>  My youngest child has never been immunized.

I suppose if you live in a nice middle-class area, the risk of hepatitis in
the schools is insignificant. Polio may be another matter. I don't know, I'm
just speculating. You might want to consult with the public health agency in
your area as to the risk there.

I'm a few days short of 50. When I was a kid back in Jersey City, NJ, there
were times in the summer when the municipal swimming pools were closed
because of the risk of polio contagion. Polio was not a theoretical risk. It
made the headlines in the daily papers. News stories about paralyzed kids in
wheelchairs or strugglong to walk with crutches and braces were not
uncommon. My mother told me that I almost died of whooping cough (pertussis)
as an infant; that vaccine was not yet available.

I got my first polio immunization by injection when the Salk vaccine
appeared. I recall (dimly) the excitement and relief that its introduction
caused. The introduction of the oral vaccine was also a significant and
welcome event in our lives then.

Polio is a sinister disease. Adults who had polio as kids and seemed to have
stabilized are now experiencing a resurgence and worsening of symptoms.

Dr. D'Adamo discusses vaccines, and specifically polio vaccines, on pages
235-236 of his book. He recommends the oral vaccine for kids with blood
types O and B, and the injectoble form for types A and AB.

There is certainly a risk to immunization. I believe the early polio vaccine
caused polio in some cases. I don't know if that's still the case. However,
polio is such a bad disease that even if the risk of contracting it is
small, immunization is on balance by far the better choice.
