Professor Jason Leitch warns first dose of coronavirus vaccine only offers about 30% protection from ‘horrid’ Delta variant

Scotland’s national clinical director stressed the need to get both vaccinations to offer “decent” protection and suggested eight to 10 weeks of progress thanks to the vaccine had been “lost” because of the variant, first identified in India. Speaking on the BBC’s Good Morning Scotland, Prof Leitch said the new strain of Covid-19 has “changed the game” in terms of the vaccine rollout because of the lack of protection offered by the first dose alone.
