Covid-19: Vaccines 'needed across world to reduce chance of new variants'

Coronavirus vaccines must be made available around the world in an effort to keep cases down and prevent new mutations which could escape the effects of the jabs, an expert has warned. Sir Jeremy Farrar, a member of the British government's Scientific Advisory Group for Emergencies (Sage), said the amount of virus circulating in the world will determine the chances of a new variant emerging. He said new strains are 'a warning of what is coming, which we must take incredibly seriously' and suggested countries with access to vaccines could donate a percentage of their doses through the international Covax drive which aims to ensure equitable access.
