New Report Reveals Disparities in Adult Vaccine Access and Uptake Across Global Cities

A new report from the IQVIA Institute for Human Data Science, funded by GSK in collaboration with the Global Coalition on Aging (GCOA), sheds light on the role of social and structural determinants of health in adult vaccine access and uptake across five global cities. The study, examining data from Bangkok, Brussels, Chicago, Manchester, and New York City, reveals significant disparities in vaccine utilization even within single cities, emphasizing the need for policy interventions at the local and national levels.

Key findings from the report indicate that improved access to pharmacies and vaccination points positively correlates with higher vaccine uptake in Brussels and Manchester. In Bangkok, the number of vaccination points and economic growth indicators in a district influence adult vaccine use. In contrast, household income, education, median house value, race, and ethnicity significantly affect vaccination rates in New York City and Chicago, with Caucasian populations showing higher vaccine uptake.

Significant Disparities in Adult Vaccine Access Revealed in Urban Areas

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. 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. Adult vaccine use varies substantially across district groups, potentially driven by the presence of hospitals and clinics.

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). 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).

These findings underscore the importance of tailored policies to ensure equitable access to adult immunization. The report also highlights the need for comprehensive data analysis at the community level to drive informed policy decisions, enhance funding, improve access, and bolster education on adult vaccines.

Addressing Global Health Disparities and the Role of Stakeholders

Piyali Mukherjee, Vice President and Head of Global Medical Affairs, Vaccines, GSK, stressed the significance of prioritizing adult immunization, given the increasing elderly population worldwide. Mukherjee emphasized that adult vaccination can play a crucial role in preventing vaccine-preventable diseases, reducing healthcare system costs, and ensuring the well-being of communities. The data presented during the annual Silver Economy Forum, hosted by GCOA and partly sponsored by GSK, aim to facilitate discussions among global leaders, policymakers, and industry experts on solutions to address vaccination inequities.

By leveraging city-level data, stakeholders can tailor interventions to meet the diverse needs of different communities and contribute to global initiatives such as the UN Decade of Healthy Ageing and the WHO Global Network for Age-Friendly Cities and Communities. Earlier this year, GSK launched the COiMMUNITY Initiative to reduce health inequities and boost adult immunization rates in the US through funding and resource sharing.
