Its nothing to worry about.I am not a doctor but I have kids who have experienced the same.I later learnt that if the BCG does not behave that way,it is considered ineffective and has to be repeated later on.Thats why most if not all people who have had that vaccine have a scar.Your doctor should know this and should explain it to you clearly.Otherwise just take care of the wound as adviced.

@shak..I think its the body's way of reacting to that vaccine..anyway it should clear in a few days time..but also don't press or try to expel the abcess as in a normal boil....this one will heal by itself .

"BCG is given as a single intradermal injection at the insertion of the deltoid. If BCG is accidentally given subcutaneously, then a local abscess may form (a BCG-oma) that can sometimes ulcerate, and may require treatment with antibiotics. However, it is important to note an abscess is not always associated with incorrect administration, and it is one of the more common complications that can occur with the vaccination. Numerous medical studies on treatment of these abscesses with antibiotics have been done with varying results, but the consensus is that once pus is aspirated and analysed, providing there are no unusual bacilli present, the abscess will generally heal on its own in a matter of weeks."

Nurses possess different skills at administering vaccines especially the injectable ones. If you can, have the senior nurses or the matron in MCH give the vaccine. If you let the KMTC student nurses do it...

@sanity, it drains as i clean it with hardly any pressure and is not showing any signs of reducing

@sanity, i'll try not to panic. Thanks for the reassurance

Dr. Fred Were: great doctor. Thanks to the wazua community for the reference. Reassured me that the abscess was a good reaction to the vaccine and that there was no need to worry. The swelling is going down and is now healing. And my daughter loved him!
