UK PM says vaccine a welcome boost to Covid fight
"We can't afford to relax," PM said on a visit to a central London hospital.
LONDON (AFP) - Britain’s Prime Minister Boris Johnson on Tuesday called the roll-out of a new Pfizer-BioNTech vaccine against Covid-19 a "tremendous shot in the arm for the entire nation".
But with most people not expected to get vaccinated until early 2021, he said the public still needed to be careful to stop the spread of the virus.
"We can’t afford to relax," he said on a visit to a central London hospital.
