Simply changing the recipe to better target virus mutations will not require repeating those studies in thousands of people, said Dr. Peter Marks.

只改变疫苗配方来更好的针对变异病毒，这种做法不需要在很多人身上进行重复研究，彼得·马克斯如是说道。

The country will stick to its strategy of preventing imported infections and domestic flare-ups while refining its virus containment measures by stepping up the capabilities of port cities, intensifying studies into virus mutations and continuing the mass vaccination campaign.

中国将坚持外防输入、内防反弹，不断优化完善防控措施，加强口岸城市疫情防控，加大对病毒变异的研究，持续做好疫苗接种工作。
