Abstract
AIMS: We studied time trends in seasonal influenza vaccination and assessed associations with socioeconomic and health-related determinants in Switzerland (overall and people aged ≥65 years). METHODS: We used data from the Swiss Health Surveys of 2007 and 2012. We calculated the proportion of the population (overall and those ≥65 years old) reporting influenza vaccination in the last 12 months, and performed multivariate logistic regression analyses, presented as adjusted odds ratios (aORs). RESULTS: The average overall frequency of people reporting having been vaccinated for influenza in the previous 12 months was 15.2% (95% confidence interval [CI] 14.7–15.7); frequency decreased from 16.4% in 2007 to 14.1% in 2012 (p <0.001). In elderly people (≥65 years) the frequency declined from 47.8 to 38.5% (p <0.001). The decline was more pronounced in both the 15 to 19 age group (aOR 0.5, 95% CI 0.3–1.0) and those 65 to 75 years old (aOR 0.6, 95% CI 0.5–0.7), and in those with less education (aOR 0.6, 95% CI 0.4–0.7). Pregnant women had the lowest frequency for influenza vaccination (2.3%, 95% CI 0.6–7.9), but the frequency increased between 2007 and 2012 (aOR 4.5, 95% CI 1.0–20.5). Influenza vaccination in the last 12 months was positively associated with the ≥65 age group, living in French-speaking and urban areas, history of smoking, bad self-reported health status, health insurance for private/semiprivate hospital stays and working in healthcare professions. CONCLUSIONS: Influenza vaccination coverage was low overall and declined over time. To increase influenza vaccine uptake and reach the European target of 75% in people aged ≥65 years, more efforts should be put into novel intervention approaches.
