How do we avoid another coronavirus lockdown?
Probably the most interesting new bit of information we received today on Covid-19 was from Sir Patrick Vallance, the chief scientific adviser, who implied that he and the government are now assuming that fewer than one in 200 people who are infected with the virus will die. That still means this form of coronavirus is a terrible scourge. It is not exactly conventional good news. But this Infection Fatality Rate of 0.4 per cent is less than half the circa one per cent he and the chief medical officer Chris Whitty employed as their rule of thumb or heuristic only a few months ago.
