Regional Disparities in Covid-19 Vaccine Distribution: A Global Analysis of Manufacturer Contributions and Product Availability

The unprecedented global effort to develop and distribute COVID-19 vaccines has highlighted remarkable scientific achievements and persistent inequities in access across populations. Analyzing of regional vaccine deployment patterns reveals critical insights into pandemic response dynamics, shaped by manufacturing capacity, regulatory frameworks, procurement strategies, and regional health priorities. Data from WHO regions (Africa, the Americas, Eastern Mediterranean, Europe, and Western Pacific) demonstrate significant disparities in vaccine types and suppliers, underscoring the complexity of global vaccination efforts. (Figure 1) illustrates this regional vaccine distribution by WHO regions.
