Global Study Reveals COVID-19 Vaccination Gaps for Older Adults

This study examines COVID-19 vaccination efforts for older adults globally. It highlights significant gaps in access and inconsistency in vaccination schedules.

The World Health Organization (WHO) ended the public health emergency status for COVID-19 in May 2023. Vaccination has been key in reducing virus spread and preventing severe illness. Updated booster doses help protect against varying virus strains, especially among high-risk groups. Vaccine equity aims to provide effective vaccines to eligible individuals, not just any available option.

The study analyzed data from public sources, looking at vaccine types, regimens, age groups, and coverage in various countries. The latest data was from July 10, 2024. Sources included government reports and media, with a focus on immunization success for older adults.

From 192 countries, 71 vaccines were given to older adults. Ninety countries used vaccines targeting variants of concern, while many original strain vaccines are now discontinued. Some regions offered additional booster doses, with 33 countries providing seasonal boosters.

Overall, 81% of older adults completed their primary vaccination series, but this varied widely by region. In the Western Pacific, completion was 91%, while in Africa, it dropped to 47%. The need for robust vaccination monitoring systems is crucial for informing policies and promoting campaigns.

To meet WHO goals, countries need 1.01 doses for primary coverage and 1.43 for booster coverage among older adults. Coverage varies by region. Effective vaccination programs require significant resources, even with donated vaccines. Periodic assessments of these programs help determine their value.

In summary, COVID-19 vaccination coverage is uneven worldwide. There is a pressing need for improved access and updated strategies to ensure older adults are adequately protected.
