President Donald Trump says the US will reopen, “vaccine or no vaccine”, as he announced an objective to deliver a coronavirus jab by year end.
He likened the vaccine project, dubbed “Operation Warp Speed”, to the World War Two effort to produce the world’s first nuclear weapons.
But Mr Trump made clear that even without a vaccine, Americans must begin to return to their lives as normal.
Many experts doubt that a coronavirus jab can be developed within a year.
