Bx, as far as I know locally, there have been some cases around here in the past few years of children getting c-pox even if vaccinated and the odd case of shingles in adults (some of which have also had c-pox). Don't get me wrong, I"m not against vaccination by what I've said - heck I have 3 vaccinated children and a baby who was vacced till 6mths, I am choosing not to vaccinate any further for any of them. You just can't assume that even vaxed people are safe or wont become carriers is all my issue was in relation to the OP's 'theory' so I don't have links, just my mind thinking overtime . I won't be relying on herd immunity either because I think that's a pretty poor and lazy way to choose not to vacinate.

And since the chicken pox vaccine has been brought into the discussion, I have come full circle on that one. I was a staunch supporter of it and had my older three vaccinated for it even though it wasn't on the schedule for them, but in light of my own research I don't think it gives a strong enough protection for long enough.
