Patient's question:
My son received the BCG vaccine 22 days ago. I heard that there should be a scab at the injection site, but my son has none. There's no redness, swelling, or any visible signs of the injection. Is this normal?Doctor's answer:
Hello, the role of the BCG vaccine is to prevent tuberculosis. If you haven't been vaccinated with the BCG vaccine, the body will not have antibodies. After coming into contact with a tuberculosis patient, the chance of being infected is relatively high. If you do contract tuberculosis, the treatment time will be longer, and the cost will be higher, making it quite troublesome. Therefore, it is definitely better to have antibodies. Moreover, if your vaccination is not completed, you will need to complete these vaccines before you can attend kindergarten and elementary school.
