**1. Introduction**

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a singlestranded positive sense ribonucleic acid (ssRNA) virus with an envelope that leads to coronavirus disease 2019 (COVID-19) [1]. COVID-19 has affected millions of people worldwide since its emergence in December 2019 in Wuhan in China. It has caused a worldwide pandemic. Multiple mutated variants of SARS-CoV-2 have appeared with varying infectivity [2, 3]. SARS-CoV-2 has caused major disease burden and death rates worldwide. Due to the threat to individual health and health systems, SARS-CoV-2 and COVID-19 have resulted in a worldwide social and economic crisis. Economically rich Western countries have success in fighting SARS-CoV-2 by vaccination, while this is not true to the same extent for economically weak countries due to a shortage of vaccine supply. In addition, the standard of care for patients with COVID-19 differs dramatically based on the economic wealth of a country [4]. Due to the nature of the pandemic to affect people worldwide, there is a lack of help from rich countries for economically weak countries.
