China's top health authorities on Sunday urged local authorities to halt mandatory vaccination orders as some cities were reportedly found to adopt compulsory measures to meet the country's goal of vaccinating 560 million people by June.
 

Officials and experts said the instances were rare and do not reflect the big picture, but it reveals management problems in some local governments that need to be alert. They stressed that the country's principle is to encourage those in need to get vaccinated while respecting their wishes.
 

The recent mass inoculation plans have been carried out in two key sectors. The first aims to ensure mass vaccination in potential high risk areas such as port cities, border areas and metropolises where epidemic outbreaks have occurred, and the second covers key worker groups including cold-chain workers, medics, governments and institutions, schools, supermarkets and logistics, Wu Liangyou, deputy head of the National Health Commission (NHC)'s disease control bureau, told a press conference on Sunday.
 

China is taking an approach of "getting the people who need it vaccinated and pushing forward vaccination in stages," and as of Saturday, the country had administered 164.47 million jabs, making it the second-fastest country in the world in terms of mass vaccination, according to the press conference.
 

According to estimates from disease control experts, vaccination coverage would need to reach 70 to 80 percent of a population for herd immunity, which in China means about 900 million to 1 billion people would need to be vaccinated.
 

我国想建立免疫屏障可能要10亿人以上接种疫苗

我国目前正在应接尽接、按梯次,对重点地区、重点人群、重点城市加快推进新冠疫苗接种。多少人接种才能建立免疫屏障?接种疫苗能不能再等等?国疾控中心免疫规划首席专家王华庆,就相关问题进行解读。
 

多少人接种新冠疫苗才能建立免疫屏障?
 

从3月24日起,中国启动新冠疫苗接种数据的日报制度,国家卫健委每日在官网公布疫苗接种总数,这也是人类疫苗接种史上首次启动国家级最大规模的日报制度。
 

王华庆:我国要建立免疫屏障,可能需要10亿以上的人接种新冠疫苗,接种率越高,免疫屏障就越牢固。
 

打疫苗可不可以再等等?
 

王华庆:如果大家都把接种疫苗往后拖,那么免疫屏障就永远建立不起来,我们想摘掉口罩的愿望可能就不会实现。如果大家接种得快,这个屏障可能就会早一天到来。要尽早恢复到正常的生活,疫苗是目前的最佳选择。
 

接种新冠疫苗对阻止病毒变异有什么作用?
 

王华庆:如果疾病一直蔓延下去,病毒变异的速度就会变快,相对的,疾病的严重程度和传染性都会增加。阻止病毒变异速度加快的最好办法就是接种疫苗,接种疫苗后我们有了免疫力,就不会成为传染源,病毒就传播不下去了。
 

疫苗的安全性能达到百分之百吗?
 

王华庆:任何一个疫苗都有它的风险,我国接种新冠疫苗后有不良反应或者严重过敏性反应的,约为百万分之一,而新冠肺炎的病亡率为2%。可以看出感染新冠肺炎给我们带来很大的危害,而疫苗是可以采取一些措施把风险降到最低。
