My little man is 15 mths and has GERD from birth. We have decided to having the 12 mth single vaccines due to Coeliac history rather than the MMR and we have an apt with Dr Richard Halvorsen to implement a single jabs program, minus mumps of course for our son. My question is has anyone's child with GERD had either the single or MMR vaccines and if so, how have they been with regards to reflux and behaviour? We are also interested in the new Meningitis B vaccine and it's suitability for a GERD baby?
