description Introduction. The pandemic spread of a new coronavirus infection, COVID-19, has caused a global emergency and attracted the attention of public health professionals and the population of all countries. A significant increase in the number of new cases of SARS-CoV-2 infection demonstrates the urgency of finding drugs effective against this pathogen. The aim of this work was to evaluate the in vitro antiviral efficacy of human recombinant alpha-2b interferon (IFN-α2b) against SARS-CoV-2 virus. Material and methods. The experiments had been carried out on Vero Cl008, the continuous line of African green monkey (Chlorocebus sabaeus) kidney cells. The effectiveness of the drugs was assessed by the suppression of viral reproduction in vitro. The biological activity was determined using titration of a virus-containing suspension in a Vero Cl008 cell culture by the formation of negative colonies. Results. The antiviral efficacy of the IFN-α2b-based medications, which have a high safety profile and proven efficacy in the prevention and treatment of influenza and acute respiratory viral infections (ARVI), has been studied against the new pandemic SARS-CoV-2 virus in vitro experiments in Vero C1008 cell culture. IFN-α2b effectively inhibits the reproduction of the virus when applied both 24 hrs before and 2 hrs after infection. In the IFN-α2b concentration range 102–106 IU/ml a complete suppression of the reproduction of the SARS-CoV-2 virus had been demonstrated. Discussion. IFN-α2b demonstrated in vitro high antiviral activity against SARS-CoV-2. In addition, the substance has a high chemotherapeutic index (1000). Conclusion. Medications for intranasal use based on IFN-α2b have high antiviral activity and are promising drugs for in vivo study in terms of prevention and treatment of COVID-19.
