Baby's arm swelled up after getting the hepatitis B vaccine, and it's been almost a month. What should I do?

Patient's question:

No

Doctor's answer:

Swelling at the vaccination site after receiving the hepatitis B vaccine or other vaccinations is a normal reaction.
Advice: Your child's condition is a normal reaction to vaccination due to their personal constitution. You can apply fresh potato slices to the swollen area to help reduce the swelling.
