The HAPPI Kenya project is undertaking a study on the uptake of HPV vaccines (HPVV) in two counties of Rift valley region. Study title: This study is an exploration of social and gender norms related to the uptake of HPV vaccines (HPVV) in two counties of Rift valley region, Kenya: Nandi County and Elgeyo Marakwet County. Background: To better understand and address low HPVV uptake in the two HAPPI Kenya project areas, there is an urgent need to understand the social norms that hinder girls’ vaccination. As such, we are using the methodology recommended in the Social Norms Exploration Tool (SNET) to conduct a rapid assessment. In Phase 1 of the SNET process, study team members with working experience in Nandi and Elgeyo Marakwet worked together to define the behaviors and populations of interest: Male and female caregivers proactively seeking HPVV for their daughters, and eligible girls (ages 10-14) proactively seeking HPVV. Next the team conducted a preliminary brainstorm to identify norms that likely pose barriers to those behaviors and target groups. Examples of those norms include descriptive norms such as “People in my community do not usually seek out information about health issues,” and injunctive norms such as “I am expected to follow the advice of religious leaders without questioning them.” Finally, in Phase 1, the study team identified the most likely community influencers, or groups likely to be cited by girls ages 10-14 and their male and female caregivers as having influence on their decision-making and behaviors. The study team is looking to engage four research assistant consultants to support the data collection process.
