Spike Proteins

 Traditional vaccines are produced from actual viruses grown most often in chicken eggs. Viruses are then weakened or killed and injected directly into our bodies inducing an immune response. Now, a new class of mRNA vaccines delivers to human cells a set of genetic instructions, blueprints, to produce viral spike proteins that trigger our body’s immune response. These generated viral spike proteins preview what any real viruses’ spike proteins will look like. Antibodies, once programmed, then recognize the proteins on the surface of invading pathogenic cells. They bind to the invader’s spike proteins, blocking the virus from using them to penetrate our healthy respiratory cells.
