A tetanus shot is generally recommended every 10 years for most adults to maintain protection. For babies and young children, multiple doses of the DTaP vaccine are given early on, with booster doses recommended for preteens, teens, and adults. In the case of certain wounds, particularly deep or dirty cuts, a tetanus shot may be advised as soon as possible if it has been more than 5 years since the last dose. Pregnant women are recommended to receive a Tdap vaccine during each pregnancy to protect the newborn from whooping cough as well as tetanus.

Key points:

• Routine booster every 10 years for adults.
• Children receive several doses of DTaP in early years.
• Adolescents get a Tdap booster at 11-12 years.
• A tetanus shot is recommended sooner (within 5 years) for some wounds.
• Pregnant women get Tdap during early third trimester of every pregnancy.
