Financing And Funding Gap For 16 Vaccines Across 94 Low- And Middle-Income Countries, 2011-30.

We estimated immunization program costs, financing, and funding gaps for sixteen vaccines among ninety-four low- and middle-income countries during the period 2011-30. Inputs were obtained from the Institute for Health Metrics and Evaluation, the 2020 Decade of Vaccine Economics costing analysis, the World Health Organization, Gavi, and the United Nations Children's Fund. We found a total funding gap of $38.4 billion between 2011 and 2030, with the cost of immunization delivery being the main driver (86 percent) of the funding gap. On average, government financing of vaccination programs steadily rises throughout the period. However, the decline in both Gavi and development assistance for health (DAH) financing anticipated between 2011 and 2030 outpaces the forecasted increases in domestic government immunization spending. Probabilistic sensitivity analysis was applied to both the costing and the scenario analyses to address uncertainty in the financing of vaccines and vaccine delivery. The results highlight a narrowing gap for vaccine acquisition but a growing gap for vaccine delivery, which emphasizes the critical need for resource mobilization and sustainable financial strategies for immunization programs at national and global levels, as well as a need to address the COVID-19 pandemic's potential effects on government financing for vaccines between 2021 and 2030.

COVAX and equitable access to COVID-19 vaccines.

Objective: To evaluate equity in the allocation and distribution of vaccines for coronavirus disease 2019 (COVID-19) to countries and territories participating in the COVID-19 Vaccines Global Access (COVAX) Facility. Methods: We used publicly available data on the numbers of COVAX vaccine doses allocated and distributed to 88 countries and territories qualifying for COVAX-sponsored vaccine doses and 60 countries self-financing their vaccine doses facilitated by COVAX. We conducted a benefit-incident analysis to examine the allocation and distribution of vaccines based on countries' gross domestic product (GDP) per capita. We plotted cumulative country-level per capita allocation and distribution of COVID-19 vaccines from COVAX against the ranked per capita GDP of the countries and territories to generate a measure of the equity of COVAX benefits. Findings: By 23 January 2022 the COVAX Facility had allocated a total of 1 678 517 990 COVID-19 vaccine doses, of which 1 028 291 430 (61%) doses were distributed to 148 countries and territories. Taking account of COVAX subsidies, we found that countries and territories with low per capita GDP benefited more than higher-income countries in the numbers of vaccines. The benefits increased further when the analysis was adjusted by population age group (aged 65 years and older). Conclusion: The COVAX Facility is helping to balance global inequities in the allocation and distribution of COVID-19 vaccines. However, COVAX alone has not been enough to reverse the inequality of total COVID-19 vaccine distribution. Future studies could examine the equity of all COVID-19 vaccine allocation and distribution beyond the COVAX-facilitated vaccines.
