"The Covid-19 vaccine developed at Oxford University works perfectly and builds strong immunity to the virus, a study shows. Great hopes rest on the vaccine, which is a global frontrunner and has been shown to safely trigger an immune response in volunteers given it in early trials. But, unlike traditional vaccines which use a weakened virus, or small amounts of it, the innovative Oxford jab causes the body to make part of the virus itself. Now researchers led by the University of Bristol have found this daring technology works for the coronavirus, just as it has for similar viruses in the past. A study using cells in the laboratory found the vaccine effectively delivers the instructions for the Covid protein, which cells copy thousands of times to produce it in large amounts. This means a person's immune system is then primed to recognise the disease and fight it off without them falling ill."
