The problem
Intervention: Various health communication strategies aimed at reducing parental vaccine hesitancy, including media campaigns, government messaging, community-based engagement, and phone-based messaging.
Who it was tested with: Parents, carers, or primary caregivers of children aged 0-3 years in Nigeria.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"N = 12 studies met the inclusion criteria, and the relevant data were synthesized and analyzed using a thematic synthesis approach." This indicates a qualitative synthesis without comparison groups or outcome measurement, best classified as practitioner-level evidence with uncertain outcome direction.
The review synthesizes qualitative findings without quantifying effects on actual vaccination uptake, and does not report on study quality or risk of bias of the included studies.
