We have been considering this also as my husband had a Bone Marrow Transplant in Oct. The Drs @ UofM recommend all of them. We have considered herd immunity and his age. We are looking into how many people in our community have had each of the diseases and for now we have opted to postpone any vax for him. Now obviously you have a young child and school to consider. My kids are child bearing age and I would encourage them to research everything and not let one side or the other pressure you into a decision. This is your child and your responsibility. You are raising this child in a very different time then another time in history. Politely listen to all input but realize you and your child will be dealing with the result if your decision is wrong. I taught my children a process for overall decision making. Pm me if you're interested in that process.
