Safety is a paramount concern in vaccine development, and mRNA vaccines have undergone rigorous testing in clinical trials. The results have demonstrated that these vaccines are safe for use, with common side effects including pain at the injection site, fatigue, and mild fever. These side effects are generally short-lived and indicative of an immune response. Moreover, mRNA vaccines do not interact with an individual's DNA, as the mRNA does not enter the cell nucleus. This addresses a common misconception about genetic alteration.
