Denmark Finds Covid Strain That Might Hamper Vaccine Effort

Denmark says it’s found a new strain of Covid-19 that might hamper efforts to develop a vaccine, after an outbreak in the country’s mink population triggered a mutation of the virus.

Prime Minister Mette Frederiksen told reporters that, because of developments in Denmark, there is now “a risk that the effect of a future vaccine will be weakened or, in a worst case scenario, be undermined,” during a virtual press briefing on Wednesday.
