mRNA Vaccine Technology

mRNA vaccine technology uses messenger RNA, a harmless genetic material, to instruct cells to produce a specific protein found on a virus, such as the spike protein of COVID-19. Once this protein is made, the immune system recognizes it as foreign and builds defenses against it. If the person later encounters the actual virus, their immune system is prepared to respond quickly. This approach is rapid to develop, highly effective, and does not involve introducing live virus, making it a powerful tool in infectious disease prevention.
