Similarity between the expected global number of paralytic WPV1 (left panel) and cVDPV2 (right panel) cases by year for 100 stochastic iterations of the “mOPV2, current oSIA” scenario for 2016–2021 (dashed lines) compared to the deterministic reference case (RC, solid lines). In all modeled scenarios, IPV is used in RI in all countries as a prerequisite to OPV cessation. The actual number of reported cases are shown in solid bars for reference.
