For instance, Moderna’s mRNA vaccine directs the cell to make a surface protein found in the SARSCOVID-2 and then instruct the body’s immune system to rise against it. Instead, Novavax delivers the entire spike protein into the body using nanotechnology. This is called protein technology, found effective against Hepatitis-B.
