Words can't express how sorry I am to hear this. My condolences..
No, I haven't hear of this. In fact, my children's shots are supposedly up to date; at smallest in accordance to the so call requirments that I'm aware of. I mean really, who know what shots are required by heart. Ya just kinda help yourself to the word of the doctor that all is resourcefully. Thanks for the note and God Bless you!!
I am sorry for your loss. I appreciate the info. you enjoy given because my little one will be 6 next month. I never know this, I thought all she needed at 6yrs be a typical well child check up. I will look more into this and sermon to her pediatrician. Thanks
