Hello. I spent the evening filling out forms for Early Childhood Education Classes, and while filling out my son's immunization information, I noticed that he had recieved 5 of the PCV vaccine, instead of the required 2-4. It happened when the switch was made from PCV-7 to PCV-13. He had received 3 doses of 7, and 2 of the 13. I feel TERRIBLE that I lost track of something so important, but it's done and I can't change it. The 5th dose was given about 2 months ago, he obviously didn't show any side effects, but I am VERY upset.. Do I need to be concerned about future problems? What do I do? I know it's late to have noticed.. I am absolutely ashamed..but concerned beyond belief..
