Effectiveness of COVID-19 Vaccines Against Delta Variant: The Case of the Maldives.

This article focuses on assessing the impact of COVID-19 vaccines on the Delta variant in the Maldives using retrospective analysis of case data from March 2020 to December 2021. The study found that a single vaccine dose was insufficient to prevent a surge in Delta variant cases, which occurred about three months after initial widespread vaccination; however, the administration of second doses combined with reinstated preventive measures led to a gradual decline in infections. The findings emphasize the importance of completing the full vaccination regimen, as recommended by the World Health Organization (WHO), alongside non-pharmaceutical interventions to effectively control highly transmissible variants like Delta. The study also highlights equitable vaccine distribution across the Maldivian population and supports flexible vaccination policies, including booster doses, to manage ongoing COVID-19 challenges.
