Question
My child has been crying and fussing constantly lately, and they’re not eating much. Do I absolutely need to get the diphtheria, pertussis, and tetanus vaccine?
Answer
Both the diphtheria, pertussis, and tetanus vaccine and the diphtheria and pertussis vaccine are necessary to receive. However, the diphtheria, pertussis, and tetanus vaccine is administered at 3, 4, 5 months, and between 1.5 to 2 years old. The diphtheria and pertussis vaccine is given at 7 years old. Since you are now 7 years old, you can receive the diphtheria and pertussis vaccine.
