Boris Johnson has assembled his Cabinet in person for the first time in four months, as the Government presses ahead with plans to secure millions of doses of a potential Covid-19 vaccine.Senior ministers are meeting in the Foreign and Commonwealth Office rather than the smaller Cabinet room in Downing Street to allow for proper social distancing.It comes after a study suggested a Covid-19 vaccine being developed by the University of Oxford was safe and induces an immune reaction, which was branded “encouraging” by the scientific community.
