How to look after the BCG vaccination site
What to expect after your child receives the BCG vaccine
In 1–6 weeks, a small, red blister may appear where the injection was given. This should heal in a few weeks.
After 6–12 weeks, the blister may turn into a small, weeping sore. If this happens, cover the site with gauze to allow air to get in. Do not use sticking plasters.
The sore may take up to 3 months to heal, and may leave a small scar. This is normal.
