Between March 19, 2021 and April 1, 2021, CHRT fielded a representative survey of Michigan adults to better understand who isn’t getting vaccinated against COVID-19 and the reasons why. Latinx/Hispanic, adults with lower incomes, respondents without health insurance, and respondents without a medical home were all less likely to have received at least one dose of the COVID-19 vaccine compared to counterparts. Most of those who did not intend to get vaccinated were worried about side effects (86%). This was followed by concerns that the vaccine was too new (83%) and a mistrust of government to ensure the safety of the vaccine (78%). Other reasons included a belief that the effects of COVID-19 have been exaggerated or that respondents were not at risk for infection.
