How reliable services and incentives increased immunization rates by six-fold

Every year, more than 25 million pregnant women and children lack access to basic immunization programs, with an estimated two to three million deaths resulting from diseases preventable through vaccination.¹ This intervention examined the change in immunization rates in response to a reliable supply of immunization services and incentives. The experimenters assigned villages into three groups: Group A villages were provided with monthly immunization camps; Group B villages were provided with similar camps but also small incentives in the form of raw lentils and metal plates; control group villages had to consult their government healthcare facilities for immunization. The results were very interesting; villages within Group B that were provided incentives had a 21% higher full-immunization record than the villages in Group A. Moreover, villages receiving a reliable supply of services within Group A and B had significantly higher immunization rates compared to the control group.
