Geographic Inequity

Many vaccine-preventable diseases are inequitably distributed geographically. For example, children living in urban communities may be at increased or decreased risk of a given disease due to specific disease risk factors, access to primary health care services and treatment, etc. Geographic inequity may also refer to the geographic distribution of vaccines. Some distant or rural communities are harder to reach, both with preventive and treatment services. Geographic inequity may also overlap with factors associated with wealth inequity or educational inequity. For example, some rural populations may have lower wealth and educational attainment than an urban population in the same region.

Key Idea

Polio eradication investments in health infrastructure have been concentrated in some of the lowest performing health systems in the world, challenged internally by geography, poverty, armed conflict, etc. These assets can be leveraged to improve the health system and immunization overall nationally.

Key Idea

Children in slum settings have higher burdens of vaccine-preventable disease (one study found children in slums in Manila, Philippines were 9 times more likely to have tuberculosis than other urban children) and lower rates of immunization (a study in Niger found 35% coverage in slums vs. 86% in non-slum urban areas).

Key Idea

Inequity in vaccination coverage in India was found between states, within states, in urban vs. rural. Lower parental education resulted in lower coverage, girls had lower coverage than boys and infants born to families with a large number of children also had lower coverage than others. A direct relationship between household wealth and coverage was also found.
