Summary
Fine needle aspiration of lymph nodes in humans, reveals that SARS-CoV-2 vaccination induces neutralizing antibody-producing germinal centers, enhanced by repeated vaccination. Conversely, in patients receiving immunosuppressant medication, this process is disrupted resulting in stunted protective immune responses highlighting issues about vaccine and booster efficacy in patients with compromised immune systems.
