华夏多地已经开展第三针加强针得疫苗接种工作，对此，华夏工程院院士钟南山在接受刘欣得专访时表示，目前华夏已有10亿多人接种了两针新冠疫苗，加强针接种应该继续增加，这样得话，明年上半年形成较好群体免疫得可能性就比较大了。而60岁以上得老年人接种率应该提高，因为老年人常常患有并发症，比较容易转成重型病例。

China's top epidemiologist Doctor Zhong Nanshan said about 80 percent of Chinese will have received two doses of the COV-19 vaccine by the end of 2021. With COV-19 booster shots, China is likely to achieve herd immunity in the first half of 2022. China also wants to produce more shots to help vaccinate the world.
