The proportion of total doses distributed by region. Assuming that the total vaccine supply is 20% of the entire population, we explored various distribution strategies. The proportion of doses per region is shown based on each prioritization scheme: (A) doses are distributed to regions based on population size (pro-rata), (B) doses are allocated based on the distribution of people aged over 60 years between the regions (age), (C) doses are distributed to regions based on the number of cases reported (cases), (D) doses are distributed to regions based on the number of deaths reported (deaths)
