What they may not realize, though, is that they need some of the same shots in the arm themselves.
According to a report from Trust for America's Health, a nonprofit organization that focuses on nationwide disease-prevention awareness and education, up to 50,000 U.S. adults die each year from vaccine-preventable diseases. One of the main reasons for this may be that many adults think they're too old for vaccines or mistakenly assume their childhood vaccines last a lifetime, the report states. That's not necessarily the case, doctors say.
"Vaccines wear off over time and lose their effectiveness," said Matthew R. DeBoer, a family medicine physician with Baptist Primary Care, St. Johns Forest. "The body's level of immunity against diseases such as tetanus, diphtheria and pertussis decreases over time and boosters are given to keep their levels high enough to fight disease."
William Schaffner, an infectious diseases physician and co-author of the report, said it's not totally your fault if you haven't been inoculated since you were in the sixth grade. "The country has an absolutely stunningly first-rate system for immunizing children, but too many adults still fall through the cracks," Schaffner wrote in an online article posted on the American Academy of Family Physicians website. "It's really time to build a better strategic approach for systematically immunizing adults."

Good information for the general public, IMO.
