Polio Eradication Officer Question:

To stop polio transmission no less than 95% of all children of Pakistan should be immunized during each campaign. To achieve this high coverage is very challenging logistically. In other words, the remaining 5% that make almost 2 million unimmunized children should be reached during consecutive campaigns in a short interval to ensure all children are covered. Furthermore, once the polio virus is detected in a certain area, an additional campaign will be carried out for that district to prevent potential outbreak of polio amongst children in the community. That is why multiple polio campaigns are done every year. No child should miss a single dose of polio vaccine! Each additional dose is an additional protection against polio
