COVID and Everything About Immunity

How Does Natural Immunity Work?

Your immune system, which is made up of many immune cell types and reactions, signals, and connections, works to keep you healthy. The concept of natural immunity—the extent to which your body can defend against a natural infection—is one of the types of immunity that has received the most attention in the wake of the epidemic.
How does “natural immunity” work? What distinguishes it from passive immunity? What can you do to prepare your immune system to fight SARS-CoV-2 effectively? Read on to find out.

“Natural Immunity” Explained

Natural immunity is what an individual has by default after contracting an infection naturally. Active, natural immunity, in contrast to vaccine-induced immunity, is not established by a triggered response to a vaccination against a disease.
By itself, immunity refers to the body’s capacity to defend itself against all infectious diseases, including COVID-19. Antibody therapy—the news-grabbing monoclonal antibodies that made headlines for the majority of the COVID pandemic—can provide passive immunity.
They are intended to provide uninfected people with an immunological edge without exposing them to the coronavirus. This immunological exposure primes the immune system for a later, real-world encounter, enabling the body to promptly and efficiently defend itself against sickness.

How Does COVID’s Built-in Immunity Function?

In a broad sense, an immune response is your body’s primary line of defense against foreign infections, or microbes, that could harm you. It accomplishes this by locating infections and linking them to distinctive, physiologically recognizable antigens, which are distinctive protein structures on the disease’s surface.
Any living thing, including bacteria, viruses, and fungi, has its own distinctive antigen profile. Antigens can also be identified in other, inanimate incursions, such as glass fragments or hazardous chemicals. These antigens enable your immune cells to focus on anything that needs to be eradicated, maintaining overall health and avoiding pathogens from harming organs, tissue, or other bodily structures.
The coronavirus spike protein, “S,” one of the most noticeable exterior structures discovered on SARS-CoV-2 post-Omicron, is one that your antiviral antibodies may quickly target. In reaction to this easily recognizable structure, your body creates COVID-specific antibodies, which play a significant role in your body’s natural immunological response.
The “S” spike protein’s two subunits, S1 and S2, are utilized to bind to fresh, uninfected host cells. By completely disabling the structure, your antibodies can stop viral invasion at the cell level.
Your body stores the experience as an immunological memory after encountering the pathogen and recovering. Currently, antibodies created specifically to combat SARS-CoV-2 are just present in your body, ready to combat any newly discovered coronavirus viruses.

Immunity – Innate and Adaptive

Innate, universal immunity, which defines a person’s real natural immunity to all infections and diseases, and adaptive, specialized immunity, which is the category that “natural immunity” as we understand it post-COVID belongs into, are the two categories into which immunity can be classified.
The innate immune system is more about how the human body spontaneously maintains itself as clean, pure, and free of invaders than it is about the alchemy in your blood. This term encompasses your actual first line of defense, which is the skin organ itself, in a broad sense.
Every solid membrane enclosing your body, including your skin, can be thought of as a life-saving wall of protection. The innate immune system is regarded as “nonspecific,” which means that, wherever possible, it protects against all invaders. Your adaptive resources are alerted when there is a problem by this alert system, but it has little power to stop the spread of disease throughout the body.
In part, the innate immune system stimulates and directs the adaptive immune response. Your body’s adaptive defenses only come into play when the innate immune system is unable to handle the COVID situation.

How To Enhance Your Resistance Against COVID-19

What, in the end, is the greatest strategy to keep your immune system strong and prepared to fight COVID infection?
The following lifestyle choices, per the CDC, can all strengthen immune defense against any infection, including SARS-CoV-2:

  • Consuming wholesome, nutritious foods
  • Upkeep of a healthy weight
  • Getting enough sleep
  • Avoiding bad habits like smoking and binge drinking
  • Vitamin C
  • Regular exercise
  • Drinking lots of water

Of course, another excellent piece of advice is to test frequently, especially when experiencing symptoms or following a potential exposure. It’s crucial to get medical attention if you do contract COVID-19. Get in touch with us today.
