Re: 曾毓群，马斯克，和我决定以后好一点
阿毛真倔强。疫苗是否能救人要看具体的疫苗类型、疫苗的使用方式、以及疫苗的剂量。COVID-19 mRNA 疫苗就不再罗嗦了，反正你只愿意相信你想相信的。
在COVID-19大流行早期，强生/阿斯利康推出的病毒载体COVID-19疫苗可导致一种罕见但严重的血栓性疾病，即血栓伴血小板减少综合征 (TTS)。因此该病毒载体COVID-19疫苗被禁止使用。
Dengvaxia (登革热疫苗): 如果将该疫苗用于既往未感染过登革热的人群，它可能起到初次感染的作用，通过一种称为抗体依赖性增强的机制，增加被免疫者日后发展为重症、危及生命的登革热的风险。因此，世界卫生组织和美国疾病控制与预防中心 (CDC) 限制该疫苗仅用于有实验室确诊既往登革热感染证据的人群。
Viral Vector COVID-19 Vaccines (Janssen/AstraZeneca): Early in the COVID-19 pandemic, these specific viral vector formulations were found to cause a rare but serious blood-clotting condition known as thrombosis with thrombocytopenia syndrome (TTS).
Dengvaxia (Dengue Vaccine): Research showed that if given to individuals who had never previously contracted dengue, the vaccine could act like a primary infection. This increased their risk of developing a severe, life-threatening case of dengue later through a mechanism called antibody-dependent enhancement. Consequently, the World Health Organization (WHO) and the CDC restrict its use exclusively to people who have lab-confirmed proof of a past dengue infection.
