BCG make it subclinical infection which means there are mycobacterium in the bloodstream but they don’t cause clinical picture of TB. Thank you for your question.
Doctor I want to know why insipite of bcg vaccine during childhood ,a person may get infected to tuberculosis??
Thank you so much. I appreciate spending sometime visiting our website. We will be glad to see you coming back.
Its a nice!.
A know a few doctors in USA who send the patient for a Xray. If the xray is negative then they only repeat it every year. How about that?
Personally, I agree with you but unfortunately neither USA Doctors nor USMLE agree with you. I know BCG vaccine is mandatory in some countries like Egypt and it can lead to a positive reaction but also remember that there is still a quiet few cases of active TB even of those who took vaccine. The reason I put this question is that: In order to pass the USMLE, you have to answer it the way they believe is the correct answer in USA even if it is different from what you were taught in schools. Thank you for this great question.
why i give him a prophylactic therapy while he give positive because he was immunized obligatory in egypt previously while he wwas a child
