Your reasoning does not make sense. If you get chickenpox as a child, you should have lifelong immunity to chickenpox. You will have a risk for shingles as you get older, and there is a vaccine you can take to prevent shingles. If you do get shingles, in most cases it is not life threatening.
However, if you get the chicken pox vaccination as a child, you run the high risk of losing immunity as an adult. How many adults in the age 30-50 range get vaccinations? None. They are too busy working and raising a family. The vaccine could wear off, just like we saw with smallpox. There is no statistics yet for duration of the chickenpox vaccine, because it is new. But there is quite a bit of speculation that the immunity wears off as you get older. You can die if you get chickenpox as an adult.
I would rather my kids ( which I do not have, but if I did) get chickenpox than take the vaccine. If the herd immunity is too strong, then I would vaccinate them at age 17.
I think in the long run, we are going to see decreasing immunity, adults too busy to get re vaccinated, and death from chickenpox.

Well, talk to your doctor if this does not make sense. A virus lives on within you, but your immune system keeps it under control. Compromise that immunity with stress, a bad cold, etc…

Well, do you know anyone with the herpes virus that causes cold sores on the lips? Obviously, having a virus does not create permanent immunity.

IOW, maybe consider getting the shingles vaccine.

All vaccines have a certain rate of losing effectiveness over time--some more than others.

Leave your expectations of perfection to heaven.

Do with your children as you will. God help them...
