United Kingdom Prime Minister Boris Johnson said there was no reason to delay reopening the economy on Tuesday, as the country races to fully vaccinate all adults in an effort to quell the rapid spread of the Delta COVID-19 variant.The Delta variant, which is a more transmissible strain of COVID-19 first identified in India, is quickly becoming the more dominant strain in Britain.
Officials said the variant accounts for up to three-quarters of newly reported cases as parts of the country undergo a surge in infections, leading to 3,165 confirmed cases on Wednesday.As several provinces begin reopening, some experts say Canada could stand to tweak its vaccination campaign to give high-risk Canadians their second doses faster.
