The Centers for Disease Control and Prevention (CDC) recommends that children receive the tetanus toxoid as part of the DTaP (diphtheria, tetanus, and acellular pertussis) vaccine series. Adults should receive a booster dose of Td (tetanus and diphtheria) every 10 years. In certain situations, such as after a severe or contaminated wound, a booster dose may be required if the last dose was administered more than five years ago.
