Expert: Dynamic clearance policy is like life insurance

China's dynamic zero-COVID strategy provides a significant safety net for its people against the virus, and the country is within the window of opportunity to defeat the epidemic driven by the highly infectious Omicron strain, a senior health expert said on Friday.

Stronger efforts should be devoted to accelerating vaccination, strengthening the emergency response capacity and expanding the use of effective drugs, said Liang Wannian, head of the National Health Commission's virus control expert panel.

"China's dynamic clearance policy is like life insurance for its 1.4 billion people against threats of the virus and uncertainties posed by its constant mutations," he said at a news conference held by the State Council Information Office.
