COVID-19 Vaccination Coverage - World Health Organization African Region, 2021-2023.

Area of Science:

• Public Health
• Epidemiology
• Vaccinology

Background:

• COVID-19 vaccines became available in early 2021, offering a key strategy against morbidity and mortality.
• The World Health Organization (WHO) initially aimed for 70% global vaccination by mid-2022.
• By July 2022, WHO shifted focus to prioritizing high-risk groups in the African Region for maximum impact.

Purpose of the Study:

• To assess COVID-19 vaccine delivery and administration in the African Region.
• To evaluate vaccination coverage among the general population and priority groups.
• To inform ongoing strategies for sustainable COVID-19 immunization programs.

Main Methods:

• Analysis of vaccine delivery and administration data in African countries up to December 31, 2023.
• Calculation of cumulative population coverage for at least one dose, primary series, and booster doses.
• Assessment of coverage rates specifically for older adults and healthcare workers.

Main Results:

• Approximately 860 million vaccine doses delivered, with 646 million administered in the African Region.
• 38% of the African population received at least one dose, 32% completed a primary series, and 21% received a booster.
• Primary series coverage was 52% for older adults and 48% for healthcare workers, with significant country-level variations.

Conclusions:

• Despite progress, COVID-19 vaccination coverage in the African Region remains below initial global targets.
• Current WHO recommendations emphasize continued vaccination of priority populations and integration into primary healthcare.
• Strengthening life-course immunization and pandemic preparedness are essential for long-term public health security.
