A group of scientists from the University of Gothenburg has gone another step forward in their quest to learn how the immune system acquires resistance to COVID-19. According to the findings from a new study a hidden immune feature helps the unvaccinated defeat Covid.
156 personnel from five primary care health institutions were enlisted during April and May 2020, and the scientists at the University's Sahlgrenska Academy researched them for six months.
