how often do you need tetanus shots

Tetanus shots are generally recommended every 10 years for adults to maintain protection against tetanus. For babies and children, a series of shots is given beginning at 2 months old, with booster doses through early childhood. Adolescents receive a Tdap booster at about 11 to 12 years of age. Adults who have not been vaccinated previously should complete a series including a Tdap shot followed by boosters every 10 years. For certain wounds, a booster may be recommended every 5 years. Pregnant women are advised to get a Tdap shot during the early part of the third trimester of every pregnancy to protect their newborns. Some studies suggest immunity may last longer, but the CDC and most health authorities still recommend a 10-year booster schedule for safety.
