Human Immune System

We are continually looking for examples of intelligence and design in the world around us. One of the most incredible examples is the human immune system.

During the 2020 pandemic, we have all heard discussions among the experts about antibodies and how they can protect us from COVID-19. Scientists have also talked about who is vulnerable to the virus and herd immunity. We may not have thought about how our bodies were designed to fight diseases, virtually all of which come to us from animals.

Built into the human body is the ability to produce antibody proteins whenever a harmful antigen enters the body. This protein is a Y-shaped molecule that destroys the antigen. The antigen can be bacteria, fungi, parasites, or viruses. Once the antibody enters the bloodstream, it can last for a very long time.

More recent studies of people who survived the 1918 flu virus (which killed 50 million people worldwide) showed that survivors still had the antibodies in their blood years later. Dr. Eric Altschuler at the University of Medicine in New Jersey said, “Our immune system has a steel-trap memory. It’s incredible that the Lord has blessed us with antibodies our whole lifetime. What doesn’t kill you makes you stronger.”

The question arises as to whether this means we should let people get the COVID-19 virus until we all have antibodies to prevent getting it again. The problem with that view is that this virus can do great harm to our bodies, even if we survive it. The virus can perhaps also mutate and be re-introduced to our bodies.

We should never underestimate new challenges to our health, but the incredibly complex human immune system is designed to enable us to live in a world of challenges. Design requires a Designer.
