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.
One of the most widely used vaccines around the world are DTaP and TDaP. âDTaPâ stands for âdiptheria,tetanus, and pertussisâ or whooping cough. âTDaP,â on the other hand, also stands for the same types of diseases being prevented. However, the latter is a booster vaccine. DTaP is given to children who are at the age of seven and below to prevent the major diseases that are listed. TDaP, on the other hand, is a booster vaccine.
