Description
Lipid nanoparticles (LNPs) are microscopic structures used to deliver mRNA in COVID-19 vaccines. These particles encapsulate and protect the mRNA, facilitating its entry into cells. Once inside, the mRNA provides instructions for cells to produce a specific coronavirus protein, which triggers an immune response. This process prepares the body’s defenses against potential future infections with the actual virus.
However, researchers have raised concerns about potential risks associated with LNPs. These include unexpected distribution in the body, possible interactions with blood components leading to clotting issues, and theoretical risks of affecting cellular DNA. Some scientists have also reported finding contaminants in vaccine vials. While these vaccines have been administered to millions and have played a crucial role in pandemic management, experts emphasize the need for continued research to fully understand the long-term implications of this technology.
