However, the emergence 50 of more transmissible SARS-CoV-2 variants may threaten the potential herd immunity sought from 51 mass vaccination campaigns. 52 The objective of this study was to provide an up-to-date comparative analysis of the characteristics, 53 adverse events, efficacy, effectiveness and impact of the variants of concern (Alpha, Beta, Gamma and 54 Delta) for fourteen currently authorized COVID-19 vaccines (BNT16b2, mRNA-1273, AZD1222, 55 Ad26.COV2.S, Sputnik V, NVX-CoV2373, Ad5-nCoV, CoronaVac, BBIBP-CorV, COVAXIN, 56 Wuhan Sinopharm vaccine, QazCovid-In, Abdala and ZF200) and two vaccines (CVnCoV and NVX- 57 CoV2373) currently in rolling review in several national drug agencies.
