Registry systems play a key role in promoting vaccination campaigns in the general population. In the present narrative review, we provide data from 12 12 countries for vaccination acceptance before the availability of COVID-19 vaccines and vaccination coverage once it is available. We selected a randomized representative sample of 12 countries from WHO regions and 194 total members by the Open Epi Random Program. We observed the results with different levels of vaccine acceptability between the studies that were performed before the availability of a vaccine against COVID-19 and the vaccination coverage after the availability of the COVID-19 vaccine. All the registry systems that were developed for the recent pandemic achieved the initial functional goals. Twelve months after the vaccination campaign has begun, varying results were reported for vaccination coverage against COVID-19 vaccines with rates as high as 98% (subjects with at least one dose of vaccine) in the United Arabic Emirates, and as low as 24% in South Africa. The United Arabic Emirates stood as the leader of the world with the highest number of vaccinations 88% fully vaccinated citizens followed by Canada with 80% fully vaccinated citizens. The available data suggest that vaccine registry systems could help increase vaccination coverage and aim in the control of future outbreaks.
