Is hereditary allergy to BCG possible? What can affect its absorption in general? My husband had late BCG due to blood transfusion during birth after subsequent allergy and a lymph node was removed. Previously, there was no allergy in anyone in the family. At present, my husband's daughter born in July 2020 is now one week old and the place where the BCG was done stopped bleeding (the baby was born at 8 months). Could this be what? Please tell me, I am very afraid for my daughter. ?I recently learned about pyoderma and it has become scary. My husband said that he just didn't inject correctly and I believed him. Now it's scary.
