RESUMO
AIMS: Because media portrayal reflects and shapes public opinion and health policy, investigating news coverage of public health issues is highly relevant for public health research and practice. Addressing a topical issue, this study investigated how newspaper coverage framed COVID-19 vaccines in Austria and German-speaking Switzerland and how it developed over time. METHODS: A quantitative newspaper content analysis of six newspapers from Austria and German-speaking Switzerland published between January 1 and 31, 2022 was conducted. Frames were identified for each country separately through hierarchical cluster analysis (Ward's method) based on frame elements. RESULTS: Four frames were identified in both countries: (1) Evaluating new vaccines, (2) Discussing mandates, (3) Promoting vaccination, (4) Mentioning vaccines. In Frames 1 (Switzerland 86.4%, Austria 93.3%) and 3 (Switzerland 92.7%, Austria 98.9%), most articles included vaccine-endorsing statements, with Swiss coverage including additional negative statements more often than Austrian coverage (43.2%/44.6% vs 4.0%/3.3%). Frame 2 was closely linked to vaccine skepticism only in Austria and contained more evaluative statements in Austrian newspapers (25.4% endorsing, 35.4% rejecting; in Switzerland 14.5%/18.1%). The Austrian tabloid Kronen Zeitung published most articles (497/1091, 45.6%). CONCLUSIONS: The commercialized and comparatively high share of tabloid news coverage in Austria may have contributed to oversimplified and polarizing COVID-19 vaccine debates in this context. Insufficiently balanced and adequate information may contribute to a loss of public trust in vaccination and may therefore affect vaccination uptake. Authorities and public health professionals should consider this effect when designing information campaigns.
