"While this meta-analysis concludes that lockdowns have had little to no public healtheffects, they have imposed enormous economic and social costs where they have been adopted," the researchers wrote. "In consequence, lockdown policies are ill-founded and should be rejected as a pandemic policy instrument."
The researchers – Johns Hopkins University economics professor Steve Hanke, Lund University economics professor Lars Jonung, and special advisor at Copenhagen's Center for Political Studies Jonas Herby – analyzed the effects of lockdown measures such as school shutdowns, business closures, and mask mandates on COVID-19 deaths.
"We find little to no evidence that mandated lockdowns in Europe and the United States had a noticeable effect on COVID-19 mortality rates," the researchers wrote.
