Fever after DPT vaccination can be observed, temperature measurement, proper rest, physical cooling, oral antipyretic drugs or hospitalization. Pertussis is generally a combined vaccine for pertussis, diphtheria and tetanus. When children are vaccinated, an immune response will occur and protective antibodies will appear. However, individual children may cause an overly strong immune response in the process of producing protective antibodies and develop fever. 1. Observation and temperature measurement: Individual children may develop fever after vaccination, but the temperature is usually not too high, so family members can observe and measure the temperature. 2. Appropriate rest: Rest should be appropriate to avoid exertion and prevent fever from worsening. 3. Physical cooling: family members can wipe with warm water, apply ice pads or drink warm water in small amounts and many times, which can help to lower the temperature. 4. Oral antipyretic drugs: If the child’s temperature exceeds 38.5 ℃ or more, it is necessary to give antipyretic drugs orally, such as ibuprofen or acetaminophen symptomatic treatment. 5. Hospitalization: If the child’s fever does not go down, or if the child has convulsions, vomiting, or mental abnormality, go to the hospital promptly. People who are allergic to DPT vaccine, when there are various acute or chronic infectious diseases, when there is fever, when there are central nervous system infections, epilepsy and other neurological diseases, should not be vaccinated with DPT vaccine. It is forbidden to bathe the child after receiving DPT vaccine. Pay attention to rest, drink plenty of water, do not do strenuous exercise. Pay attention to keep warm, don’t let your child catch a cold and flu, and consult a doctor in time if you feel unwell.
