Yeah, I don't wanna hear shit about chickenpox being good for a child. I was too young to be able to get the vaccine and because of that, there's a chance I get the complications of getting pox that you get later in life. It wasn't even my own parents fault, since I caught it in daycare.

Also, if I remember correctly, Japan rolled out the first chickenpox vaccines to prevent it from becoming a mass epidemic on their island nation.

Edit:

It's shingles. That's the complication that can happen later in life after having pox.
