疫苗（vaccines）是通過模拟病原體或病原體成分，刺激人體免疫系統産生特異性免疫應答的生物制劑。其核心原理是提前訓練免疫細胞識别病原特征，形成免疫記憶，從而在真實感染時快速啟動防禦機制（世界衛生組織）。
現代疫苗技術主要分為四類：
疫苗的開發需經過三期臨床試驗驗證安全性與有效性，平均耗時5-10年。據聯合國兒童基金會數據，疫苗每年可預防200-300萬兒童死亡。當前全球疫苗監管體系以WHO預認證和FDA審查為基準，确保産品符合國際質量标準。
“vaccines”（疫苗）是用于預防傳染病的生物制劑，通過模拟病原體刺激免疫系統産生特異性抗體和記憶細胞，從而在未來接觸真實病原體時快速反應。以下是詳細解釋：
疫苗通常含有滅活/減毒的病原體、病原體成分（如蛋白質或遺傳物質）或類毒素。它們不會引發疾病，但能訓練免疫系統識别特定抗原，形成長期免疫記憶。
如需進一步了解疫苗技術原理或具體疾病防控案例，可提供更具體方向。
