How effective is Tdap when given to an adult who has not received a primary series of DTP or DTaP?
There are no clinical data on this situation because this population was not included in the Tdap clinical trials. Tdap is FDA approved as a one-time booster dose. However, ACIP feels that one dose is better than no doses and, thus, made the off-label recommendation. Future data will provide evidence on the effectiveness of this dose.
