莫德纳公司(Moderna Inc.)和辉瑞公司(Pfizer)在Covid-19疫苗的研究方面处于领先地位,两家的最后阶段临床试验结果预计将在未来几周内公布。此外,尽管在过去两个月中,三期试验出现了一些小挫折,但是好在牛津大学和阿斯利康公司研发的疫苗在老年人和年轻人中都产生了免疫反应。

然而,像Covid-19疫苗的这样的研发速度是前所未有的,因为疫苗通常需要10到15年的时间才能将疫苗投放市场。所以包括英国疫苗专责小组在内的专家们都表示:第一代疫苗“可能不完美”,“可能不适合所有人”。

据世界卫生组织(WHO)称,目前有150多种Covid-19疫苗正在研制中,大约44种候选疫苗正在进行临床试验,其中11种进行到了后期试验。

With the results of last-stage clinical trials by two Covid-19 vaccine frontrunners — Moderna Inc and Pfizer — expected in the coming weeks, hopes have risen of securing an antidote to the novel coronavirus by December itself as infections surge across the United States and Europe with the onset of winter. Moreover, despite minor setbacks during Phase III trials in the past two months, the vaccine developed by University of Oxford and AstraZeneca Plc has produced immune responses in both elderly and young people.

However, the unprecedented pace at which Covid-19 vaccines are being developed — it can typically take 10 to 15 years to bring a vaccine to market — has led experts, including the UK Vaccine Taskforce, to say that the first generation of shots “is likely to be imperfect” and that “might not work for everyone”.

According to the World Health Organization (WHO), more than 150 Covid-19 vaccines are presently in development, with around 44 candidates in clinical trials and 11 undergoing late-stage testing.  source
