of the polio vaccine, it's my pleasant duty to report to you the results of polio vaccinations today and the findings of the effectiveness of the vaccine. here is a very simple chart which indicates how the vaccine works during 1955. it's based on reports from 22 states and new york city among vaccinated children as you can see, the attack for polio was only 6.3 per 100,000. follow on the unvaccinated, the attack rate was 29.2 per 100,000. almost four times as high. the studies involved about 8.5 million women and children whose ages range from 5 to 11 years even though most of the vaccinated children had only one instead of the full dosage of three, the vaccine was found to be about 78% effective.

put another way, the boys and girls received at least one injection of vaccine at about four times as much protection as those without it. we can all be proud of the vaccine but you can all share in the hope that this is a victory. >> for maximum protection of paralytic polio, three inoculations the second not less than two weeks after the first, the third not less than seven months later. your child or anyone else eligible in your community should be vaccinated now. vaccination now will save lives from death or paralysis this year. make use of increasing supplies of vaccine, help your child grow up strong and straight, free from crippling polio. youngsters like david eisenhower, like polio pioneer randy
