Special Issue Information

Dear Colleagues,

The discovery of two vaccines against poliomyelitis—first the inactivated poliovirus vaccine (IPV) created by Jonas Salk, and soon after the live oral poliovirus vaccine (OPV) by Albert Sabin—was an enormous medical breakthrough of the mid-20th century. Their creation and use established a paradigm for other vaccines. Their evolution over the more than 60 years since their introduction is a perfect illustration of the need to continuously update medical products to match the changing epidemiological, economical, and societal landscape. OPV was so successful that in 1988, the World Health Assembly resolved to completely eradicate poliomyelitis by the year 2000. Even though the deadline was not met and polio eradication remains a moving target 35 years later, the Global Polio Eradication Initiative achieved tremendous progress. It also became clear that the current versions of IPV and OPV are not optimal for a post-eradication world. IPV is made from highly virulent virus strains and does not prevent virus transmission. OPV causes rare but serious adverse events and can trigger new outbreaks caused by a vaccine-derived virus. Therefore, finishing the eradication campaign and making its success irreversible requires the development and introduction of a new generation of polio vaccines. This Special Issue is devoted to these ongoing efforts.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract
The widespread use of the oral poliovaccine from Sabin strains (tOPV) radically reduced poliomyelitis incidence worldwide. However, OPV became a source of neurovirulent vaccine-derived polioviruses (VDPVs). Currently, circulating type 2 VDPVs (cVDPV2) are the leading cause of poliomyelitis.

The widespread use of the oral poliovaccine from Sabin strains (tOPV) radically reduced poliomyelitis incidence worldwide. However, OPV became a source of neurovirulent vaccine-derived polioviruses (VDPVs). Currently, circulating type 2 VDPVs (cVDPV2) are the leading cause of poliomyelitis. The novel OPV type 2 vaccine (nOPV2), based on genetically modified Sabin strain with increased genetic stability and reduced risk of cVDPV formation, has been used to combat cVDPV2 outbreaks, including one in Tajikistan in 2021. In order to identify the importation of cVDPV2 and nOPV2-derivates, stool samples from 12,127 healthy migrant children under 5 years of age arriving from Tajikistan were examined in Russia (March 2021–April 2022). Viruses were isolated in cell culture and identified via intratype differentiation RT-PCR, VP1 and whole-genome sequencing. cVDPV2 isolates closely related with the Tajikistan one were isolated from two children, and nOPV2-derived viruses were detected in specimens from 106 children from 37 regions of Russia. The duration of nOPV2 excretion ranged from 24 to 124 days post-vaccination. nOPV2 isolates contained 27 mutations per genome (0.36%) on average, with no critical genetic changes, which confirms the genetic stability of nOPV2 during field use. The possibility of epidemiologically significant poliovirus introduction into polio-free countries has been confirmed. The screening of special populations, including migrants, is required to maintain epidemiological well-being. Full article
