Question
The baby was vaccinated with the BCG vaccine at 22 days old, but no usual scab reaction was observed; the skin did not appear red and swollen, and it seemed as if the vaccine had not been administered. Is this situation normal?
Answer
The BCG vaccine is an important vaccine for preventing tuberculosis. If a baby has not been vaccinated with the BCG vaccine, their body will lack antibodies to fight against the tuberculosis bacteria, and their risk of infection will significantly increase upon contact with a tuberculosis patient. Additionally, if unfortunately infected with tuberculosis, the treatment process will be longer and more expensive. Therefore, having antibodies is crucial for the baby’s health. If the preventive vaccination is not completed, schools may require that all necessary vaccinations be supplemented upon the baby’s enrollment to ensure the health and safety of schoolchildren.
