Closing the Immunization Gap

The gap between vaccines and the people they protect can be measured by the difficulty of overcoming the social, economic, physical, policy and behavioral barriers to reach professional, and empathetic immunization services.



Applying Behavioral Insights to Immunization

We seek to leverage socio-behavioral sciences to strengthen immunization programmes and build quality health services to increase demand for vaccines to protect all.

Demand Generation is a key component of overall strategies to engage communities and increase uptake of services, particularly among under-immunized groups.


Demand is evident when parents, caregivers, communities and other key in-country stakeholders value, trust, and actively seek immunization. Effective demand generation interventions use tailored, evidence-informed and data-driven strategies to maximize immunization uptake in the target population. Demand generation is a key component of overall strategies to engage communities and increase uptake of services, particularly among under-immunized groups.

However, research into behavioral sciences for immunization and leveraging them to create interventions to boost demand is still in its infancy and is being incubated at the Hub. Here, different skillsets—from behavioral science to epidemiology, design, communications and sociology, are being harnessed to develop and road test new ideas at the country level. We know one size does not fit all, and so, we seek demonstrated but flexible tools that can be used and repurposed for different populations, places and vaccines.
