I held off on Jacks and will give it to him around 10 years, childhood chicken pox usually isn't to bad...the vaccine only lasts 10 years so they will need a booster in their teens

not to freak you out or sway you either way..chicken pox is the only one I have a problem with ok

but in its either Japan or china I think its japan google it you will find the article...have been vacinating for 25 + years and they are finding above average hugely so incidents of shingle in people in late teens early 20's who were all vaccinated and haven't had chciken pox

now you normally only get shingle if you have had chicken pox and then normally after you 50's

so something to think about
