The vaccination against tuberculosis is given as an injection into the skin of the left shoulder of the newborn. Five or six weeks after the vaccination, the scar will get red and swollen, and it might also produce wound exudate which is perfectly normal. However, it is important to get the possibly swollen axillary and clavicular lymph nodes examined by a doctor. Later, the only reminder of the vaccination is a pale mark or on rare occasions, the temporary swelling of cervical and axillary lymph nodes. The vaccination scar is checked at six months, and if the mark has vanished, re-vaccination will be necessary before the baby turns one year old.
