What should I do if BCG vaccination is unsuccessful?

If BCG vaccination is suspected, you can go to the BCG vaccination institution for re-examination and tuberculin test 3 months after BCG vaccination. If the test is positive, it means that the vaccination has been successful and the immunity has been developed in the body. If the test is negative, it means that BCG vaccination has not been successful and can be re-vaccinated.

It is impossible to achieve 100% success rate of BCG vaccination for the prevention of pulmonary tuberculosis, but whether there is a scar or not cannot be used as the basis for successful vaccination, which is related to individual differences. You can go to the hospital for a check-up to see if your body has antibodies.

Immunity can be maintained for several years after BCG vaccination, and immunity can weaken over time (when the tuberculin test turns negative).

Replanting is done every 6 to 7 years, and is generally not required in adulthood.
