Is a booster dose required if a child/student received five or more doses of DTaP/DTP/DT before the age of 4?
Yes. Students must have a dose of DTaP/DTP/DT on or after the 4 th birthday. However, ACIP recommends that children receive no more than 6 doses of diphtheria and tetanus toxoids before the seventh birthday ( MMWR 1991;40 [RR-10]:6) because of concern about adverse reactions, primarily local reactions. Therefore, if the booster dose required would result in a seventh dose of vaccine, then the dose would become medically contraindicated.
