mRNA therapy is an innovative medical approach that uses messenger RNA to instruct cells to produce specific proteins that can help prevent or treat diseases. The technology gained global attention through mRNA vaccines, but its potential extends far beyond infectious diseases. Researchers are exploring its use in cancer treatment, genetic disorders, and personalized medicine. While mRNA therapy offers advantages such as rapid development and targeted treatment, it also faces challenges related to stability, delivery methods, and long-term research. Understanding both the benefits and limitations of this technology provides valuable insight into its growing role in modern healthcare.
