Sumario:The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine booster is one of the most essential strategies against coronavirus disease 2019 (COVID-19) in the era of emerging variants. However, the effectiveness of SARS-CoV-2 vaccine boosters has not much been investigated in hemodialysis (HD) patients receiving oral antiviral agents. In this retrospective study involving 258 HD patients with COVID-19 receiving molnupiravir, we stratified the study cohort according to vaccination status and compared the baseline characteristics and risks of 30-day composite events (COVID-19-related acute care visits, hospitalization, or mortality) among groups. Our analysis demonstrated that the SARS-CoV-2 vaccine boosters markedly decreased the risk of composite events in HD patients (hazard ratio (95% confidence interval), 0.163 (0.063–0.423) for three vs. ≤ two doses of vaccination, p < 0.001; 0.309 (0.115–0.830) for four vs. ≤ two doses of vaccination, p = 0.020). The benefits of vaccine boosters were similar between patients receiving mRNA-based and protein-based boosters and between those with post-booster intervals of ≤ 120 and > 120 days. In conclusion, for HD patients with initially mild or asymptomatic COVID-19 receiving molnupiravir, the benefits of SARS-CoV-2 vaccine boosters are prominent, irrespective of booster vaccine types.
