A tetanus vaccine can be administered at any time after a chronic injury if the patient’s last tetanus toxoid-containing vaccine was administered more than 5 years ago. The Advisory Committee on Immunization Practices (ACIP) recommends that a tetanus toxoid-containing vaccine is indicated for wound management when more than 5 years have passed since the last dose.[1] This recommendation applies regardless of the type of wound, including chronic injuries. If the patient has not previously received Tdap or their Tdap history is unknown, Tdap is preferred for persons aged 11 years and older.[1] 1.A tetanus toxoid–containing vaccine is indicated for wound management when >5 years have passed since the last tetanus toxoid–containing vaccine dose. If a tetanus toxoid–containing vaccine is indicated for persons aged ≥11 years, Tdap is preferred for persons who have not previously received Tdap or whose Tdap history is unknown. If a tetanus toxoid–containing vaccine is indicated for a pregnant woman, Tdap should be used. For nonpregnant persons with documentation of previous Tdap vaccination, either Td or Tdap may be used if a tetanus toxoid–containing vaccine is indicated.
