Revere recently had an excellent post about why you should get a flu shot. Let me just add one more reason: the best way to avoid contracting influenza is to be around people who don't have it. While this sounds like something Yogi Berra might say, containing influenza is a group effort. This is a very serious public health problem: the 'ordinary' flu 'only' kills 37,000 people per year. That's right: for every person in the U.S. who dies from AIDS, there are two who die from influenza.
And getting enough people vaccinated, particularly those aged 5-18, could cut the number of deaths by 80%.
If you live in Massachusetts and can't find time to see your doctor, or if you don't have health insurance, here's a list of public flu clinics for MA.
