction between the various flus and vaccines is more complicated than we thought.
