Patient's question:
The BCG vaccine given at birth has been purulent for half a month now, and it has now with a 2 cm diameter, constantly oozing pus. About the previous treatment and its effectiveness: The doctor said it was infected and the inflammation has subsided, so it was bandaged. What help do you want: Is there any sequelae? I want to know what's going on.Doctor's answer:
The local reactions after BCG vaccination are different from other vaccines. The majority of children will experience local reactions again 3 to 4 weeks (primary vaccination) or 1 to 2 weeks (booster) after receiving the BCG vaccine. This process involves redness, swelling, infection, pustule formation, ulceration, and scab formation, and typically, the scab falls off after about 3 months, leaving a scar at the site. This is a normal reaction process after BCG vaccination and is a sign of an effective vaccination. If this reaction does not occur, it may indicate successful vaccination, and should be considered.
