The DTaP vaccine prevents the spread of diphtheria, tetanus and pertussis from an infected or exposed person to another person. The Federal Drug Administration introduced the DTaP vaccine in 1997 to replace the DTP vaccine formula, which was linked to safety concerns in young children. Similar to other childhood immunizations, DTaP side effects are minimal when compared to the risks of contracting one of the three diseases it protects against.
DTaP and Tdap refer to similar combination vaccines in which the component with lower case 'a' is acellular. Also available is the DT or TD vaccine, which lacks the pertussis component. The Tdap vaccine is currently recommended by the CDC and covers tetanus, diphtheria and pertussis (CDC Vaccines, 2013).aptacel is for active immunization in infants and children 6 weeks to 6 years old. Adacel is indicated for active booster immunization as a single dose in persons 11 to 64 years old and is the first vaccine approved as a pertussis booster for adults.
