First things first: yes, there are some people who shouldn't get the flu shot. If you think you might be one of them, check with your doctor. For everyone else, getting the yearly flu vaccine is still the best way to keep yourself healthy, productive, and on your co-workers' good side during the upcoming flu season. People in your office will thank you if you don't bring the sickness in to work, and your body will thank you if you can avoid feeling like death by getting a simple shot in the arm. Seriously, what are you waiting for?
