Inequalities in adolescent HPV, Td/IPV and MenACWY vaccination coverage by socio-economic status: an ecological study, England, 2017 to 2024.

BACKGROUNDMany countries use school-based vaccination for adolescent vaccination; it has been shown to reduce inequities in uptake compared with other delivery routes. In England, coverage for human papillomavirus (HPV), meningococcal groups A, C, W and Y (MenACWY) and tetanus, diphtheria and inactivated polio virus (Td/IPV) vaccine programmes exceeded 80% before the COVID-19 pandemic. However, recent data show declining uptake.AIMThis study examined the relationship between socio-economic deprivation and coverage over time.METHODSWe conducted an ecological analysis of first-dose coverage for HPV (females and males), MenACWY and TdIPV in adolescents across 150 local authorities in England from 2017 to 2024. Coverage data were linked to 2025 Index of Multiple Deprivation (IMD) scores. Associations between IMD quintile, academic year and vaccination coverage were estimated using beta regression models.RESULTSBetween 2020 and 2024, lower coverage was consistently associated with higher deprivation, and differences in coverage between the most and least deprived IMD quintiles more than doubled. In 2024 these differences were 17.7%, 18.2%, 16∙8% and 16.9% for HPV (females), HPV (males), MenACWY and Td/IPV, respectively. The consistency of these findings suggests the effect of deprivation on coverage is not vaccine-specific.CONCLUSIONWe demonstrated a consistent and strengthening association between coverage and deprivation across multiple adolescent school-based vaccination programmes in England over time. Contributory factors may be numerous, and further research is needed to understand which factors are driving trends for different populations. Addressing these inequalities will require sustained targeted interventions to improve awareness of and access to vaccination.
