Our DS13 has been treated for PANS/ chronic fatigue/Lyme's for three years. Our insurance company requires us to vaccinate for pneumonia in order to meet the criteria they set OR they wont cover IVIG therapy for our CVID son. Our Immunologist who works with lots of PANS kids highly recommends it bc she says its harmless and could help protect him as well as help his case if we need to move to IVIG (so it will be covered). There is no way around it for CIGNA and yet so many parents have had bad experience with vac's. We haven't vaccinated him since a baby and limited then so really afraid ! but he has NO protection from pneumonia according to his labs. Dr J insists it will help in many areas and she has not seen any issues. UUUHHHGGG!!! Stable now for 1.5 years.
