对抗新冠病毒的疫苗研发，传出佳音。美国生技药厂莫德纳(Moderna)18日公布第一阶段人体实验结果，身体健康的志愿者接受疫苗注射之后，体内产生了抗体。

莫德纳表示，期盼接下来的研究顺利进行，最早在今秋就能让疫苗可以出炉，做为紧急之用。
值得注意的是，莫德纳的第一阶段人体实验规模较小，接下来还需要后续阶段的更多研究。
总部位于麻州莫德纳指出，第一阶段人体实验的重点在于确认疫苗安全无虞。至于这款疫苗是否可以让民众注射之后，可以完全免于遭到新冠病毒感染，也就是具备绝对的预防效果，则有待更多研究。
新冠病毒全球大流行之后，世界各国科学家、医学专家彷彿在疫苗研发领域展开赛跑。以过去疫苗研发过程来看，从开始研究到最后核准上市，通常耗时数年，但川普政府日前表示，疫苗可望在今年底之内问世。

疫苗竞赛

面对美国的连番指责，中国外交部发言人曾表示，中国在新冠疫苗研究和治疗方法方面“走在世界前列”，没有证据的诬陷造谣“是不道德的”。
那么，这场由疫情引发的疫苗“军备竞赛”，美国和中国究竟处于什么样的水平？
据世界卫生组织网站数据，目前全球有超过120个正在研发的新冠病毒疫苗项目，已经进入临床试验的共有8个。其中，来自中国的项目4个，美国2个。此外，还有一个来自英国牛津大学的项目和一个跨国合作的项目。
这些项目采用了不同的研发路径，包括核酸疫苗（DNA和RNA）、病毒载体疫苗和灭活疫苗等。
目前，它们中的大部分项目都获得了一二期合并的临床试验许可。由中国公司康希诺生物（CanSino Biologics）与中国军事医学研究院合作的疫苗已在4月进入二期临床试验阶段。
在美国，马萨诸塞州的生物公司摩德纳（Moderna）已在上周获得美国食品药品监督管理局（FDA）的批准，进入二期临床试验阶段。
在治疗药物方面，被外界给予厚望的“神药”瑞德西韦（Remdesivir）已获得美国当局授权，在治疗新冠重症患者时得以紧急使用，该药物也在日本获批并交付医院使用。
