Are you sure about that? The CDC suggests many similar complications (which would cost exactly the same to treat regardless of the genesis of them) according to their website and indicates [mostly un-vaccinated] people die from chickenpox too. The comparison surprised me too, but seems to be remarkably appropriate.

I'm sure. Chickenpox was a "universal illness" -- everyone was exposed, but only a small fraction developed severe illness or died.
