The COVID-19 pandemic has revealed significant disparities in global vaccine accessibility, particularly affecting low and middle-income countries (LMICs). However, current research on accessibility primarily focuses individual or high-income (HIC). We aimed to evaluate geographic vaccination a multicountry scale, covering comparisons across LMICs HICs. Additionally, we explored the potential economic factors related their impacts health outcomes. collected population data at 1 km resolution geocoded all sites selected countries/regions. Four measures were used from different perspectives: coverage with varying travel time thresholds, driving sites, number of within 30-min threshold index using enhanced two-step floating catchment area method. Finally, relationships between several factors: gross domestic product per capita, uptake mortality. found substantial In 24.07% these countries/regions, over 95% can access nearest services 15 min. contrast, countries/regions such as Manitoba (Canada), Zimbabwe Bhutan, less than 30% reach 60 Underserved areas, termed 'vaccine deserts', identified both HICs LMICs. that higher tend achieve rates, whereas those lower are likely experience increases mortality rates. require attention improve vaccination. there internal National public officials initiatives suggested prioritize deserts' ensure equitable future pandemics.
