Q.	I don't remember when I had my last tetanus shot—how often do I need one?
A.	People tend to keep better records of their children's and pets' inoculations than they do of their own. Recommendations for immunizations are fairly clear-cut, although there are exceptions. You should get a tetanus/diphtheria booster every 10 years. If you can't remember when you had your last shot, ask your doctor whether you should get a shot. Generally, doctors recommend that you get the tetanus/diptheria booster. While visiting the beach last summer, my friend fell and lacerated her elbow. Because she carried her health information in her wallet, she was reassured that her last tetanus shot was 3 years ago—and she didn't have to ruin a day at the beach by leaving to get another one. 20108875(6)-03/08-EBS-CON
