Date Time Positive signs of immunity after COVID-19 infection Australian scientists have described the evolution of immunity levels up to four months following COVID-19 infection, finding that while antibody levels drop dramatically in the first one to two months, the decrease then slows down substantially. The findings suggest that protective COVID-19 vaccines should ideally generate stronger antibody responses than natural infection. The research, led by Professor Stephen Kent from the Doherty Institute in collaboration with the University of New South Wales Kirby Institute and Flinders University, has been published in high ranking journal Nature Communications, The team, including University of Melbourne Dr Jennifer Juno, a Senior Research Fellow at the Peter Doherty Institute for Infection and Immunity (Doherty Institute), have been investigating how the immune system, particularly B and T cells, responds to the COVID-19 spike protein.
