By Press Association 2021 Royal Navy personnel prepare to give vaccines to the public at a coronavirus vaccination centre set up at Bath Racecourse (Ben Birchall/PA) People may be able to hug their loved ones in June, a Government scientific adviser has said, as a new study shows a single jab cuts virus transmission by up to half. Dr Mike Tildesley, from the University of Warwick and a member of the Scientific Pandemic Influenza Group on Modelling (Spi-M) group, suggested the decision on whether social distancing would be needed going into the summer months could be a political one. However, he said vaccines were doing the job of preventing most people falling seriously ill, and he was hopeful hugs would be back on the agenda by the date the Government has set for lifting legal limits on social contact.
