Is mrna harmful for humans?

mRNA (messenger RNA) itself is not inherently harmful to humans. It is a natural molecule that plays a crucial role in the process of translating genetic information into proteins, which are essential for various cellular functions. mRNA technology has been used in some modern vaccines, such as the Pfizer-BioNTech and Moderna COVID-19 vaccines. These vaccines use a small piece of synthetic mRNA to instruct cells to produce a harmless piece of the spike protein found on the surface of the virus that causes COVID-19. This prompts an immune response, helping the body recognize and fight the virus if it is encountered in the future. Studies and real-world data have shown that these mRNA vaccines are safe and effective for the vast majority of people. Common side effects are typically mild and short-lived, such as soreness at the injection site, fatigue, or mild fever. As with any medical intervention, there can be rare but serious side effects. However, the benefits of vaccination—such as preventing severe illness, hospitalization, and death from COVID-19—far outweigh the risks for most people. It's always advisable to discuss any concerns with a healthcare professional, who can provide personalized information based on an individual's health history and circumstances.
