What Does Bump At Injection Site Indicate?
Hi,My baby had a BCG injection at 2 months of age. For about two months after the injection, there was nothing visible at the injection site. Then, a little bump formed, which subsequently got red. Over about 6 weeks since the bump appeared, it got bigger, redder and got crusty. Now it looks like there is a yellow spot in it, as if pus is under the skin. Is this an expected reaction? Why did it occur so late? All my friend s babies had a reaction in 4 to 6 weeks after the injection and heals in a relatively short time, not months. Should I be worried?

Hi...this is an expected but rare reaction to the BCG vaccination. Sometimes there will be pus collection, but no need to panic. If it is causing fever, then you need to see a pediatric surgeon as get the pus evacuated.
