It's flu vaccine season, and this year the new quadrivalent vaccines are looking more promising than ever. Time to get your shot (or your snorty nose thing). Here's where to find out more.
The CDC has an excellent, frequently-updated page on the vaccines available.
The Health Map guys have this awesome shot locator, where you can find the exact shot you want.
Plus, you can follow the "pathogen bot" on Twitter. It tweets out news items about influenza about once every hour.
