Global herd immunity to take 2-3 years

Global herd immunity against COVID-19 will take two to three years, China’s top respiratory disease expert said.
 

“With the development and marketing of vaccines, it will take at least two to three years to achieve herd immunity worldwide,” Zhong Nanshan said at an online conversation hosted by the University of Edinburgh on Tuesday night.
 

“Last year, two months after the epidemic was basically under control, we reopened our economy and resumed classes,” said Zhong, who was exchanging views with top US infectious disease expert Anthony Fauci during the event.
 

The duo urged global solidarity and cooperation to fight the COVID-19 pandemic.
 

Zhong and Fauci agreed that balancing economic development and epidemic prevention and control is a global challenge, and undue hasty return to the “normal life” might lead to a backlash of the epidemic.
 

“If we want to end this epidemic, we need appropriate science-based, evidence-based decisions by decision-makers in each country. Everyone should do their best. So we need global solidarity,” said Zhong, who is also an academician at the Chinese Academy of Engineering.
 

Meanwhile, Yang Xiaoming, the chief executive officer of China’s Sinopharm vaccine producer, said the company has completed COVID-19 clinical trials for groups aged 3-17 and will submit data for approval with authorities.
 

Yin Weidong, the chief executive officer of Sinovac, said the company’s production capacity will be expanded to 2 billion doses per year by June.
 

Both the vaccines have been rolled out and China has supplied the vaccines to nearly 30 countries so far.
 

世界范围群体免疫要2到3年!

北京时间3月2日21时,钟南山院士在广州出席由爱丁堡大学组织举办的国际疫情防控专家研讨会,与美国著名传染病学专家福奇博士进行连线对话,探讨全球抗疫合作等话题。
 

针对众说纷纭的“群体免疫”,钟南山院士表示不能够用一些不科学、不人道的“自然免疫”手段达到群体免疫效果。随着疫苗的研发和陆续上市,“我觉得至少要有2-3年的时间才能实现世界范围内的群体免疫”。钟南山院士认为,变异的病毒对疫情防控形成了巨大的挑战,也会让疫苗的效果大大降低。我们需要全球的合作,这样我们才能把我们的研究工作推进一步,也能够设计更好的疫苗来防止变异。”现在有些疫苗已经在研发中,中国已有3款疫苗被批准有条件上市,1款可在紧急的情况下使用。
 

钟南山院士表示,新冠病毒是全人类的敌人,假如新冠病毒还在个别国家蔓延,那么新冠肺炎疫情就不可能在全世界得到控制。这就意味着我们还要共同地面对新冠病毒。我们想终止这个疫情,就需要由每个国家的决策层基于科学、基于证据去进行恰当的决策,大家都尽最大的努力,所以我们需要全球的团结。
