A Snapshot of Different Types of Under Research Vaccines Against COVID-19: A Review

SARS-CoV-2 as an emerging coronavirus, which first emerged in late 2019 in China causes a respiratory disease called “Coronavirus Disease 2019 (COVID-19)’’. SARS-CoV-2 has since infected more than 26 million people worldwide and caused more than 864000 deaths as of September 04, 2020. The SARS-CoV-2 spike (S) protein consists of two subunits: S1 and S2, which plays a role in binding to cellular receptors and mediating the fusion process between the membranes of the virus and host cells. The S protein has an important role to induce neutralizing-antibody, as well as protective immunity, during SARS-CoV-2 infection. In this review, we focused on different types of the vaccine against COVID-19. *Corresponding Author: Maryam Fazeli; Email: m.fazeli@umsha.ac.ir Please cite this article as: Zandi M, Rashid S, Nasimzade S, Pourhossein B, Fazeli M.
