COVID-19 vaccination plans in Latin America and the Caribbean: a multi-country comparative analysis of prioritization strategies.

ABSTRACT

OBJECTIVES: This study aimed to synthesize and compare the prioritization strategies outlined in the national vaccination plans (NVPs) against Coronavirus Disease 2019 (COVID-19) developed by countries in the Latin America and Caribbean (LAC) region. STUDY DESIGN: We conducted a comparative policy analysis based on COVID-19 NVPs. METHODS: We conducted a search strategy in three stages to identify NVPs for COVID-19 across 41 countries/territories in the LAC region. Sources included official governmental repositories, complementary Google searches, and less formal documentation. We extracted key variables and conducted a comparative policy analysis based on the prioritization criteria and specific prioritization groups. RESULTS: The study identified 52 NVPs for COVID-19, corresponding to 27 (65.8 %) out of 41 countries/territories in the LAC region. Official national websites yielded documents for 12 countries. All NVPs included frontline healthcare personnel in the first prioritization phase/stage, whilst some included residents of long-term healthcare facilities, adults aged 60 years or more, and people with disabilities. The decision criteria for prioritization were declared in 14 countries/territories. Ethical considerations declared in five NVPs included human welfare, equality, solidarity, equity, and social justice as values. CONCLUSION: The early stages of vaccination rollout in LAC countries prioritized protection of the healthcare system and epidemiological risk for severe disease. Few countries included ethical considerations in their NVPs, and global inequities in vaccine access and distribution led to varied protections for vulnerable populations across LAC. This analysis highlights the need for improved emergency-response capacity, planning, and enhanced multilateral cooperation in the LAC region for future public health emergencies.
