Science-driven storytelling and entertainment-education (E-E) media demonstrate potential for promoting improved attitudes and behavioral intent towards health-related practices. Months after the outbreak of coronavirus disease 2019 (COVID-19), emerging research highlights the essential role of interventions to improve public confidence in the COVID-19 vaccine. To improve vaccine confidence, we designed three short, animated videos employing three research-informed pedagogical strategies. These can be distributed globally through social media platforms, because of their wordless and culturally accessible design. However, the effectiveness of short, animated storytelling videos, deploying various pedagogic strategies, needs to be explored across different global regions.
METHODS/DESIGN: The present study is a multi-site, parallel group, randomized controlled trial (RCT) comparing the effectiveness of (i) a storytelling-instructional-humor approach, (ii) a storytelling-analogy approach, (iii) a storytelling-emotion-focused approach, and (iv) no video. For our primary outcomes, we will measure vaccine hesitancy, and for secondary outcomes, we will measure behavioral intent to seek vaccination and hope. Using online platforms, we will recruit 12,000 participants (aged 18-59 years) from the USA and China, respectively, yielding a total sample size of 24,000.
This trial uses innovative online technology, reliable randomization algorithms, validated survey instruments, and list experiments to establish the effectiveness of three short, animated videos employing various research-informed pedagogical strategies. Results will be used to scientifically support the broader distribution of these short, animated video as well as informing the design of future videos for rapid, global public health communication.

以科学为驱动的叙事和教育娱乐（E-E）媒体展示了促进改善与健康相关实践的态度和行为意向的潜力。在 2019 年冠状病毒病（COVID-19）爆发数月后，新出现的研究强调了干预措施对于提高公众对 COVID-19 疫苗信心的重要作用。为了提高疫苗信心，我们设计了三个简短的动画视频，采用了三种经过研究证明的教学策略。由于其无文字且具有文化可及性的设计，这些视频可以通过社交媒体平台在全球范围内传播。然而，需要在不同的全球地区探索使用各种教学策略的简短动画叙事视频的有效性。
方法/设计：本研究是一项多地点、平行组、随机对照试验（RCT），比较以下方法的有效性：（i）故事叙述-教学-幽默方法，（ii）故事叙述-类比方法，（iii）故事叙述-情感焦点方法，以及（iv）无视频。对于我们的主要结果，我们将衡量疫苗犹豫程度，对于次要结果，我们将衡量寻求接种疫苗和希望的行为意向。我们将分别使用在线平台从美国和中国招募 12000 名年龄在 18-59 岁的参与者，总计样本量为 24000 名。
该试验使用创新的在线技术、可靠的随机化算法、经过验证的调查工具和列表实验，来确定使用各种经过研究证明的教学策略的三个简短动画视频的有效性。结果将用于科学地支持这些简短动画视频的更广泛传播，并为快速、全球公共卫生传播提供未来视频的设计提供信息。
