Is taking BCG injection twice harmful?
Patient: Hi doctor,My baby boy is 1 month old. He as born on 27 th of January, monday. We were told that the bcg  injection as  given on the same day he was born. Later the doctor asked us to come back on next Monday to take bcg. They assured that it was not taken on that day. So we made my kid take the vaccine the next Monday. But now we can see 2 scars one has popped out and the other one is about to. Please let me know if there's any side effects of taking the vaccine twice.Shyama. Doctor: Hi, I had gone through your question and understand your concerns.No , there are no side effects , it is not a reason for concern, but there will be two scars which is normal BCG reaction . As two are closely spaced scar formation is also not a problem,  in case of interval of more than 4 weeks due to  immunity development  scar may be a bit larger but it is not going to harm baby.Hope this answers your question. If you have additional questions then please do not hesitate in writing to us.Take care.•     DISCLAIMER: - All the information provided here is for information purpose only   , it is not a substitute for the advice of a physician after physical examination , it is not intended to replace your relationship with your doctor.
