Not always true, my vaccinated daughter got chickenpox from an unvaccinated child.

So, we would have to conclude that the chicken-pox vaccine is exactly how useful?

And therefore, why is the vaccine preferable to actually getting the disease, which—unlike the vaccine—effectively confers immunity to future infection?

Chicken Pox Vaccine is worthless all it does is ensure that most kids will now get it when they are older and males in particular will risk sterility because of it.

Its only 70% effective at best, and its not lifetime immunity.

Wrong again, FRiend. Getting the disease does not actually confer long-term immunity. Shingles is adult-onset chicken pox. Lots of people get it who had chicken pox as kids.

And Hep B is not only something IV drug users and fags get. Anyone who is exposed to infected blood or fecal matter can get it, like at your local fast food joint, grocery store, or school.
