You can get chicken pox twice.
I dunno about chicken pox parties any more....
As nsdog said my lot had it last summer after we were just casual about the association with our friends kids who had it. We didn't want to spoil the ride/pub thing with kids in tow we were all planning to go on when one mate discovered his kids had it. So we all went anyway.
I guess I came to regret it as my little baby came a bit too close for comfort, they said after that if they had not have got her on intravenous antibiotics when they did then within a few hours it may have been too late.
Knowing what I know now, I would have paid for the vaccine. But I am a bit precious over my kids..
She's fine now apart from some scars. (she still has eczema, not so bad, but she is constantly slathered in grease of one kind or another and has to have greasy hair shampoo stuff). You can see what that big one on the left of her forehead left behind. (5 months between pics, although now at 7 months the scar looks the same)
