从美国到澳洲，科学家们正在采用新技术和耗费巨资，要在创纪录时间内研发出可对抗2019新型冠状病毒（简称新冠病毒）的疫苗。

一般上，研制疫苗须要数年时间，而且过程冗长，包括在动物身上进行测试、在人类身上进行临床试验，以及等待监管当局的批准。

不过，多组专家在一个旨在对抗新病毒的国际联盟的支持下，希望缩短研发时间，而澳洲科学家就希望在6个月内达成此项任务。

为了加速疫苗的开发，由各国政府和慈善机构组成的“创新应对流行病联盟”（CEPI），已经为全球的四个研发项目投入了数百万美元的资金，同时还发出了征集更多提案的呼吁。

这些项目希望采用新技术来研制出可在近期内进行测试的疫苗。联盟总裁哈切特说，目标是在16周内进行临床试验。
