Here the latest key developments at a glance: A government-backed study is being launched to determine whether people can be safely given different coronavirus vaccines for their first and second doses, with results expected “probably after the summe”, according to vaccines minister Nadhim Zahawi. The UK reported 915 further deaths on Thursday, as well as 20,634 new infections, slightly up from Wednesday’s 19,202 new cases. Over the past seven days, infections in the UK have declined by 25,7%. Zahawi declined to give a date for when the first nine groups in the priority list will have received their vaccine. Previously, NHS England chief executive Sir Simon Stevens has said the aim is for all over-50s and those at risk to be vaccinated by the end of April. Rob Paterson, chief executive of Best Western hotels, has criticised a lack of communication from the government over its plan to quarantine certain international arrivals in hotels, and said hotel bosses “to this day simply haven’t heard anything despite multiple offers”. The health secretary, Matt Hancock, will lay out the “operational plan” for hotel quarantines next week. “A significant return to normality” is on the cards once the most vulnerable groups have been vaccinated, Scientific Advisory Group for Emergencies (Sage) member professor Andrew Hayward said on Thursday, but Nadhim Zahawi told the Commons that the economny would only be reopened “very gradually”. Nadhim Zahawi told the Commons the UK government, despite having pre-purchased 300m coronavirus vaccine doses, was “nowhere near having enough supply” to send vaccines to poorer countries. The Welsh health minister, Vaughan Gething, said that there cannot be a “huge splurge of reopening” in the country despite Covid-19 rates falling since before Christmas. England’s infections fell by 29% in week to 27 January, as a total of 196,257 people tested positive for Covid-19 in England at least once in that week. Case rates in England have decreased in all age groups and are currently highest in those aged 30-39 years old, according to Public Health England. Around one in 10 major hospital trusts in England had no spare adult critical care beds last week, according to NHS England figures. A mutation of coronavirus initially detected in Liverpool has been found in Preston and West Lancashire, local health officials said on Thursday.
