QUESTION ADDRESSED BY THE STUDY: Do three coronavirus disease 2019 (COVID-19) vaccine doses induce a serological response in lung transplant recipients? METHODS: We retrospectively included 1071 adults (551 (52%) males) at nine transplant centres in France. Each had received three COVID-19 vaccine doses in 2021, after lung transplantation. An anti-spike protein IgG response, defined as a titre >264â
BAU·mL-1 after the third dose (median (interquartile range (IQR)) 3.0 (1.7-4.1)â
months), was the primary outcome and adverse events were the secondary outcomes. Median (IQR) age at the first vaccine dose was 54 (40-63)â
years and median (IQR) time from transplantation to the first dose was 64 (30-110)â
months. RESULTS: Median (IQR) follow-up after the first dose was 8.3 (6.7-9.3)â
months. A vaccine response developed in 173 (16%) patients. Factors independently associated with a response were younger age at vaccination, longer time from transplantation to vaccination and absence of corticosteroid or mycophenolate therapy. After vaccination, 51 (5%) patients (47 non-responders (47/898 (5%)) and four (4/173 (2%)) responders) experienced COVID-19, at a median (IQR) of 6.6 (5.1-7.3)â
months after the third dose. No responders had severe COVID-19 compared with 15 non-responders, including six who died of the disease. CONCLUSIONS: Few lung transplant recipients achieved a serological response to three COVID-19 vaccine doses, indicating a need for other protective measures. Older age and use of mycophenolate or corticosteroids were associated with absence of a response. The low incidence of COVID-19 might reflect vaccine protection via cellular immunity and/or good adherence to shielding measures.
