Hi, Gcharles,
As I see it, life is a series of trade-offs. People select what they want based on the information they are given. In the case of immunizations there are many organisms out there that will ruin either your day, or the days of your children. When you look at the numbers - and the published reports (here is one from the CDC:
cdc.gov/vaccines/vac-gen/why.htm ) it is a good idea to avoid these very real problems that impact millions throughout the world - take that risk, rather then avoid the real but statistically insignificant risk of an adverse reaction from the immunization. Those who elect to avoid the immunization essentially allow themselves to be part of a pool that the diseases can grow in… insuring that the orgnism remains.
We chose to drive - knowing that the odds of dying in a motor vehicle accident (MVA) are much greater then dying at home. If we want to have a life outside of our home, we take the necessary precautions (mechanically functioning car, wearing seat belts, not driving impaired, obeying the posted signs, etc.) Now, it is understood that even doing all of these things is no guarantee that you will not die or be injured in a MVA - but, most people do these things because it greatly incrases the odds at arriving at your destination safely.
I am not arguing about mercury or any other element in a vaccination. FDA has determined it is safe for the vast majority - but, there are risks. This is part of the real world - right up there with disease. I find it odd that the parents who are preventing their children for getting vaccinated - were themselves vaccinated (and therefore protected) from the disease that they want their own children to have exposure. Maybe the vaccination makers did too good of a job - just not enough morbidity and mortality around to convince people that avoid problems is so much better then trying to cure them.
It is out there, it is real and it is dangerous - you decide which one you want and then act accordingly.
God bless
