Re: BCG wound
A typical BCG vaccination causes a small red spot to develop within 2-6 weeks and a lesion forms after 6 weeks. It usually becomes scaly, crusty with slight bruising and will eventually form a scab and then heal to form a round flat scar. The vaccination site should be left uncovered to heal properly. They normally heal within a 3 month period but can take up to 5 months. The vaccination is normally given intradermally in the upper left arm at the insertion of the deltoid muscle. The scar that remains sometimes resembles the scar that a smallpox vaccination leaves.
If your BCG vaccination site is still bleeding after 4 months, you might want to consult your doctor or the clinic that gave you the vaccination. How old are you and what country do you live in? Have you received a BCG vaccination previously or is this your first?
