An Interesting Article about Vaccinations and Health

I found this article quite interesting. I have never seen a complication of a common vaccination. I have, however, seen several patients who had serious complications of vaccine preventable diseases.

Before vaccines and common hygiene, children were exposed to many diseases when they were very young; often less than 6 months old. They commonly had their mother's immunity transmitted in utero and breast milk, so developed their own antibodies without major illness. A good example of this was polio, which became a serious health issue only when children under 6 months old were no longer exposed to the virus (which is present in human waste) as society developed sewers.
