Question: is adacel tdap or dtap?
Answer: The similarity of the generic names or abbreviations, DTaP and Tdap, has contributed to the confusion. The product proprietary, or trade, names are not as similar; Infanrix (GlaxoSmithKline), Daptacel (Sanofi-Aventis) and Tripedia (Sanofi-Pasteur) are DTaP products; and Boostrix or Adacel are Tdap products.
