Patient's question:
The child had received the third dose of the hepatitis B vaccine and developed a slight fever the next day, with temperatures fluctuating between 37°C, sometimes burning and sometimes not. The body was also feeling hot. Desired assistance: Hello, what could be the reason? Should I take them to see a doctor...Doctor's answer:
After vaccination, the recurrence of low fever, redness and swelling at the injection site, and the formation of lumps are normal, and they usually appear again about 24 hours after vaccination.In addition, some children may experience symptoms such as "headache, dizziness, general weakness, chills, nausea, dry vomiting, abdominal pain, and vomiting." These symptoms generally subside within 24 hours and rarely persist for more than 3 days. If there is a high fever, fever-reducing medication can be taken. Once the body temperature returns to normal, other symptoms usually subside on their own. If the low fever does not subside or if other abnormalities occur, it is important to seek medical attention promptly.
