OURTorah, good point.
Anti-vaxxers, have you every seen the permanent and life altering effects of polio on a person? My mother had to live the city in the summer because of the fear of getting polio. If you polio is dead, it still exists in other parts of the world and if it comes to USA or Israel, are you ready to accept responsibility for your children getting polio or its terrible effects? I would not and could not.
