根据7月20日在医学期刊《柳叶刀》上发表的最新研究，在我国进行的一款新冠候选疫苗的二期临床试验发现，该疫苗是安全的且可以诱发免疫反应。

"The phase 2 trial adds further evidence on safety and immunogenicity in a large population than the phase 1 trial. This is an important step in evaluating this early-stage experimental vaccine and phase 3 trials are now underway," said Professor Zhu Fengcai from Jiangsu Provincial Center for Disease Control and Prevention.

江苏省疾病预防控制中心的朱凤才教授表示，与一期临床试验相比，二期临床试验提供了该疫苗在大规模人群中的安全性和免疫原性证据。这是评估早期实验疫苗的重要步骤，目前该疫苗正在进行三期试验。

According to The Lancet, the trial of the Ad5 vectored COVID-19 vaccine candidate was conducted in Wuhan with 508 participants taking part.

根据《柳叶刀》，这项Ad5载体新冠候选疫苗的试验是在武汉进行的，508名受试者参与其中。

Approximately two-thirds of participants were aged 18-44 years, with a quarter aged 45-54 years, and 13% aged 55 years or older.

约2/3的受试者年龄在18-44岁之间，1/4受试者年龄在45-54岁之间，13%受试者的年龄在55岁或以上。

Since elderly individuals face a high risk of serious illness and even death associated with COVID-19 infection, they are an important target population for a COVID-19 vaccine, said Professor Chen Wei, an academician with the Chinese Academy of Engineering and a researcher at the Institute of Military Medicine under the Academy of Military Sciences.
