Life can never be made risk free, pain free, illness free, or death free.
I am all for people getting to choose whether or not to vaccinate themselves or their children.
If people understood the risks of diseases, they would understand the blessings of vaccines. E.G. Many people seem to think that tetanus is contagious and not more risky than chicken pox. As you probably know, tetanus is contracted from wounds such as pricks while gardening. It is still >50% fatal. A person w/ tetanus experiences such severe muscle spasms that sometimes the back of their head can touch their heels -- causing spinal fractures.
Now let informed people make the choice. While most kids shake off chicken pox and measles there are many side effects & sequelae that are not pretty.
