The circulation of these variants within under-immunized populations leads to the further evolution of circulating, vaccine-derived poliovirus with increased transmission capacity, representing a significant risk of polio re-emergence. Although the wild poliovirus type 2 (WPV2) had been declared as eradicated worldwide in 2015, outbreaks of circulating VDPV-type 2 (cVDPV2) have been increasingly reported, especially after the tOPV-bOPV switch that occurred in 2016, which resulted in building a cohort of susceptible individuals with lower type 2 intestinal immunity. Since the response to outbreaks is done through conducting supplementary immunization activities (SIAs) using type-2 containing OPV, this carries a risk of mutations, especially with suboptimum coverage and potential further circulation. The recent detection of outbreaks of cVDPV2 in some countries necessitated the development of a genetically stable novel oral polio vaccine type 2 (nOPV-2) to decrease the chances of mutations and hence outbreaks.
