Since then, companies and research institutions have raced Accepted 13 December 2020 to develop SARS-CoV-2 vaccines, ranging from conventional viral and protein-based vaccines to those that are Available online 17 December 2020 more cutting edge, including DNA- and mRNA-based vaccines. Each vaccine exhibits a different potency and du- ration of efficacy, as determined by the antigen design, adjuvant molecules, vaccine delivery platforms, and im- munization method. In this review, we will introduce a few of the leading non-viral vaccines that are under clinical stage development and discuss delivery strategies to improve vaccine efficacy, duration of protection, safety, and mass vaccination. ©2020ElsevierB.V.Allrightsreserved.
