Within the 2020/21 CICADA (Coronavirus Intersectionalities: Chronic Conditions or Disabilities and Migrants and other Ethnic minorities) study, we explored full, partial or noncompliance with government COVID-19 infection-containment measures by people from minoritised ethnic groups with a disabling health condition or impairment. We used an assets-based intersectional approach and purposive sampling, included non-disabled and White British comparators, and trained community co-researchers to help us reach undocumented migrants and asylum seekers. We undertook 271 semi-structured qualitative interviews, followed by participatory workshops with interviewees to explore data and changes in experiences five and 10 months after the interviews. Perceiving their vulnerability to COVID-19, most participants quickly and often zealously adopted infection-containment behaviours, and continued this after restrictions were lifted. This could reduce mental wellbeing, especially in community-facing cultures, and could create family conflict. Various structural inequities impeded compliance. Many, especially undocumented migrants, felt imprisoned. The intersection of gender, citizenship, socioeconomic status and culture impacted disclosures of COVID-19 infection, support seeking and use. Many were unclear what was safe as well as unsafe. People complained that disability and cultural considerations were omitted from policymaking. Participants mostly had taken the COVID-19 vaccine by October 2022, but ethnic minority participants needed time to deliberate and trusted, community-embedded information whereas White British participants were mostly influenced by mass media. The intersection of health condition or impairment, poverty, and living alone led to more non-compliance with general rules, and more vaccine hesitancy than did misinformation spread through ethnic community channels. Many participants were reluctant to reintegrate in May 2022 because of continued perceived vulnerability to COVID-19 but by September 2022 = seemed more concerned about the economic crisis. We add two new 'types' to existing compliance typologies: deliberators (who eventually decide to follow the rules), and 'necessity-driven non-compliers' who are totally unable to comply because of their disabilities.
