Types 1 and 3 OPV cessation is likely expected in 2020-2022, i.e. 1-2 years after certification of global interruption of wild poliovirus transmission. After cessation of bOPV, IPV will be used for routine polio vaccination for 5-10 years.Recently, SAGE recommended that IPV be used after global OPV withdrawal with an IPV schedule that achieves at least 90% seroconversion with two full or fractional doses. SAGE has recommended that the first dose be administered after 14 weeks of age and an interval of at least 4 months between two IPV doses. In the proposed clinical trial, immunogenicity of two IPV doses with schedules that are likely to achieve 90% immune response to all poliovirus types is being assessed to inform SAGE policy deliberations on potential IPV schedules after OPV cessation. A head-to-head comparison of different IPV schedules is important to determine the immunogenicity of the schedules under similar conditions and evaluate the differences in population immunity, a product of immunogenicity and vaccination coverage, with the different IPV schedules.
