Key result
The introduction of the IPV polio vaccination schedule maintained high population immunity, with ≥95% seroprevalence to poliovirus types 1 and 2 and ≥94% to type 3 among preschool children.

Does the change from OPV to an OPV/IPV sequential schedule impact population immunity to polioviruses in low-income preschool children?
The transition from OPV to an OPV/IPV sequential schedule maintained high population immunity against polioviruses in underserved urban preschool children.
Prevots et al. (2004) conducted a cross-sectional in Polio immunity. Inactivated poliovirus vaccine (IPV) introduction was evaluated on Seroprevalence of neutralizing antibodies to polioviruses types 1, 2 and 3. The introduction of the IPV polio vaccination schedule maintained high population immunity, with ≥95% seroprevalence to poliovirus types 1 and 2 and ≥94% to type 3 among preschool children.
