Individuals with mental illness are at high-risk for influenza (flu) and reduced receipt of preventive services i.e., flu vaccination. Yet, literature is limited on flu vaccination among this population. This study identifies flu vaccine rates and explores factors associated with having a flu vaccine among adults with mood/anxiety disorders living in 4 Canadian provinces. Data from the 2017-2018 Canadian Community Health Survey were analyzed. Of the mental illness sample, 65.1% received a flu vaccine in their lifetime. Of those, 55.9% received it less than 1 year ago. Those more likely to receive a lifetime flu vaccine are 60 years +, females, have higher education and household incomes, chronic comorbidities, non-smokers, non-sedentary behaviours, had relationships, primary care access, and lived in Alberta health regions. Findings highlight that Canadians with mental illness may need support to receive annual flu vaccines, and health interventions should target these specific factors to promote flu vaccination.
