Side effects of the BCG Vaccine
Normally, once the BCG is given (upper right arm), a small pimple appears in 1-3 weeks and lasts up to 6-8 weeks. A small scar will remain when the vaccination heals.
However, some possible side effects that may occur include:
- A drainage or a small scab over the site. If the injection site is draining, put a dry gauze dressing on the area and allow it to dry and prevent the baby from scratching the area. There is no need to put a band-aid, cream or ointment on the site. It will normally resolve itself, usually within one to three months.
- On rare occasions, an abscess (painful swelling that contains pus), forms at the injection site and/or lymph glands in the armpit or neck can get larger. If this happens let your nurse know.
