"If it wasn't forced upon me, I would have given it a second thought": Understanding COVID-19 vaccine hesitancy in an outlier county in the Bay Area, California.

While the San Francisco Bay Area counties rank very low in vaccine hesitancy and high in vaccination rates when compared to national numbers, Solano County has the most residents who are hesitant (6.3%) and the least who are fully vaccinated (51.6%) among Bay Area counties, according to the CDC. No studies to date have been able to provide the in-depth, localized information that would inform county-level public health interventions. This study aims to explore reasons and consequences for remaining unvaccinated in Solano County. Using a qualitative in-depth interview approach, we conducted 32 interviews with unvaccinated adults from Solano County. We used a grounded theory approach to our analysis. Using the socio-ecological model as a framework, we found that reasons for not getting vaccinated were primarily structural (mistrust of public information) and individual (bodily autonomy, personal choice) while consequences were primarily interpersonal (discrimination and stigma from friends, family, and employers). An overarching theme was that the vaccine rollout and messaging felt like an encroachment on personal choice and the feeling of being forced created more mistrust. Participants reported feeling like their decisions made them minorities among their colleagues, friends and family and that they were not persuaded by groupthink or by their relationships. Future public health responses to epidemics and pandemics might consider if a vaccine mandate is the best approach for reaching all county residents.
