Relevance. According to scientific publications, preventive measures undertaken amid the COVID-19 pandemic failed to did reliably protect healthcare workers from the new coronavirus infection. The use of personal protective equipment (PPE) that protected against biological factors failed to protect HCWs from becoming infected and in most cases contributed to the functional disorders and impaired health. The objective is to provide evidence-based justification of preventive measures aimed at increasing healthcare workers’ (HCW) safety by using PPE during elimination of biological and social emergencies (based on the case of the COVID-19 pandemic).Methods. The study design included four consecutive stages: occupational morbidity assessment for COVID-19, assessment of HCWs’ working conditions; assessment of HCWs’ safety when using PPE sets in real setting and simulation, and justification of preventive measures to improve safety of HCWs.Results and discussion. The first year of the COVID-19 pandemic saw the incidence of 30.4 % among all HCWs working at the Military Medical Academy, suggesting a high risk of infection transmission. Morbidity was utmost among HCWs specializing in infections, followed by a significant number of HCWs who do not work in contaminated areas on a daily basis (surgeons, urologists, traumatologists). In addition to high incidence rate, the new coronavirus infection pandemic demanded enforcement of specific measures associated with the use of PPE at increased physical stress, including amid elevated ambient temperature. A sociological survey and experimental data allowed to assess the risk of functional and heat-injury related health disorders, as well as injuries in HCWs using PPEs. In order to reinforce occupational safety and minimize occupational risks of health deterioration in HCWs wearing PPEs at work, the research results allowed to develop a two-stage preventive action plan: stage 1 includes identification of dangerous factors, whereas stage 2 focuses on preventive measures to eliminate negative impact of hazards and associated risks.Conclusion. A set of preventive measures developed for the COVID-19 pandemic suggests practical tools to reinforce occupational safety for HCWs who use PPEs to deliver biological and social emergency response and elimination.

Introduction. Diseases of cardiovascular system are the leading causes of morbidity and mortality among the able-bodied population. There have been no studies of the impact of the COVID-19 epidemic on cardiovascular mortality in Russian Railways. The study aims to analyze the mortality of Russian Railways employees from diseases of the circulatory system during the COVID-19 pandemic with the working-age population of the Russian Federation. Materials and methods. The study was carried out on the basis of data obtained during the COVID-19 pandemic (2019-2021). Information on the mortality of employees of JSC "Russian Railways" is formed on the basis of the data of the CHUZ of JSC "Russian Railways". Information about the natural movement of the working-age population was formed on the basis of data from the Unified State Register of Civil Status Records. Results. During the pandemic, the mortality rate in JSC "Russian Railways" was 2.2 times lower compared to the working-age population of the country. Excess mortality by road polygons was different. The maximum mortality rate (3.4 per 1000 employees) was among employees of enterprises of central subordination, the minimum (2.1) was on the Northern Railway. 82.5% of deaths occurred in men, while the mortality rate among men is 2 times higher compared to women. The main cause of death of workers were diseases of the circulatory system (BSC) - 28.7%. The mortality rate from BSK in JSC "Russian Railways" was 0.656, which is 2.9 times lower than for the working-age population of Russia. Conclusion. The study showed that under the conditions of a new coronavirus infection, the mortality rate from circulatory system diseases in Russian Railways employees is lower than in working-age population of Russia. Ethics. We have carried out this study in accordance with the rules of good clinical practice and the Helsinki Declaration. The study did not require the conclusion of the Ethics committee.

Relevance. The effectiveness of vaccination of the working population against COVID-19 in the Russian background has not been studied enough.Aim. To evaluate the effectiveness of vaccination of the working population with Gam-COVID-Vak (Sputnik V) in the Russian Railways as an example.Materials & Methods.The effectiveness of vaccination with Sputnik V among employees of Russian Railways in the period from January 21 to November 31, 2021 was performed with the Cox regression method.Results. The effectiveness of Sputnik V against COVID-19 infection with was 97.8% (95% CI 97.8–97.9%) for two doses, 91.9% (95% CI 91.6–92.2%) for a single dose, and 97.9% (95% CI 97.6–98.1%) for revaccination, all after socio-demographic factors adjusted. The effectiveness of vaccination against COVID-19 with hospitalization was 97.5% for two doses of Sputnik V (95% CI 97.1–97.9%), 86.1% (95% CI 83.7–88.1%) for a single dose, and 98.2% (95% CI 96.3–99.2%) for revaccination. The effectiveness against lethal COVID-19 was 95.2% (95% CI 93.1–96.6%) for two doses of Sputnik V and 94.8% (95% CI 89–97.6%) for one dose. The high efficiency of vaccination could be associated with a fairly young age composition of the employees of the Russian Railways.Conclusions. The study showed the high effectiveness of vaccination with Sputnik V against COVID-19 among the working population.
