Dialysis patients benefit from a third COVID vaccination dose

Just like diseases, vaccines cause the body to form an immunological memory. This memory can prevent a second infection or illness caused by the same pathogen. "Put simply, specific immunity is based on antibodies that prevent infection and on immune cells that can kill infected cells," explains Professor Nina Babel, head of the Center for Translational Medicine specialized in immunology. With her colleagues, she has developed a technique that allows insight into the state of the immune system. To this end, the researchers determine in a test tube, so to speak, whether a person has functioning antibodies and immune cells against a certain pathogen.
