Children who remain in school longer and achieve higher educational outcomes generally earn better wages and have improved employment prospects as adults. Researchers have begun to explore whether similar long-term benefits extend to those who receive childhood vaccinations. Evidence from Burkina Faso suggests they do. By analyzing differences in vaccination coverage across regions and birth cohorts, studies found that early-life immunisation was linked to higher school enrolment and completion decades later. In regions with higher vaccination rates, school enrolment increased by around 10%, while primary school completion rose by approximately 13%.
The benefits of vaccination also appear in the labor market. Individuals from highly vaccinated areas were about 7% more likely to secure formal, wage-paying jobs, which offer greater security and protection. The advantages extended beyond formal employment: in largely agricultural economies, vaccinated individuals produced around 6% more per hectare than their peers. This increase was not due to greater inputs like land or fertilizer but likely reflected more efficient labor, as healthier individuals can make better use of the same resources over their lifetime.
The connection between vaccination and adult outcomes, however, is influenced by other factors. Gender norms, education systems, and job availability can affect whether gains in schooling translate into higher earnings. Even so, research shows that improvements in cognitive ability—often boosted by early immunisation—are strongly associated with better educational achievement and a subsequent increase in wages. A one standard deviation increase in cognitive ability can raise earnings by around 5%, illustrating the indirect but meaningful economic impact of vaccination.
The educational benefits of vaccination are often greatest for children from the poorest households, who face the highest burden of infectious diseases. In Bangladesh, for instance, maternal tetanus vaccination primarily improved schooling outcomes for children from lower socioeconomic groups. Poorer children are more likely to experience repeated infections, undernutrition, and limited access to healthcare, all of which can hinder physical growth and cognitive development. Preventing even a single serious illness during this critical developmental period can have long-lasting effects.
Vaccination can also help reduce social inequities. In areas where school enrollment is not universal, healthier children are more likely to attend school regularly, while those who fall sick often lag behind or drop out. Conversely, lack of vaccine access can deepen existing disadvantages, as children most at risk of missing vaccines are also likely to face barriers to education, economic mobility, and family stability. By protecting children, vaccines act as a potential equalizer, narrowing educational and opportunity gaps between wealthier and poorer populations. Declining vaccine uptake in high-income countries shows similar patterns, where disadvantaged communities are hit hardest by outbreaks.
For policymakers, these findings highlight that vaccination extends far beyond preventing illness. Immunisation shapes human capital by protecting children during critical periods, influencing learning, productivity, and future earnings. Despite often being framed as a health cost, vaccination offers substantial returns that reach into education, labor markets, and the broader economy. Communicating these long-term benefits is essential, especially as vaccine-preventable diseases become less visible. Emphasizing the connection between immunisation and a child’s future prospects can strengthen public support and investment in vaccination programs.
Even though many benefits unfold slowly and are difficult to measure, their impact over a lifetime is profound. Childhood vaccinations do more than save lives—they create the conditions for children to thrive academically, economically, and socially, underlining the critical role of immunisation in building healthier, more equitable societies.
