Dear,

Thanks for the query.

I presume that she received the regular childhood shots that a six month old gets in your country. Perhaps she received the penta-vaccine and hepatitis B or even the pneumococcal conjugate vaccine.

None of these vaccines are known to produce the effect that you have mentioned in your question.

I have seen the picture. It is a simple reddish patch, not raised above the skin and not associated with inflammation or any other adverse phenomenon.

May I humbly suggest that you keep a watch on the rash for a few days? You could try application of a non-allergic baby cream or just Vaseline to see if it disappears. If it doesn't resolve in a few days, please visit her doctor to personally show it to him/her and take further guidance.

Hope this answers your query. Please accept the answer if you do not have any additional queries.

Regards
-Dr. Taher Kagalwala
