Question: is dtpa a live vaccine?
Answer: DTaP. DTaP (also DTPa and TDaP) is a combined vaccine against diphtheria, tetanus, and pertussis, in which the pertussis component is acellular. This is in contrast to whole-cell, inactivated DTP (DTwP). The acellular vaccine uses selected antigens of the pertussis pathogen to induce immunity.
