Question
What to Do If There’s a Yellow Head at the Injection Site of a 40-Day-Old Baby
Answer
Hello, if the yellow head is on the left arm, it is likely the site where the baby received the BCG vaccine at birth, which is used to prevent tuberculosis. It is normal for the injection site to become purulent and discharge fluid within about a month or even longer after vaccination. However, if it is on the right arm, it may be due to regional infection, and it is recommended that you take the baby to the hospital for disinfection. Please keep the injection site clean and avoid friction. Wishing the baby good health.
