Question
What are the benefits of getting the flu vaccine for children to avoid many other diseases caused by the flu?
Answer
If a child develops purulent formation after receiving the BCG vaccine, it may be due to a low immunity or deep injection site. In most cases, children can recover on their own, and as long as there are no other complications such as swollen lymph nodes, there should not be too much impact. It is recommended to go to the vaccination unit for a check-up, and if medication is needed, some anti-tuberculosis drugs can be used. If the body temperature is too high, it is best to be hospitalized for observation and treatment.
