'Promising' signs for Covid-19 vaccines' efficiency against mutant strains: EMA head

As the EU's 27 member states scramble to contain the spread of new "mutant" strains of the Covid-19 virus, the head of the European Medicines Agency, Emer Cooke, tells FRANCE 24 that there are "promising" results from early studies into how well existing vaccines work against the new variants. The so-called "UK variant", otherwise known as strain B.1.1.7, transmits more easily from person to person and there are predictions that it will become the dominant strain within weeks.
