Y1 - 2023 N1 - T2 - Current Medical Diagnosis & Treatment 2023 AB - A novel oral polio vaccine type 2 (nOPV2) has been developed in response to the ongoing circulating vaccine-derived type 2 poliovirus outbreaks and has been shown to be safe and immunogenic in previously immunized adults. Studies have shown that nOPV2 is more genetically stable than the mOPV2 and therefore less prone to reverting to neurovirulence. The nOPV2 was recommended for initial use under the World Health Organization’s Emergency Use Listing Procedure in November 2020.
