I have a patient who received single-antigen tetanus (TT) in the emergency room rather than Td or Tdap. Should he be revaccinated?

ACIP recommends that patients needing prophylaxis against tetanus always be given either Td or Tdap rather than TT, as long as there is no contraindication to the other vaccine components. If it’s already been given and the person had not yet received Tdap as an adolescent or adult, you should make certain that he gets Tdap as soon as feasible. If he had received Tdap previously, he can wait until the next scheduled booster dose is due to get his routine Td or Tdap booster.
