Although the child would be considered complete for tetanus and diphtheria toxoids, she is not complete for pertussis vaccine. DTaP vaccines are FDA-approved only through age 6 years so no more DTaP doses are recommended.
However, ACIP recommends that children age 7–10 years who are not fully vaccinated against pertussis (defined as 5 doses of DTaP or 4 doses of DTaP if the fourth dose was administered on or after the fourth birthday) and who do not have a contraindication to pertussis vaccine should receive a single dose of Tdap to provide protection against pertussis. If the child in this case is age 7–9 years at the time of Tdap vaccination, the next dose due will be the routine adolescent dose of Tdap at age 11 or 12 years. If the child is age 10, the dose counts as the adolescent dose and no additional dose at age 11 or 12 years is recommended.
