Vaccines provide temporary protection from certain acute illnesses. Acute illness, is by definition, self-limiting. They are short term. Chronic illness goes on and on and on. Since nature has given us acute illnesses, there is a reason that we get them. For children, it is pretty clear that they need to exercise their immune system. Studies have been done which reveal that when parents keep the house too clean, kids don’t develop a strong enough immune system to fight off the bad boys when they come around. In fact, some believe that it is a source of autoimmune disorders, asthma, and allergies, because the body doesn’t know what needs to be fought off and what doesn’t.
Vaccines are given to healthy children in order to protect them from getting sick. The vaccine-preventable diseases, while wide spread, rarely caused complications. The same can't be said for the chronic diseases that have replaced the acute illnesses.
