疫苗(Vaccine) 是指一类用于预防传染性疾病的生物制品。其核心原理是通过模拟病原体或其特定成分(称为抗原),安全地刺激机体(人或动物)的免疫系统,使其在不引发严重疾病的情况下,产生针对该病原体的特异性免疫应答(包括产生抗体和激活免疫细胞),并形成“免疫记忆”。当机体未来遭遇真正的同种病原体入侵时,免疫系统能够迅速、有效地识别并清除病原体,从而预防疾病的发生或减轻疾病的严重程度。
疫苗的详细含义和关键点包括:
疫苗的研发、生产和使用需遵循严格的科学规范和监管要求,以最大限度地确保其安全性和有效性。世界卫生组织(WHO)、各国疾病预防控制中心(如美国CDC)以及药品监管机构(如美国FDA、中国国家药监局NMPA)是疫苗相关信息的重要权威来源。例如,WHO在其官网上提供了关于疫苗安全性和不同类型疫苗的详细信息(https://www.who.int/news-room/questions-and-answers/item/vaccines-and-immunization-what-is-vaccination),美国CDC也提供了疫苗工作原理的科普解释(https://www.cdc.gov/vaccines/vac-gen/howvpd.htm)。
“vaccine”(疫苗)指一种通过刺激免疫系统产生特异性保护的生物制剂,主要用于预防传染病。以下是详细解释:
