Trends in Global Adult Vaccination: A View from Five Global Cities
Dec 03, 2023
This sub-city level research showcases that vaccine use varies substantially even within cities and that urban policies are important for ensuring equitable access to adult vaccines. Demographic factors that vary within cities can also impact vaccination coverage, and accounting for these factors will be important for achieving equity of vaccine use. Optimal use of adult vaccines can be potentially enhanced with a focus on tracking adult vaccination data regularly at national and sub-national levels, ensuring financial considerations do not impact vaccine uptake, increasing the number of vaccinators, ensuring that vaccine policies account for sub-city level differences in vaccine use, and providing the basis for a growing and robust market that has incentives for ongoing innovation.
Key findings:
Vaccine use in each Brussels city district by type
- Adult vaccine use per 10,000 adults varies across districts, with the highest district seeing nearly four times the vaccine use per 10,000 adults compared to the lowest vaccine using district.
- Highest volumes were recorded in Woluwe and Brussels Haut and lowest in St-Gilles and Forest, with influenza accounting for just over half of volumes.
Vaccine use in each Manchester city ward by type
- Adult vaccine use per 10,000 adults varies across wards with the highest ward seeing nearly seven times the vaccine use per 10,000 adults compared to the lowest vaccine using ward.
- Note: Wards in the United Kingdom are electoral districts at sub-national level represented by one or more councilors.
Vaccine use in each Bangkok city district by type
- Adult vaccine use varies substantially across district groups, potentially driven by the presence of hospitals and clinics.
- Adult vaccine use is concentrated in a few district groups likely due to the presence of vaccination points.
Vaccine use in each Chicago county by type
- Adult vaccine use per 10,000 inhabitants varies across counties in Chicago, with the highest county (Dupage) seeing nearly 70% more vaccine use per 10,000 inhabitants compared to the lowest vaccine using county (Kane).
- Household income, education, lack of insurance, and median house value are highly correlated with vaccination rates across all vaccines studied; race and ethnicity also show correlations with vaccination rates in some cases.
Vaccine use in each New York City borough by type
- Adult vaccine use per 10,000 inhabitants varies across boroughs in New York, with the highest borough (Manhattan) seeing over 1.5 times the vaccine use per 10,000 inhabitants compared to the lowest vaccine using borough (Bronx).
- Household income, education and median house value are highly correlated with vaccination rates across all vaccines studied; race and ethnicity also show correlations with vaccination rates in some cases.
