[Boogieman]

So if your kid has a malformed heart valve, and doctors can fix it, but there is a 1% chance he will die during surgery, or a 50% chance he will die in the next 10 years without the surgery, you would choose just to pray and withhold medical care for the child?

[Jan_Sobieski]

I would do the heart valve repair.

Your example is the fallacy of conflation. Your argument assumes that there is something wrong with the child prior to receiving the vaccination. Or that the child is somehow incomplete without receiving the vaccination.
