Elderly with few antibodies may need an extra dose of COVID-19 vaccine: Study

The new mRNA vaccines have just as good a protective effect against COVID-19 for the very oldest as for younger people. This is evident in a study at Umeå University, where researchers have followed individuals in special housing around Sweden. However, the study shows that elderly people with a low antibody response after vaccination were at increased risk of dying from the omicron variants of the disease. The research is published in The Lancet Regional Health—Europe.
