Vaccinated COVID-19 Patients Show Better Outcomes in Acute Kidney Injury Cases, Study Reveals
June 13, 2025
A recent study highlights the outcomes of vaccinated versus unvaccinated patients hospitalized with COVID-19, particularly focusing on those who developed acute kidney injury (AKI).
The research analyzed data from approximately 3,500 hospitalized COVID-19 patients between early March 2020 and the end of March 2022, with 972 of them experiencing AKI.
Among the AKI patients, 411 were unvaccinated while 467 had received at least two doses of Pfizer or Moderna vaccines or one dose of Johnson & Johnson.
Acute kidney injury is a significant complication in COVID-19 patients, occurring in up to 46% of cases and potentially leading to severe complications or long-term kidney function decline.
However, the study faced limitations, including missing baseline creatinine data and a lack of information regarding the severity of COVID-19 illness among the patients.
Despite these limitations, the study underscores the need for ongoing research to better understand the impacts of COVID-19 on kidney health and to improve management strategies, as emphasized by Dr. Nobakht.
This study is particularly timely as discussions around COVID-19 vaccinations are reigniting, especially following recent changes in vaccine recommendations by Health and Human Services Secretary Robert F. Kennedy Jr.
Findings indicated that vaccinated patients who developed AKI had better outcomes, experiencing lower risks of dialysis and death compared to their unvaccinated counterparts.
Specifically, 15.8% of unvaccinated patients required continuous renal replacement therapy (CRRT), compared to 10.9% of vaccinated patients.
