The Covid-19 epidemic continues today as a pandemic that affects all societies. Thousands of people have died from the virus in question. With the cooperation of national and international organizations, a struggle is being made to get rid of this pandemic. As part of the struggle, tests are carried out to detect infected people, while vaccination programs are applied to ensure permanent recovery. But deaths from Covid-19 are increasing inexorably. In this context, the number of tests applied, the number of vaccine doses administered, the number of cases encountered and the number of deaths from Covid-19 in the 7 most developed countries of the world were analyzed by panel data analysis method. Panel data analysis method is an econometric method that can analyze time series and cross-section data simultaneously. It was predicted that the vaccines administered could reduce deaths from Covid-19. It was estimated that if each dose of vaccine administered was increased, deaths from Covid-19 could decrease by 0.57 units. On the other hand, it was observed that the increase in the number of cases led to an increase in deaths from Covid19. The importance of the number of tests applied in the fight against Covid-19 was also determined. As a result, the importance of vaccination activities in the fight against Covid-19 has been scientifically demonstrated with the model obtained. On average, it is estimated that both vaccines can save a person's life.
