疫苗(Vaccine) 是指一類用于預防傳染性疾病的生物制品。其核心原理是通過模拟病原體或其特定成分(稱為抗原),安全地刺激機體(人或動物)的免疫系統,使其在不引發嚴重疾病的情況下,産生針對該病原體的特異性免疫應答(包括産生抗體和激活免疫細胞),并形成“免疫記憶”。當機體未來遭遇真正的同種病原體入侵時,免疫系統能夠迅速、有效地識别并清除病原體,從而預防疾病的發生或減輕疾病的嚴重程度。
疫苗的詳細含義和關鍵點包括:
疫苗的研發、生産和使用需遵循嚴格的科學規範和監管要求,以最大限度地确保其安全性和有效性。世界衛生組織(WHO)、各國疾病預防控制中心(如美國CDC)以及藥品監管機構(如美國FDA、中國國家藥監局NMPA)是疫苗相關信息的重要權威來源。例如,WHO在其官網上提供了關于疫苗安全性和不同類型疫苗的詳細信息(https://www.who.int/news-room/questions-and-answers/item/vaccines-and-immunization-what-is-vaccination),美國CDC也提供了疫苗工作原理的科普解釋(https://www.cdc.gov/vaccines/vac-gen/howvpd.htm)。
“vaccine”(疫苗)指一種通過刺激免疫系統産生特異性保護的生物制劑,主要用于預防傳染病。以下是詳細解釋:
如需了解具體疫苗的接種方案或科學原理,可進一步提問。
