Message effectiveness by trust cue versus no trust cue and inclusion of scientific evidence supporting vaccines versus no evidence.
Bar graph illustrating the mean perceived message effectiveness (PME) score (2a) and mean pro-vaccine belief score (2b) for participants in each condition, with 95% confidence intervals. PME was measured using a six-item scale ranging from 1–6. Pro-vaccine belief was measured using a five-item scale ranging from 1–7.
