Medical Definition of Immunization, DTaP
Immunization, DTaP: Like DPT, DTaP protects from diphtheria, pertussis (whooping cough) and tetanus. DTaP is the same as DTP, except that it contains only acellular pertussis vaccine which is thought to cause fewer of the minor reactions associated with immunization and is also probably less likely to cause the more severe reactions occasionally seen following pertussis vaccination. DTaP is currently recommended only for the shots given at 18 months and 4-6 years of age.
