You are more likely to die by being burned to death from a home cooked meal than you are from chicken pox. If your goal is to protect children, your efforts would be better spent having kitchens banned from homes, as well as the cooking that happens in them.
What an idiotic comparison. If I could be protected from getting burned in the kitchen by a simple vaccine, I'd take that too.
We don't know whether getting vaccinated against chicken pox protects against children, because the varicella vaccine was introduced in 1995, so nobody vaccinated against chicken pox as a child has yet reached the age of high risk to shingles.
Prior to vaccination, there were thousands of hospitalizations and over a hundred deaths yearly from chicken pox. There is not a single documented death from the vaccination, and serious reactions are extraordinarily rare.
There is no actual evidence to support the notion that vaccination pushes infection off to adulthood, when it is more severe. In fact, the statistics show a precipitous fall in hospitalizations and deaths from chicken pox since the vaccine's introduction.
If you are concerned about vaccine protection wearing off, the solution is give everybody a booster, not to skip vaccination. Boosters probably aren't necessary so long as the great mass of the population is vaccinated at birth, since herd immunity makes it unlikely that adults will ever encounter the virus.
