摘要：<p><strong>Introduction.</strong> Due to the still difficult and worsening epidemic situation in Poland, related to the second wave of the coronavirus pandemic (COVID-19), it turned out to be necessary to develop, prepare and conduct additional training on the work of medical personnel during the pandemic. Preventive vaccinations and their skilful implementation play a very important role.</p><p><strong>Aim.</strong> The aim of the systematic review is to present the general principles, procedures and competences of nurses in the pandemic era, this work can be used to conduct a comparative meta-analysis.</p><p><strong>Disscusion.</strong> The vaccine protects against the symptoms of COVID-19, which has been proven in clinical trials. For both the Comirnaty vaccine and the Moderna vaccine, the European Medicines Agency website states that the effect of vaccination on the transmission of the virus is unknown and whether vaccinated people can transmit SARS-CoV-2. Clinical trials are scheduled for 2 years and, as part of conditional approval, companies will complete the data after subsequent periodic evaluations.</p><p><strong>Conclusion.</strong> Over 1.5 million people worldwide have died since the outbreak of the COVID-19 epidemic. Each vaccinated person is potentially from a few to a dozen or so people protected against infection. Already 50% of the vaccinated population will significantly reduce the risk of spreading the coronavirus in it. Vaccines are the most effective method of protection against infection with various diseases. Humanity has been successfully using this achievement of civilization for several hundred years.</p>
