What is already known on this topic: Inequalities in childhood vaccination uptake in England are stark and have widened, especially for MMR vaccination.Child poverty in England has increased and is associated with rising inequalities in multiple domains of children's health but impacts on inequalities in vaccination uptake are unclear.What this study adds: A 1 percentage-point increase in child poverty was associated with a 0.17 percentage point fall in uptake of MMR1 and a 0.26 percentage point fall in MMR2 between 2015 and 2024.Reducing child poverty is likely to increase vaccine uptake and reduce the burden of vaccine preventable diseases in England.
