Question
What should I do if my baby’s arm swells after vaccination?
Answer
Hello, if your baby experiences arm swelling after receiving a vaccination, it is typically due to the BCG injection. In this case, a rash may form on the arm, which usually heals on its own over time. You don’t need to worry too much, but if the symptoms persist or worsen, it’s important to take your baby to a health department or hospital for a professional doctor’s examination and treatment.
