How long to wait between Td and Tdap?

The Centers for Disease Control and Prevention (CDC) recommends that there should be at least 10 years between Td (tetanus and diphtheria) and Tdap (tetanus, diphtheria, and pertussis) vaccinations for adults. However, if a person has a wound that requires a Td booster and it has been more than 5 years since their last Td or Tdap dose, they should receive Tdap instead. It’s always best to consult with a healthcare provider for personalized recommendations.
