Initial intervention prototype

Intervention Component (Prototype)	Description of Intervention (Prototype)
Strengthen Communication	Data suggested that providing specific communication training would be beneficial for CHWs. Further data suggested that providing CHWs with training booklets would assist them with speaking to parent and child caregivers in less technical terms
Improve Coordination between CHWs and Senior CHWs	Data suggested that if senior CHWs were able to share select information with CHWs one week in advance of a vaccination campaign, this might encourage parent and child caregivers to accept vaccines. Data suggested it would be effective to share information in advance with parent and child caregivers on (1) the timing of vaccines; (2) which vaccines are available; (3) side effects; (4) how to anticipate and treat side effects with simple home treatments
Direct Vaccine Material for Parents	Providing information to caregivers in easy-to-read pamphlets was suggested to alleviate vaccine concerns
Involving Religious Leaders	As religious leaders are influential in this community, our data suggested that involving them in vaccination campaigns was essential to improving vaccine uptake
Policy Level Changes	Data suggested that many parent and child caregivers were unable to take their children for vaccines during the harvest season, as this was associated with loss of income. Further, the Pentavalent vaccine was specifically associated with parent and child caregiver frustration, as this led to many side effects and was a high contributor to hesitancy. Making policy recommendations and changes was one way to alleviate these issues
COVID-19 Communication Campaign	As the community did not perceive COVID-19 to be an issue at the time of primary data collection, data suggested that vaccine uptake would be difficult and slow unless communication about the COVID-19 vaccine began early
