Denmark tightens lockdown in north over mink Covid outbreak

Twelve people infected so far with new strain against which vaccines may be ineffective

An outbreak among farmed mink of a mutant form of Covid-19 with the potential to be resistant to future vaccines has led to the Danish government bringing in tougher lockdown measures in parts of the country.

The measures were announced following the discovery of a new strain of the disease in animals bred for fur in the country's northern regions.
