I've never heard of DPT, before.
DTaP contains acellular pertussis...http://www.vaccineshoppe.com/US_PDF/...4757_12.03.pdf

The acellular pertussis vaccine components are produced from Bordetella pertussis cultures grown in Stainer-Scholte medium1
modified by the addition of casamino acids and dimethyl-beta-cyclodextrin. The fimbriae types 2 and 3 are extracted from the bacterial
cells and the pertussis toxin, FHA and PRN are prepared from the supernatant. These proteins are purified by sequential filtration, saltprecipitation,
ultrafiltration and chromatography. Pertussis toxin is inactivated with glutaraldehyde and FHA is treated with
formaldehyde. The individual antigens are adsorbed separately onto aluminum phosphate.

DTP was responsible for a lot more vax reactions than aP. Though my DD reacted similarly to both
