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.

В настоящее время риск усиления циркуляции вакцинородственных полиовирусов и связанных с ними вспышек при низком уровне охвата прививками на фоне применения оральной вакцины осложняется еще и военными действиями в стране, приводящими к разрушению инфраструктур городов и населенных пунктов, интенсивной миграции и эвакуации населения. Украины, так и в регионы, где отсутствуют активные боевые действия (Черновицкая, Закарпатская, Львовская, Волынская обл.). Именно в этих областях отмечались самые низкие уровни вакцинации против полиомиелита в 2021 году.

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.

Treatment with corticosteroids (especially prednisolone ≥20 mg/day or equivalent) is associated with an increased risk of infection. However, it is unclear whether corticosteroid therapy is associated with an increased risk of developing COVID-19 or its complications. Data on budesonide, a topical corticosteroid with low systemic bioavailability, show that these drugs are associated with significantly fewer side effects compared to systemic corticosteroids and their side effects are close to placebo. If possible, corticosteroids should be avoided and a rapid dose reduction considered, and a switch to budesonide is recommended. This must be taken into account, taking into account the risk of exacerbation of CKD. If a patient with COPD is in contact with a person with COVID-19 or develops COVID-19, it is recommended to gradually reduce the dose of corticosteroids, the use of budesonide is preferred, but taking into account the severity of COPD and the risk of exacerbation.
