- BA 30-year-old with a seasonal allergy一位患有季節性過敏的30歲人士

流感疫苗（Influenza vaccine）的接種優先順序旨在保護高風險族群。高風險族群包括免疫功能低下、慢性心肺疾病、糖尿病、孕婦及65歲以上長者。心衰竭（Heart failure）病患若感染流感，極易引發心肺功能失代償，進而導致嚴重併發症甚至死亡，因此在臨床護理邏輯中，優先保護心血管功能受損的個案是降低死亡率的核心策略。
The priority order of influenza vaccination is intended to protect high-risk populations. High-risk groups include the immunocompromised, persons with chronic cardiopulmonary disease, those with diabetes, pregnant women, and adults aged 65 and older. Patients with heart failure are highly likely to develop cardiopulmonary decompensation when infected with influenza, leading to serious complications or even death; therefore, in clinical nursing logic, prioritizing protection of patients with impaired cardiovascular function is a core strategy to reduce mortality.
