when was dtap vaccine introduced
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.
