Johnson says evidence UK virus strain more deadly

The coronavirus strain that has swept Britain and beyond in recent months could be more deadly as well as more transmissible, Prime Minister Boris Johnson said on Jan. 22. 

The sobering news came as the U.K. sees record deaths from Covid-19, following a surge in cases and hospitalizations since the variant was first identified in southeast England in September.

When to Expect Coronavirus Vaccine?

When will we have a Covid-19 vaccine? Public-facing scientists such as the UK's chief scientific adviser, Sir Patrick Vallance, and his US counterpart, Anthony Fauci, keep repeating that it won't be before 12 to 18 months. But other voices - including some of those in the race to create a vaccine themselves - have suggested that it could be as early as June. Who is right?
