This is mainly shown for VDPV type 2. Here we describe a molecular-epidemiological investigation of a case of VDPV type 3 circulation leading to paralytic poliomyelitis in a child in an orphanage, where OPV has not been used. Samples of feces and blood serum from the patient and 52 contacts from the same orphanage were collected twice and investigated. The complete genome sequencing was performed for five polioviruses isolated from the patient and three contact children. The level of divergence of the genomes of the isolates corresponded to approximately 9\u201310 months of evolution. The presence of 61 common substitutions in all isolates indicated a common intermediate progenitor. The possibility of VDPV3 transmission from the excretor to susceptible recipients (unvaccinated against polio or vaccinated with inactivated poliovirus vaccine, IPV) with subsequent circulation in a closed children\u2019s group was demonstrated. The study of the blood sera of orphanage residents at least twice vaccinated with IPV revealed the absence of neutralizing antibodies against at least two poliovirus serotypes in almost 20% of children. Therefore, a complete rejection of OPV vaccination can lead to a critical decrease in collective immunity level. The development of new poliovirus vaccines that create mucosal immunity for the adequate replacement of OPV from Sabin strains is necessary.<\/jats:p>","DOI":"10.3390\/v12090970","type":"journal-article","created":{"date-parts":[[2020,9,1]],"date-time":"2020-09-01T14:21:10Z","timestamp":1598970070000},"page":"970","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Case of Poliomyelitis Caused by Significantly Diverged Derivative of the Poliovirus Type 3 Vaccine Sabin Strain Circulating in the Orphanage"],"prefix":"10.3390","volume":"12","author":[{"given":"Ekaterina A.","family":"Korotkova","sequence":"first","affiliation":[{"name":"Belozersky Institute of Physical-Chemical Biology, Lomonosov Moscow State University, 119899 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5630-3471","authenticated-orcid":false,"given":"Maria A.","family":"Prostova","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anatoly P.","family":"Gmyl","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"},{"name":"Institute for Bionic Technologies and Engineering, Sechenov First Moscow State Medical University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liubov I.","family":"Kozlovskaya","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"},{"name":"Institute for Bionic Technologies and Engineering, Sechenov First Moscow State Medical University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatiana P.","family":"Eremeeva","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga Y.","family":"Baikova","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandr Y.","family":"Krasota","sequence":"additional","affiliation":[{"name":"Belozersky Institute of Physical-Chemical Biology, Lomonosov Moscow State University, 119899 Moscow, Russia"},{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadezhda S.","family":"Morozova","sequence":"additional","affiliation":[{"name":"Federal Centre of Hygiene and Epidemiology, Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing, 117105 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1784-4827","authenticated-orcid":false,"given":"Olga E.","family":"Ivanova","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Scientific Institution \u201cChumakov Federal Scientific Centre for Research and Development of Immune-and-Biological Products of the Russian Academy of Sciences\u201d (FSBSI \u201cChumakov FSC R&amp;D IBP RAS\u201d), 108819 Moscow, Russia"},{"name":"Institute for Bionic Technologies and Engineering, Sechenov First Moscow State Medical University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,1]]},"reference":[{"key":"ref_1","unstructured":"Plotkin, S.A., Orenstein, W.A., Offit, P.A., and Edwards, K.M.
