Patient's question:
When my baby was born, they received the BCG vaccine. At birth, the hospital administered the BCG vaccine, and then they told me to go to the health station at three months to check if it was successful. Now that my baby is four months old, there's a large lump and a pustule at the injection site. I don't know if it was successful, and I'm also unclear about what the BCG vaccine prevents.What kind of help do I need: What does the BCG vaccine prevent?
Doctor's answer:
BCG vaccine is a vaccine used to prevent tuberculosis. It is effective in preventing severe forms of tuberculosis in children, such as tuberculous meningitis and hematogenous disseminated tuberculosis, with a prevention rate of 30%-80%. In daily life, it is important to avoid contact with people suffering from pulmonary tuberculosis, as active pulmonary tuberculosis patients are the source of tuberculosis transmission.
