The SARS-CoV-2 mutation now rapidly spreading across England’s South East is potentially up to 70% more infectious than its predecessor—but not necessarily more dangerous, according to a new 

Could a novel strain of SARS-CoV-2 identified this month be linked to an accelerating spread in the country’s southeast? 

WHO advisors are meeting today to discuss deliberately infecting young, healthy volunteers with SARS-CoV-2 to hasten vaccine development—despite the promising vaccines already on the way.   Pros: Faster results than conventional vaccine field trials…
