Hello, could anybody give me some advice as im in a dilemma! My 15 month old son was d/x with IS at seven months, after responding to Prednislone he had a relapse but after another course he's been seizure free from June. He is due the MMR, the consultant says go ahead, but im not sure, he's so well at the moment. Has anybody been in this situation, gone ahead with the jab and everything ok? Would appreciate any thoughts, thANX
