How The Immune System Protects You

How The Immune System Protects You

The immune system’s function is to protect against microorganisms that cause disease, and its objective is to keep a person healthy. The immune system is a massive and composite connected network of different proteins, cells, and organs that protect the body from illness. Having a healthy immune system can defeat invading germs that cause disease and cancer cells while protecting healthy tissue. Understanding how immunity works and how it can help defend the body is vital to the fight against COVID-19.

Two Main Parts of the Immune System;

1. Innate Immunity

Innate immunity mainly consists of physical barriers on and in the body. It is active as soon as you’re born. The main feature of this is to respond fast, which can lead to fever and inflammation. It doesn’t recognize exact strains of viruses, but it attacks mostly, so it cannot get rid of all pathogens.

2. Acquired or Adaptive Immunity

The immune system also learns things. If the immune system is visible to a new germ for the first time, it responds by fighting off, making you sick. Nevertheless, afterward, the immune cells will remember the invader and be better equipped to fight it.

Key Players of the Immune System

The white blood cell, also called leukocyte, is one of our most important immune system players. Leukocytes patrol the tissues and blood throughout the body in search of intruders. They send out a signal and launch an immune attack if they detect a foreign substance. These disease-fighting cells are stored in many different places in the body and made in the bone marrow.

Immune System Being Active

Everything that initiates an immune response is called an antigen. It can be a microbe that comes from outside of the body. An antigen comes into the body, and B-cells recognize it, B-cells will create antibodies. When antibodies attach to an antigen, it signals other parts of the immune system to attack and destroy the invaders. It is how the human body develops immunity to a particular disease.

Why Vaccine Matters For COVID-19

Vaccines prompt the immune system to create disease-fighting antibodies, which benefits from an acquired immunity without getting sick first. They introduce antigens in the form of an inactivated virus into the body to stimulate the immune system.

In the case of the new coronavirus, it has never been in humans. Wherein, if it contracted to people, it may have to go through the full immune process to fight it off. COVID-19 might lead to serious health effects for some. People with a compromised immune system, underlying health condition, taking medications, or other factors tend to be most ill. Having a weaker immune system could make people less able to fight off illness, putting them at a greater risk of problems from COVID-19. However, if every individual had a way to teach our bodies to fight the virus and skip sickness, and could help the world move closer to a healthier place. By this time, research is ongoing to find the right vaccines to allow that to happen.
