<p>We selected ten districts in Oromia Region, Ethiopia, stratified by settlement type (urban/rural), MCV1 coverage (high ≥ 80%, low &lt;80% coverage), and history of measles outbreaks (measles outbreak between June 2019 and June 2020 or not). Barriers to MCV2 uptake were discussed using focus group discussions (FGDs), in-depth interviews (IDIs) with caregivers of children 12-24 and 25-36 months and key informant interviews (KIIs) with HCWs and community leaders. Participants were recruited through purposive sampling. Recorded data were transcribed, translated to English, and analyzed using ATLAS.ti v.09.</p>
