More than 80% of adults in England and Wales would test positive for Covid antibodies, according to figures released by the Office for National Statistics this morning. The figures are lower for Northern Ireland (79.9%) and for Scotland (72.6%).
Having antibodies can protect people from further infection. People acquire antibodies either through vaccination, or from being infected in the past. But antibody levels do not correspond to the total number of people vaccinated and infected in the past because over time antibody levels reduce to the point where they are no longer detected in tests.
