Good article by Orac (of Respectful Insolence) on how the flu still kills people, and how necessary it is to get vaccinated against it.
When you read the latest screed by the latest antivaccinationist telling you that you shouldn’t get the flu vaccine, consider this. It is true that the flu vaccine could be better. It’s true that it doesn’t provide you anywhere near 100% protection against the flu (although in years when the vaccine matches the flu strains well it is quite good). It’s even true that flu vaccines (for adults, anyway) may contain mercury in the form of the thimerosal preservative that is still in some flu vaccines. You should get it anyway. The risk is minuscule, and the flu can still kill. You might think, as Bill Maher does, that just because you’re perfectly healthy you can prevent the flu with healthy living and, if you’re unlucky and get it anyway, weather its effects with little difficulty.
