Hi--
we went through something very similar in that our daughter had some reactions to shots early on and we decided to go with a delayed vaccination schedule. Early on, our doctor had the separate antigens for the MMR, but, the last time we went, she said they are no longer available since the manufacturers didin't find them profitable. Our doctor said that she feels the makers will bring them back if enough parents complain, though. For us, I said I would continue down the delayed vaccination schedule and we will wait it out. You can always claim a religious/philosophical exemption when signing your child up for school. Best of luck to you!
