Like I said, not so long ago I stood where you are now, facing this same decision. And I can share that my wife and I made the choice to vaccinate. We were living in Africa at the time, at perhaps that weighed into our decision as well, but ultimately we felt that each individual in society has to risk a little bit and be willing to make some personal sacrifices in order to maintain / advance the health and welfare of the society in which they live.
We vaccinated our son knowing that he could have a random, but acutely adverse reaction to the vaccines. It does not mean that we loved him any less for having taken that chance. It just means that we felt it is one of the many sacrifices that we (and he) would necessarily have to make in order to offset our own negligence and sense of entitlement and try and work in unison and harmony with the society around us. We have many close friends who are motivated by and strive for the same goal (very succesfully, I might add), but have made the choice not to vaccinate their children. That choice has not fouled our friendship.
Thankfully, there are no *apparent* and *obvious* that the vaccines have caused any problems, but I'm not foolish enough to think that even if they had/have caused any, the problems would manifest themselves immediately or openly. The whole upstir here-and-there trying to connect vaccines with autism and the like is, for an example, continues to be a constant worry for me.
And I want to clarify that I'm not implying that you or your wife are "free riders". I am just pointing out that your actions might bring that stigmatic label with them. FWIW, to me, The fact that you're giving a lot of thought and consideration to the choice you face here (just as with the home-schooling issue) is an indication (to me, anyway) of your earnest desire, as parents, to give your kids the best possible shot (
) at a healthy and productive life as beneficial members of society. I think that's highly commendable and I, for one, applaud you for that. I only wish that all children had parents, like you two, who cared for them as much as to so earnestly reflect on the choices that are made on their behalf.
