Both of mine have been vaxxed - there was an outbreak of CP which was particularly nasty when DD1 was in kinder and some kids got very sick with lots of spots. A number ended up with scars on their faces from it. DD1 must has also contracted it. She had 2 spots, one on her scalp (the only reason we know it was CP for sure as the GP said that CP is the only virus that blisters the scalp) and one on her chest. She has a scar on her chest from the one that was there. DD2 didn't contract it at all.

I guess my point is that the non-vaxxed kids had a much worse dose than any of the vaxxed kids if they caught it and ended up with some nasty scars because of it.
