護理師指導家長關於嬰兒預防接種時間表。關於小兒疫苗，下列哪項資訊正確？
A nurse is teaching a parent about immunization schedules for an infant. Which information is correct regarding pediatric vaccines?
- AImmunizations are only necessary for infants who attend daycare僅就讀托兒所的嬰兒才需要接種疫苗
- BVaccines are essential for preventing communicable diseases and providing herd immunity✓ 正解疫苗對於預防傳染病及建立群體免疫至關重要
- CInfants should wait until they are older to receive multiple vaccines嬰兒應等到較大年齡再接種多種疫苗
- DMost childhood vaccines have severe, long-term side effects大多數兒童疫苗具有嚴重且長期的副作用
疫苗接種是公共衛生中預防傳染病最有效的初級預防（Primary Prevention）策略。透過廣泛的疫苗接種，不僅能保護個體免受病原體侵襲，還能建立群體免疫（Herd Immunity），保護那些因年齡過小、免疫功能不全或過敏而無法接種的弱勢族群。護理師應強調疫苗的安全性、效益遠大於風險，並依據 CDC 建議的時間表接種，以確保免疫力在疾病暴露前建立。
Vaccination is the most effective primary prevention strategy in public health for preventing infectious disease. Widespread vaccination not only protects the individual from pathogen invasion but also establishes herd immunity, protecting vulnerable populations who cannot be vaccinated because of young age, immunocompromise, or allergy. The nurse should emphasize that vaccine safety and benefits far outweigh the risks and that the CDC-recommended schedule should be followed to ensure immunity is established before exposure to disease.
台美在常規疫苗時程上高度相似，皆依據 CDC 或衛福部規範。差異點在於美國護理師在臨床教導時，更強調「延遲接種（Delayed vaccination）」可能導致的法律責任與社會風險，且美國對於疫苗猶豫（Vaccine Hesitancy）的衛教溝通更具結構化。
