BEIJING (Global Times): It will take at least two to three years to achieve herd immunity against Covid-19 worldwide, leading Chinese respiratory disease expert Zhong Nanshan said, calling for global cooperation and unity in ending the pandemic.
Zhong made the remarks on Tuesday (March 2) at an event hosted by the University of Edinburgh and the Edinburgh Futures Institute, which was also attended by US top infectious disease expert Anthony Fauci.
As long as the virus is still prevalent in some countries, the worldwide epidemic situation cannot be controlled, Zhong said, adding that eliminating the pandemic needs efforts and decisions based on science and evidence from every country's decision makers.
Seeking global cooperation is not only a moral obligation but also an essential route for the globe due to threats posed by mutated virus variants.
"Successfully containing the pandemic in a single country is not enough. The virus would speed up its transmission in its process of mutation and overturn countries' success in fighting it," the Chinese expert said.
Echoing Zhong's opinion, Fauci agreed that global unity was needed to fight against the epidemic and examples of global cooperation in combating disease were seen with measles and polio.
There is no reason for countries not to launch global cooperation in fighting against the Covid-19 pandemic, Fauci said.
Zhong is against using some unscientific and inhumane ways of natural immunity to reach herd immunity.
With the development and marketing of vaccines, Zhong stressed that it will take at least two to three years to achieve herd immunity worldwide. - Global Times
