Hello, thank you for sending your question to Vinmec Health System, to your question, I would like to answer as follows: If your child is fully vaccinated against TB With the right course of treatment, your child is likely to have full immunity to TB. However, in some cases, such as: the quality of the vaccine given to your child is not guaranteed (possibly due to improper storage during transportation to the user), or not on the scheduled time. your child may not have full immunity. In this case, the risk of TB infection is still there. Therefore, the best way is for the child to take safety measures when in contact and definitively treat his father's TB. As for oral drugs to prevent TB, there is currently no vaccine, only vaccination. May your family stay healthy!
