Abstract
Today, the fight against COVID-19 is the most important agenda topic of all countries. Countries are trying to combat COVID-19 by implementing policies consisting of quarantine, testing and vaccination practices and medical treatment service. Considering the current test and vaccine production capacity with the world population, the effective use of these resources is of great importance in terms of combating the pandemic. For this reason, the relative efficiency of 41 OECD and EU member countries in the fight against the pandemic is analyzed with the help of Data Envelopment Analysis. According to the results of the analysis; Only 8 of 41 countries have relative technical effectiveness in combating the pandemic. The country with the lowest relative technical efficiency value is Chile, while the country with relatively low technical efficiency but closest to the efficiency limit is Ireland. It is seen that countries that are among the developed and richest countries such as the USA and Canada are among the countries with the worst performance in the fight against the pandemic. Turkey, on the other hand, is among the countries that can not achieve technical efficiency.
