MICROANATOMY

Detailed explanation-1: -To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, mRNA vaccines use mRNA created in a laboratory to teach our cells how to make a protein-or even just a piece of a protein-that triggers an immune response inside our bodies.

Detailed explanation-2: -(ih-MYOON reh-SPONTS) The way the body defends itself against substances it sees as harmful or foreign. In an immune response, the immune system recognizes the antigens (usually proteins) on the surface of substances or microorganisms, such as bacteria or viruses, and attacks and destroys, or tries to destroy, them.
