Clinical trials for China's vaccine Omicron variants are to conclude in three to four months, to the vaccine developer on Wednesday.

4月27日，国药集团中国生物称，针对新冠病毒奥密克戎变异株的疫苗临床研究工作预计需要3—4个月左右的时间来完成。

在即将开展的临床试验研究（clinical research）中，研究团队将高度关注疫苗是否能够激发人体产生针对奥密克戎的特异性的中和抗体。

Pre-clinical showed the vaccine has good neutralizing against Omicron variants. said Zhang Yuntao, chief scientist and vice of vaccine developer China National Biotec Group (CNBG), affiliated with Sinopharm, during an online conference.

国药集团中国生物**科学家、副总裁张云涛说，当前的研究结果显示，针对新冠病毒奥密克戎变异株的疫苗中，针对奥密克戎的中和抗体获得了很大幅度的提升。

Animal experiments have also shown the vaccine offers some against Omicron infections, he said, noting that the protective of the vaccine needs to be observed in clinical trials.

他说，动物试验也表明，该疫苗对奥密克戎具有一定的保护效果。他同时指出，该疫苗的防护作用需要在临床试验中进一步观察。

The vaccine was approved for clinical trials by the National Medical Products Administration on Tuesday.
