Definition Vaccination coverage rate for polio-3 is the proportion of surviving infants who received three doses of oral polio vaccine before their first birthday. Polio is an epidemic viral infection which attack s the motor meurons of the anterior horns in the brain stem and spinal cord, the effects of which are crippling.

Notes Regional averages are weighted by the population under one year of age. Note that regional averages are higher in years for which there are no data for Haiti. OPV-3 is a four-dose schedule (the first dose is considered & quot;0") for children resulting in lifelong immunity to the poliovirus. As the third dose signifies the completion of the series, this dose is used to estimate coverage rates.

The estimate of vaccination coverage rates is used to measure the ability of a country to provide universal child immunization. The World Summit goal for immunization is the maintenance of 90 percent coverage among children under 1 yea r of age. While the Americas have been certified "polio-free" the vaccination of children with OPV continues until the disease is eradicated from the entire world, due to the possibility of the poliovirus being brought into the region from a no npolio-free region.
