+1 per Doug & others as to getting the shingles vaccine in you late 50s - early 60s. Same with pneumonia as per Les' post. After you get one pneumonia shot, get the Previnar shot, as soon as a Doc allows. It broadens the range of pneumonia prevention. Don't forget to get a DPT booster, albeit they call it something else now. Same re flu vaccine , but I recently read that seniors may want to wait until Oct.-Nov. to get the flu shot to insure best immunity during the worst of the flu season. Check with a doctor on this issue. If you travel or like raw seafood, get the Type A & B hepatitis vaccine, as well.

I learned the Hep vaccine lesson the hard way, from a bad raw clam. Almost did me in as result of getting a secondary bacterial infection from being compromised by the Type A Hep infection. Can you say 106.5 fever spikes for ~10 days, a 25lb. weight loss I didn't need and a reduced work schedule for about 6 weeks, because I was "shot" by 2:30pm.

Lastly, if you have kids, who might become sexually active ( yes, entertain the possibility from about age 10), make sure they get the HPV vaccine. Prevention is not an invitation to promiscuity no matter what some zealot may tell you. Same re safe sex education.

Edit/Addition: I think that if I lived in a flood prone area, especially if it's a warm climate, I'd talk to my Doc about getting the Typhus & Typhoid vaccinations.
