Abstract: Vaccination is becoming one of the most important epidemic control measures in the post-pandemic era, and the pandemic has accelerated the development of various forms of COVID-19 vaccines. The inhaled vaccine has entered clinical trials as a more convenient form of vaccination. However, the nebulization equipment used in the experiments was not specifically designed for the public health care scenario of inhaled vaccine nebulization. It could not reflect the advantages and characteristics of the inhaled vaccine. This study is based on the scenario-based design theory to design practical application solutions for inhaled vaccine nebulization equipment. Methods: Using a scenario simulation experiment and semi-structured interviews we identified the behavioral requirements of medical staff in the inhaled vaccination scenario and invited expert participants to validate. Results: Based on interview analysis, 20 behavioral requirements and an inhaled vaccine medical staff persona were identified. Five optimized scenarios were designed according to scenario-based design theory. Scenarios were evaluated by expert participants, and the prototype was developed based on feedback. The prototype design concept focused on "optimizing human-machine interaction", "improving disposable inhaler design", and "optimizing vaccine reagent dosing process". Conclusion: The prototype was evaluated by experts to be effective and reasonable for practical application scenarios of the inhaled vaccine. Scenario-based design can be a useful tool for innovative product design in public medical service scenarios.
