Summary: The study suggests that prioritizing at-risk individuals can reduce disease burden, with age being the most important factor for prioritization. Considering comorbidities can also improve the efficacy of vaccination campaigns in a resource-limited context. High vaccination coverage may be needed to completely relax control measures, and vaccination of children could help lower coverage targets.
