At present, the risk of increased circulation of vaccine-related polioviruses and associated outbreaks with a low level of vaccination coverage against the background of the use of an oral vaccine is also complicated by military operations in the country, leading to the destruction of the infrastructure of cities and towns, intensive migration and evacuation of the population. Ukraine, and to regions where there are no active hostilities (Chernivtsi, Transcarpathian, Lvov, Volyn regions). These areas were the ones with the lowest polio vaccination rates in 2021.
It is the transition to the use of IPV in Ukraine for all doses of the Immunization Schedule that should be the next task for vaccination. For this, several mechanisms can be used, including humanitarian assistance, the conclusion of planned direct contracts with vaccine manufacturers based on the needs of the required composition of vaccines according to the Calendar, in particular, taking into account the existence of modern combined vaccines with IPV, which can also be used at an older age. In the absence of combination vaccines with IPV, IPV can be used as a single vaccine.
Considering that a similar picture took place in previous years, in Ukraine there was an accumulation of a layer susceptible to poliomyelitis among the child population. In addition, since April 2016, the oral (live) polio vaccine (OPV), which is used in Ukraine, since the 3rd vaccination, does not contain type 2 poliovirus (two-component OPV, which is now used worldwide, contains only polioviruses). ). type ov1 and 3). This also contributes to a decrease in both individual and population immunity to type 2 poliovirus. The result was an outbreak of poliomyelitis caused by vaccine-derived type 2 poliovirus (a vaccine-derived virus that acquired neurovirulent properties during circulation in a low immune population.). There was no adequate response to this outbreak, namely additional vaccination rounds for children under 6 years of age to stop the circulation of the vaccine-related virus. In January 2022, a new outbreak emerged.
Именно переход на использование в Украине ИПВ для всех доз Календаря прививок должен быть ближайшей задачей по вакцинопрофилактике. Для этого можно использовать несколько механизмов, включая гуманитарную помощь, заключение планируемых прямых договоров с производителями вакцин исходя из потребностей необходимого состава вакцин согласно Календарю, в частности с учетом существования современных комбинированных вакцин с ИПВ, которые могут быть использованы и в более старшем возрасте. При отсутствии комбинированных вакцин с ИПВ можно использовать ИПВ в качестве моновакцины.
