Covid-19 vaccinations to be available 24/7, Johnson says
Dates and venues for round-the-clock jabs were not immediately available

Coronavirus vaccinations will be made available on a 24-hour basis in the UK "as soon as we can", prime minister Boris Johnson has said.
The announcement represents yet another government U-turn, after Downing Street this week brushed off Labour calls for night-time opening of vaccine centres, saying there was "no clamour" for it, reports the Independent.
UK Ministers rethought plans after coming under intense pressure to step up vaccination rates, with one source saying that a pilot of longer hours was being planned to gauge the scale of demand.
Dates and venues for round-the-clock jabs were not immediately available.
Labour leader Sir Keir Starmer pressed Mr Johnson for 24/7 opening at prime minister's questions in the House of Commons.
Sir Keir said he had visited a vaccine centre in Newham, east London, last week to see the "uplifting" work of NHS staff, Red Cross and volunteer workers.
