I was excited when they came out with the varicella/chicken pox vaccination just before my son went to school.
I told him all about the pox all over my body, even in my nose and throat that itched so badly, but you couldn't scratch them in order to avoid scars. I have one scar on my forehead from a pox that was just crazy itchy.
He asked if all the kids actually got a nasty disease like this and I told him, "Pretty much so. You'd have to stay out of school for a week or so, being low grade feverish, so itchy you can hardly stand it. Calamine lotion helped dry up the blisters but it's a very mild treatment. So your week at home was not even fun.
He needed another shot and he never caught chicken pox, thank God !
