This is important so that we are not taken unawares by the next pandemic, when not if it comes, he said. Sage, the group of scientists advising the UK Government, have said vaccines do not provide absolute sterilising immunity. Prof Reddy said: Covid-22 could get worse than what we are witnessing now. (b) The earliest detections from several different countries are close in time and there is no clearly demonstrated travel link to a specific country that explains the detections.
