*This was based on the question “People in Canada come from many different ethnic and racial backgrounds. I would like you to identify which ethnicity best describes you. You may choose more than one category.” The ethnic groupings were based on the categories similar to Statistics Canada definitions.

For adults, all models were adjusted for age, sex, children in household, material deprivation, chronic conditions, receipt of 2008 seasonal vaccine, tested prior to June 11th, 2009, length of stay in Canada
