A recent study has found that COVID-19 vaccination reduces the risk of severe kidney damage in patients hospitalized with COVID-19. Vaccinated patients who developed acute kidney injury (AKI) during hospitalization were less likely to require dialysis and had better survival rates compared to unvaccinated patients with similar conditions. The study included 972 participants who developed AKI, revealing that unvaccinated patients had 2.56 times higher odds of needing continuous renal replacement therapy (CRRT) after discharge, 5.54 times greater risk of dying in the hospital, and 4.78 times higher risk of death during long-term follow-up compared to vaccinated individuals. These findings suggest that COVID-19 vaccines provide protective benefits against severe renal complications associated with the virus. Additional research has also explored adverse events related to mRNA COVID-19 vaccines, including rare autoimmune and neurological conditions, but the protective effect against kidney injury remains a key outcome of this study.
