Swine flu (H1N1) has been in the news since it first appeared this spring, and while there have been deaths and hospitalizations in countries worldwide, most cases have been relatively mild. And now, there is an H1N1 swine flu vaccine, too. That's the good news. But the bad news is, swine flu can still be serious, and it's still widespread. With that in mind, here are 10 swine flu "don'ts" -- things not to do for swine flu prevention.

1. Don't expect seasonal flu vaccination to prevent swine flu. The seasonal flu vaccine doesn't protect against swine flu. The H1N1 swine flu vaccine is a separate vaccination. Your best bet is to get both vaccines. Seasonal flu can be serious, especially for infants, elders, and people with weak immune systems. The CDC notes that seasonal flu or its complications kill an average of 36,000 people per year in the U.S. and hospitalize more than 200,000 people. Getting vaccinated each year against seasonal flu is the single best way to protect against seasonal flu, according to the CDC.
