WHO SAGE Roadmap Priority-Use Groups for COVID-19 Vaccine
This revised Roadmap takes into account increasing vaccine availability, vaccine coverage rates, and the evolving epidemiological situation including COVID-19 variants of concern.
To assist countries in developing recommendations for optimized use of vaccines against COVID-19, priority-use groups for vaccination (both primary series and booster doses) are identified based on epidemiological scenarios, public health goals, and vaccine coverage scenarios.
High priority is: Elderly, health workers, immunocompromised. The next tier down, high priority, is adults with co-morbidities, pregnant persons, teachers and other essential workers, disadvantaged socioeconomic subpopulations at higher risk (could be migrants, etc).
