Patient's question:
The baby is six months old and received the third dose of the hepatitis B vaccine and the first dose of the meningococcal vaccine. There is some swelling and warmth around the injection site on the arm. Is this normal?Doctor's answer:
This is a normal antigenic reaction. Most children who receive two or more vaccines simultaneously may experience fever, but it's not a concern. Drink plenty of water, stay warm, and if the temperature exceeds 38°C, you can take some fever-reducing medication to alleviate it. Generally, they will recover within a week.
