A study published in The Lancet examined the connection between the number of health workers in developing countries and vaccinations. Findings revealed that “a higher density of health workers (nurses) increases the availability of vaccination services over time and space, making it more likely that children will be vaccinated.” 

Apart from the obvious health benefits, studies have explored the additional societal benefits of vaccinations in developing countries. Vaccination programs have introduced healthcare services as well as educational opportunities for mothers. Immunization in developing countries has led to the outcome of smaller families, and a higher standard of living. Women, as the principle caregiver, benefit by making choices to limit family size and space births (allowing for enough resting time between pregnancies). By becoming more educated and empowered, women in developing countries take more control of their own health as well as that of their children.
