Health secretary says US would only share coronavirus vaccine once ‘needs of Americans’ are met

Trump administration health secretary Alex Azar declared today that any US-developed coronavirus vaccine would be shared with the rest of the world – but only after Americans’s needs have been served.Speaking to reporters on a visit to Taiwan, Mr Azar made clear that the the US government’s vaccine development programme – christened “Operation Warp Speed” – is principally aimed at tackling the domestic outbreak.
