# Public and donor investment in immunization systems

Public and donor investment in immunization systems refers to resources—from national health budgets, multilateral bodies, and donors such as Gavi—directed at procuring vaccines and maintaining the systems that deliver them, including cold chains, logistics, health workers, and surveillance.

The mechanism operates by lowering the cost and increasing the availability of vaccination services, which can raise immunization coverage and, in turn, is associated with reductions in vaccine-preventable disease; these links are well supported but mediated by health-system capacity, demand, and equity. Temporal dynamics are mixed: building delivery infrastructure takes years, while coverage effects can shift more quickly, and funding is vulnerable to budget cycles. Scope ranges from global financing initiatives to national and subnational programs. Uncertainty arises because outcomes depend on many co-factors, making attribution to investment alone difficult. This driver primarily affects indicators of immunization coverage, child mortality, and the incidence of vaccine-preventable diseases.
