For a 4-year-old, use DTaP (diphtheria, tetanus, acellular pertussis), not Td/Tdap.
If no previous documented DTaP doses
Give:
- DTaP today
- DTaP after 4 weeks
- DTaP 4 weeks later
- DTaP 6 months after dose 3
Because dose 4 is given at age 4 years or older and at least 6 months after dose 3, a 5th DTaP dose is not needed.
If partially vaccinated
Use the documented doses to continue, not restart:
- Minimum interval dose 1 to 2: 4 weeks
- Dose 2 to 3: 4 weeks
- Dose 3 to 4: 6 months
- A fifth dose is only needed if dose 4 was given before age 4, or less than 6 months after dose 3.
The U.S. CDC defines full vaccination as 5 valid DTaP doses, or 4 valid doses when the fourth was given at age 4 years or older. See the
CDC catch-up guidance and
DTaP recommendations.
If this is because of a wound: clean the wound and seek same-day medical assessment. For a dirty or major wound in a child with unknown or fewer than 3 tetanus-containing doses, clinicians may give tetanus immune globulin (TIG) as well as DTaP. The exact plan depends on the wound and the vaccination record.
Schedules differ by country, so share the country and prior DTaP/DPT dates if you want the exact catch-up dates.Do you mean vaccination advice for family members after a child’s tetanus catch-up vaccination, or vaccination of close contacts for another infection?
