Human antibodies are Y-shaped molecules produced naturally by the body's immune system. They recognise, bind to and neutralise specific viruses and other pathogens. – AstraZeneca, What Science Can Do.

What is a monoclonal antibody?

Monoclonal antibodies are lab-made antibodies that mimic what your natural antibodies are able to do, and are most often used as a form of targeted therapy for specific kinds of cancer, but they've also been used throughout the pandemic to help fight off COVID-19. – Cleveland Clinic, April 2023

Vaccine History

Vaccines were first developed under a strategy to stimulate and imitate natural antibody production in the body. This artificial manipulation of the immune system by scientists became known as Acquired Immunity (vs Natural Immunity). However, vaccine-induced, immunity is not long-term or reliable. A tell-tale artifact of vaccines is that their protection wanes overtime.

So, scientists set out to create a "new and improved" vaccine.

Enter the mRNA experimental COVID vaccines! These injectables are a mix of proteins from different viruses from the Family Coronaviridae. They are not designed to stimulate antibody production, because they are not true vaccines. Scientists call this gene-therapy. They are also being used as Cancer therapy.
