Polio in Israel and Vaccination
Polio virus from the oral vaccine is spread through the stool, so the most common mode of transmission is from changing diapers of recently vaccinated babies. Adequate handwashing in older children or adults who have been recently vaccinated will help prevent infections. If you have read the section in my book The Vaccine Guide you know that more than 95 % of people who contract the polio virus experience only cold symptoms, and many people who have had the virus or shed the virus just have a cold. In some unvaccinated communities nearly all of the children have been found to carry antibodies to polio, which means they have been exposed to wild polio or the live vaccine virus spread by others and none of them developed nervous system symptoms.
