Economic and health consequence frames affect COVID-19 vaccine incentive attitudes in Germany- a survey based framing experiment.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSARS-CoV-2 vaccines have significantly reduced human and economic losses. Nevertheless, vaccine hesitancy remains a major issue in many countries, including Germany. Recent studies have shown that public health framing and incentives can boost immunization rates. However, available evidence is fragmented and inconclusive regarding the effectiveness of different framing messages, types of incentives, and the size of financial incentives across different populations.
methodsThis randomized, controlled survey experiment elicited the attitudes of 6,685 Germans towards 4 financial/non-financial SARS-CoV-2 immunization incentives (food voucher, football tickets, participation in lottery, immediate monetary compensation), and tested whether framing (individual/collective, health/economic consequences) affected said attitudes. We assigned participants to five study arms (control: no frame; experiment: 1 of 4 frames) and measured attitudes towards immunization incentives, and the amount of monetary compensation deemed appropriate, should such an incentive be considered.
resultsWhile > 75% of our sample considered all 4 incentives to be not meaningful, all frames increased favorable views towards the financial incentives lottery/money and the average amount deemed acceptable for immediate monetary compensation. Interaction models showed that all frames have similar effects across core subgroups, e.g. age-cohorts, gender, vaccine doses.
conclusionsAcross a sample of 6,685 Germans, we show that 4 different frames detailing the potential individual/collective consequences of COVID-19 have very similar effects on attitudes towards monetary incentives for SARS-CoV-2 immunization. Our results suggest that the existence of frames rather than specific narratives is key to increasing favorable views towards immunization incentives. CLINICAL TRIAL NUMBER: Not applicable.
