A 25-year-old female asked:
Must a bcg injection cause pus on babies arm?

No: The goal is to get inflammation (doesn't need to be pus) at the injection site so that the baby's immune system can remember the injected material. The result is a sore (ulcer), then a small scar. If there is pus, the reaction may be too big. One's pediatrician can examine the injection site and nearby lymph node areas to see if the reaction is too big. We don't use the BCG vaccine in the US.
