護理師評估個案的疫苗接種狀態。下列哪些疫苗通常建議 65 歲以上成人施打？（選所有適合的）

核心概念：成人（特別是老年人）的疫苗接種建議。 為何正確答案對： A. 肺炎鏈球菌疫苗（Pneumococcal vaccine）。老年人是肺炎鏈球菌感染的高風險族群，接種疫苗能有效預防侵襲性肺炎鏈球菌疾病，如肺炎、腦膜炎、菌血症。 B. 流感疫苗（Influenza vaccine, annual）。每年接種流感疫苗是老年人預防流感及其併發症（如肺炎）的標準建議，因為流感病毒株每年都會變異，且老年人免疫功能隨年齡下降。 D. 帶狀疱疹疫苗（Shingles vaccine, Herpes Zoster vaccine）。帶狀疱疹（皮蛇）的發病率隨年齡增加，疫苗能顯著降低發病風險及帶狀疱疹後神經痛的發生率。 為何其他選項錯： C. 水痘疫苗（Varicella vaccine）。水痘疫苗主要用於兒童或未曾感染過水痘的成人，以預防原發性水痘感染。對於 65 歲以上成人，除非有特殊情況（如未曾感染且有高風險），通常不作為常規接種項目，帶狀疱疹疫苗是針對潛伏的水痘病毒再活化。 E. BCG 疫苗（卡介苗）。BCG 疫苗是結核病（Tuberculosis, TB）疫苗，主要用於嬰幼兒或結核病高風險地區的人群，在美國等低結核病發生率國家，對成人（尤其是老年人）並非常規接種項目。 臨床思路/健康促進：疫苗接種是預防傳染病的重要公共衛生策略。針對老年人，由於免疫功能下降和慢性病共存，接種特定疫苗能顯著降低嚴重感染的風險，減少醫療負擔。護理師應熟悉最新的疫苗接種指南，提供準確的衛教。

Core concept: vaccination recommendations for adults, particularly older adults. Why the correct answers are right: A. Pneumococcal vaccine. Older adults are a high-risk group for pneumococcal infection; vaccination effectively prevents invasive pneumococcal disease such as pneumonia, meningitis, and bacteremia. B. Influenza vaccine (annual). Annual influenza vaccination is the standard recommendation for older adults to prevent influenza and its complications (such as pneumonia), because influenza strains vary year to year and immune function declines with age. D. Shingles vaccine (herpes zoster vaccine). The incidence of herpes zoster (shingles) increases with age; the vaccine substantially reduces the risk of developing shingles and postherpetic neuralgia. Why the other options are wrong: C. Varicella vaccine. The varicella vaccine is primarily used in children and adults who have never had varicella, to prevent primary varicella infection. For adults older than 65 years, it is usually not part of the routine schedule unless special circumstances apply (e.g., never infected and at high risk); the shingles vaccine targets reactivation of the latent varicella virus. E. BCG vaccine. The BCG vaccine is the tuberculosis (TB) vaccine, given mainly to infants and young children or to populations in high-TB-burden regions. In countries with a low TB incidence, such as the United States, it is not a routine vaccination for adults, especially older adults. Clinical reasoning/health promotion: Vaccination is an important public-health strategy for preventing infectious disease. For older adults, with their reduced immune function and coexisting chronic diseases, specific vaccinations substantially reduce the risk of serious infection and ease the burden on the health system. The nurse should be familiar with the most recent vaccination guidelines and provide accurate patient education.
