The pertussis vaccine we currently administer is a combination vaccine that primarily includes diphtheria, pertussis (whooping cough), and tetanus, commonly referred to as the DTP vaccine. It is generally administered for the first time when a baby is three months old, the second dose at four months of age, and the third dose at five months. A booster vaccine is given again when the child is one and a half to two years old to produce antibodies that can effectively prevent pertussis, a respiratory infectious disease. It is important to detect early, vaccinate in a timely manner, and prevent early.
