mRNA VACCINES

mRNA acts as a cellular messenger. DNA, which is stored in a cell’s nucleus, encodes the genetic information for making proteins. mRNA transfers a copy of this genetic information outside of the nucleus, to a cell’s cytoplasm, where it is translated into amino acids by ribosomes and then folded into complete proteins. mRNA is a short-lived molecule, meaning it degrades easily and does not last long inside cells.

By injecting cells with a synthetic mRNA that encodes a viral spike protein, an mRNA vaccine can direct human cells to make a viral spike protein and evoke an immune response without a person ever having been exposed to the viral material.

These viral spike proteins, or antigens, normally coat the surface of the virus and are recognized by antibodies and other immune cells that prepare and protect the body against the virus. If a person is later exposed to the virus, antibodies and other parts of the immune system can recognize and attack the virus before it can infect healthy cells or cause illness.

Traditional vaccines work by giving a person either viral proteins or an inactivated or weakened version of a virus that triggers an immune response. mRNA vaccines do not contain viral material. Instead, these vaccines contain lipid or fat bubbles that surround a segment of mRNA, which provide cells with the instructions to make a certain viral protein

The above description is wonderfully simplistic in is narrative. Yet, the more detailed science outlines how mRNA is delivered or transported to the ribosomes of the cell which make unique proteins for the functioning of the body. Once the messenger RNA is given to the ribosomes the manufacture of 'Spike" proteins identical to those found on the COVID-19 virus, are made. This is the unique aspect of these new and novel vaccines that reverse engineer the pathogenic process. By making the healthy human cell and body make a foreign protein for the sole purpose of infection reduction is a new frontier in medicine. In so saying new frontiers also create new unforeseen risks.
