A way of phasing it in perhaps? Does it last forever?
Surprised there is one. I thought you got immunity to chicken pox through having it, but the dormant virus kicks off and gives you shingles? Or is that a mutation that needs a different vaccine? I'll Google it, sorry.
Edit.
Same virus apparently. The vaccine just boosts your immunity if you've had chicken pox. If you haven't, and you come into contact with the virus, it will stop you getting chicken pox instead I suppose.
