通用冠状病毒疫苗猴子试验有效
冠状病毒 疫苗 猴子 自然
2021/6/3
美国科学家在日前出版的《自然》杂志上撰文称，为了防止未来的冠状病毒大流行，他们最近研发了一种“泛冠状病毒”疫苗，旨在抵御多种已知会感染人类和蝙蝠的冠状病毒。试验显示，这种新疫苗在猴子身上非常有效，但尚不清楚能否为人类提供同样的保护。研究报告主要作者、杜克大学人类疫苗研究所研究主管凯文·桑德斯说，虽然没有人知道哪种病毒会引发下一场大流行病，但冠状病毒“绝对是威胁”。过去几十年来，“大约每8年就有一种...
哈佛大学最新研究，酒精或是COVID-19传播的潜在帮手

随着新冠病毒肆虐全球，一些国家和地区开始流传喝酒可防新冠的谣言，使人们在恐慌中丧失辩识力，造成不可挽回的悲剧。为此，世界卫生组织（WHO）还曾发出过一份警告驳斥了“引用高强度酒精可以杀死”新冠病毒的说法，并表示“酒精会破坏人体免疫系统，增加健康风险，可能引发一系列传染性和非传染性疾病，因此任何时候都应尽可能减少对酒精的摄入，在疫情期间尤其如此”。
