In a pre-registered lab-in-the-field intervention study, participants were recruited in a public park (tested: $$n = 232$$, analyzed: $$n = 222$$). They were randomly assigned to experience the collective benefit of community immunity in a gamified immersive virtual reality environment ($$\frac{2}{3}$$of sample), or to receive the same information via text and images ($$\frac{1}{3}$$of sample). Before and after the intervention, participants indicated their intention to take up a hypothetical vaccine for a new COVID-19 strain (0–100 scale) and belief in vaccination as a collective responsibility (1–7 scale). The study employs a crossover design (participants later received a second treatment), but the primary outcome is the effect of the first treatment on vaccination intention. After the VR treatment, for participants with less-than-maximal vaccination intention, intention increases by 9.3 points (95% CI: 7.0 to $$11.5,\, p < 0.001$$). The text-and-image treatment raises vaccination intention by 3.3 points (difference in effects: 5.8, 95% CI: 2.0 to $$9.5,\, p = 0.003$$). The VR treatment also increases collective responsibility by 0.82 points (95% CI: 0.37 to $$1.27,\, p < 0.001$$). The results suggest that VR interventions are an effective tool for boosting vaccination intention, and that they can be applied “in the wild”—providing a complementary method for vaccine advocacy.",
