Figure 2. — Vaccine efficacy against symptomatic coronavirus disease 2019 (COVID-19), from Phase 3 clinical trials. Each efficacy value is for the complete vaccine course (1 dose for Ad26.COV2.S/Janssen and Ad5-nCoV/CanSinoBio, 3 doses for BioCubaFarma/Abdala and Soberana02+/BioCubaFarma, and 2 doses for all others).
