What are some side effects of the pertussis vaccine?
Signs of a serious allergic reaction, which may include difficulty breathing, hives, itching, and swelling of the face or throat, usually occur a few minutes to a few hours following vaccination, as stated by the CDC. There are two types of pertussis vaccines: DTaP, which doctors administer to children under the age of 7, and Tdap, which doctors give to children and adults between the ages of 11 and 64. Both vaccines protect against pertussis, tetanus and diphtheria.
