Vaccine for newborn baby, the BCG vaccine was administered on the 33rd day of birth, and now it's been 54 days. Why hasn't there been any inflammation or scar as mentioned in the materials? There's no trace on the back of the hand at all.Previous treatment history and effectiveness: Hello, is this a normal phenomenon? Thank you for your concern.
What kind of assistance is needed: Could there be any issues?
Doctor's answer:
This vaccine should be administered subcutaneously or intramuscularly. When administering the BCG vaccine, it is absolutely forbidden to use the same syringe, to prevent an increase in hepatitis infection rates. Ampoules with cracks or expired should be absolutely discarded. The reaction after vaccination is different from general preventive injections. Typically, about 3 weeks after vaccination, redness and swelling may reappear at the vaccination site, which gradually softens in the center, forming small white pustules. When the pustules rupture, pus is discharged, and it takes 1-2 weeks for crusting to form. After crusting, a round scar may remain.
