Flow chart of lung transplant recipients (LTR) recruitment and antibody response to COVID-19 mRNA-based vaccination. The study was conducted on 136 LTR, including 10 and 126 patients with and without history of COVID-19 before vaccination, respectively. Sera sampled after each vaccine dose in COVID-19-naive patients were analyzed to assess the anti–receptor-binding domain (RBD) IgG response, with seropositive patents defined as responders.
