Patient's question:
My child is currently attending kindergarten. A few days ago, they received the DTP vaccine at the kindergarten. Upon returning home, we noticed redness and swelling at the injection site, along with a hard lump. That night, the child had a low-grade fever and also lost their appetite. They mentioned feeling chest tightness and shortness of breath. Our family members said this is a normal reaction after vaccination.What kind of help do I need: How long does the adverse reaction to the DTP vaccine take to recover?
Doctor's answer:
After receiving the DTP vaccine, some children may experience pain, redness, and mild fever at the injection site. Generally, no special treatment is required. If the child's temperature is below 38°C, keep the injection site clean and dry. You can use a clean towel to apply warm compresses and ensure the child gets adequate rest and drinks plenty of fluids. If the temperature rises above 38.5°C or other abnormal reactions occur, seek medical attention promptly. Typically, some low-grade fever and loss of appetite may occur within two days after vaccination, which is a normal reaction. Some redness and swelling may also appear at the injection site, and most adverse reactions usually subside within two days. If high fever or convulsions occur, it is essential to go to the hospital for immediate examination and treatment.
