Abstract

COVID-19 has caused extensive human casualties with significant economic impacts around the globe, and has imposed new challenges on health systems worldwide. Over the past decade, SARS, Ebola, and Zika also led to significant concerns among the scientific community. Interestingly, the SARS and Zika epidemics ended before vaccine development; however, the scholarly com- munity and the pharmaceutical companies responded very quickly at that time. Similarly, when the genetic sequence of SARS- CoV-2 was revealed, global vaccine companies and scientists have stepped forward to develop a vaccine, triggering a race toward vaccine development that the whole world is relying on. Similarly, an effective and safe vaccine could play a pivotal role in eradi- cating COVID-19. However, few important questions regarding SARS-CoV-2 vaccine development are explored in this review.
