From the second page" Contracting the polio virus secondhandedly isn't always helpful. It's helpful if the virus contracted is still weakened. However, the virus in the feces might become wild and dangerous. Instead of being a weakened polio virus, it could become a regular polio virus. Instead of becoming immune to the virus, you would have the virus and become infected with polio. This deviates from the purpose of the vaccine, which is to prevent, not cause, polio."

"Others are ``contact'' polio cases -- usually other kids, relatives or caretakers who contracted it from children taking the oral vaccine dose, and then passing on the disease unintentionally by ``shedding'' the live virus through their feces or body fluids."

"Only 1 in 12 million children who take the oral polio vaccine develop the disease from it. A quarter of the unlucky victims are, like David, born with immune disorders that take about a year to emerge. Until then, parents and doctors have no reason to believe the children are at risk.
"The rest include infants who catch the vaccine virus from other children, often siblings, who were recently vaccinated. There have even been adults, including Lt. Gov. John H. Hager of Virginia, who contracted polio while changing a baby's diapers."

"For example, a parent can become infected by an infant during diaper changes, or improper waste disposal can lead to contamination of a water supply. These infections, in turn, will spread the virus more widely." |
