positive PPD

my 5 month old had a swolen red reaction 48 hours after a PPD test, the nurses told me it was positive but I wasn' t happy with the explanation of what that means. one said it could just be because he was exposed to someone with TB or he could be having TB. it was/is all confusing. my baby had a TB vaccine when he was a day old, how does that help as far as contracting the virus is concerned. they gave him Isoniazid tablets to be taken 1/3, five times a week.his dad went to another doctor and she prescribed Rimcure paed to be taken 1 seven times week. I would like to know which one is best to take and if the someone could explain the positive results to me once more? thank you

Your baby had the BCG vaccination at birth which offers some protection against the severe forms of TB. The BCG vaccination can cause the PPD test to be slighly positive, but in your baby's case the test is strongly positive. This suggests that he has been exposed to someone with active TB. He does need to be treated on Isoniazid tablets daily for 6 months.
