A British pharmaceutical giant is already manufacturing an unproven coronavirus vaccine as it hopes to dish out hundreds of millions of doses by September.
The Cambridge-based firm expects to have distributed hundreds of millions of doses of the vaccine this year and at least 2billion by mid-2021.
It has signed deals to produce 400million doses for the US and 100million for the UK if it is successful in human trials. Results are expected in August.
Britain has agreed to pay for the doses ‘as early as possible’ – with ministers hoping for a third of those to be ready for September if proven effective.
