As part of the global poliovirus eradication strategy, oral poliovirus vaccine (OPV) has successfully contributed to reduce polio incidence rates globally. However, because of the OPV-related risks of vaccine associated paralytic poliomyelitis (VAPP) and vaccine-derived polioviruses (VDPVs) OPV cessation is required in order to achieve complete eradication of polio. Inactivated poliovirus vaccine (IPV) is a viable option for incorporation into existing vaccination schedules so as to avoid these risks. Furthermore, the continuation of vaccination with IPV will protect populations in case of re-emergence of wild-type poliovirus from remote locations, laboratory samples, or through bioterrorism. The ability of IPV to prevent poliovirus outbreaks and provide herd protection has been demonstrated in several circumstances and in various settings. This paper reviews clinical experiences with IPV administration and outcomes in various countries in Europe, the Americas, Africa and Asia.

Introduction: following the detection of vaccine-derived poliovirus in 2019 in Ethiopia, response activities have been conducted including strengthening disease surveillance activities.
Methods: trend analysis study design of acute flaccid paralysis and measles surveillance data for the years 2021 and 2022 for Southwest Ethiopia Region was used. The non-polio acute flaccid paralysis (AFP) rate and stool adequacy rates were used to assess the AFP surveillance.

Background: Polio, a debeilitating and potentially life-threatening disease, continues to pose a risk to young children globally. While vaccination offers a powerful shield, its reach is not always equal. This study explores socioeconomic and geographical inequalities in polio immunisation coverage among two-year-olds in Sierra Leone between 2008 and 2019.

Enteroviruses (EV) are a highly diverse group of viruses multiplying primarily in the gastrointestinal tract and/or the upper respiratory tract, initially distributed in two separate genera: Enterovirus and Rhinovirus, respectively. According to the similarities in genome organization and particle structure, rhinovirus species were later reclassified as also belonging to genus Enterovirus. Human EV infections are usually asymptomatic or causing mild clinical manifestations.

The coronavirus disease 2019 (COVID-19) pandemic has disrupted polio immunization programs worldwide. The consequences of these programs' suspension were not fully presented during the COVID-19 pandemic, as some take time to present in a population. We conducted a narrative review to provide a perspective of current literature on the effect of the COVID-19 pandemic on efforts made for poliomyelitis eradication.
