27. Re: Flu

Influenza does a terrible job packing up it's DNA when it's done replicating. It grabs random bits from the host organism. As a result, the flu virus is constantly changing. Which is why there's a new vaccine every year.

The problem is figuring out what virus is going to actually spread this year. "Flu season" starts first in China, and usually the most prevalent viruses there become the versions that spread through the rest of the world. So the flu shot is "this year's" flu, but sometimes they're wrong about which flu are the ones that will spread.
