Do parents need to expose their kids in a "chickenpox party' for immunity building?

I would personally expose my child to chickenpox and all the other so called children's illnesses(and in fact have) it is better to risk getting them and building up an immunity to them whilst young, chickenpox can leave teenage boys sterile if they suffer from complications with it and most of the others can be more serious illnesses when you are older. But i also have had my daughter vaccinated but not all vacinations are succesful so it does not hurt sending them to chicken pox parties many doctors still advise both. I am afraid you will always find someone to agree with a particular point of view so you just have to learn all you can and make up your own mind, but I do agree that the complications of these childhood disease can be horrendous and even death can occur soI would always advise vacinations and exposure just to be sure
