Core Tip
Core Tip: This cohort study assessed the long-term effects of the Johnson & Johnson coronavirus disease 2019 vaccine on metabolic markers in Ethiopian patients with type 2 diabetes mellitus. Key findings include temporary drops in high-density lipoprotein and total cholesterol levels post-vaccination, followed by recovery, whereas thromboxane levels showed lasting reductions, indicating potential thrombosis protection. The stability of triglycerides and prostaglandins underscores the vaccine's metabolic safety. These results contribute to understanding the vaccine's metabolic effects and highlight its safety and possible cardiovascular benefits for high-risk diabetic individuals.
