lumps caused by bcg vaccine

Hi doc

My son developed 3 lumps from the bcg vaccine, 2 under his arm and 1 on his clavicle. His paediatrician did not know what it was and than referred us to a peadiatric surgeon who said it would go away on its own. My son is now 9 months old and the lumps are still there.
Please advise if this is familiar to you and how do we get rid of it.

Thank you

These lumps are indeed due to the BCG and are enlarged lymph glands.This is a rare complication of the BCG vaccination, but it is not at all dangerous. These swollen lymph glands will become smaller and disappear by themselves but it can take a very long time before this happens.

Hi. I had a bcg vaccine when 16 (now 21) and developed a raised red lump at the injection site which has remained although has shrunk a little bit. I wonder if it was an allergic reaction? Is there mercury in the jab? I recently had a severe reaction to tuna steak after eating fish all my life and am at a loss as to what it could be. Heavy metal poisoning? Please advise me doc.
