my 2 month 6days old baby got pus over government 1vaccine (tika)

A. It’s a side-effect of the BCG vaccination if you remember previously people used to get a mark on the body now they get some or the other problem like this but it is a very common things to you don’t have to worry about it it is building Puss inside it which means it’s an infection so if you have knowledge how to punch in it and clean it and after that you can apply beta then then you do it yourself otherwise consult a doctor it’s not a problem it’s a very common issue
