Take the Tetanus Quiz

The correct answer is
Tetanus is now rare in this country because children are immunized against it, in a combination vaccination that also protects against diphtheria and pertussis (DTaP). Most cases are found in people over 60 who have not had a booster vaccination, so their immunity has gradually waned. That trend may be changing, however, because tetanus is increasing among IV drug users. Two tetanus vaccines available for adults: Tdap and Td. Tdap vaccine is used to prevent tetanus, diphtheria, and pertussis (whooping cough), and Td vaccine prevents tetanus and diphtheria.

Adults should get a diphtheria-tetanus (Td) booster once every 10 years throughout their life. For one of their booster doses, adults ages 19 to 64 should get the Tdap vaccine instead of Td. You cannot get tetanus from the vaccine.

Although tetanus bacteria can enter the skin through something as small as a pinprick, they prefer deep wounds. Clean any wound you get with soap and water, followed by an antiseptic. If the wound is deep or dirty, have your doctor check it out. If you haven't had a tetanus booster in more than five years, you may need to get another booster. Be sure to provide your immunization record to your health care provider.
