How does the immune system of children work?
What is the immune system?
The immune system protects your child’s body against external invaders. These include bacteria (such as bacteria, viruses, and fungi) and toxins (chemicals made by microbes). The immune system consists of various organs, cells and proteins that work together.
There are 2 main parts of the immune system:
–The innate immune system. You were born with this.
–The adaptive immune system. You develop this when your body is exposed to microbes or chemicals released by microbes.
These 2 immune systems work together.
The innate immune system
This is your child’s quick response system. It is the first to respond when he finds an intruder. It consists of the skin, the cornea of the eye and the mucous membrane that covers the respiratory tract, gastrointestinal tract and urogenital tract. These all create physical barriers to help protect your child’s body. They protect against harmful bacteria, parasites (such as worms) or cells (such as cancer). The innate immune system is inherited. It is active from the moment your child is born. When this system detects an intruder, it immediately takes effect. The cells of this immune system surround and cover the intruder. The invader is killed in the cells of the immune system (called phagocytes).
The acquired immune system
The acquired immune system, using the innate system, makes cells (antibodies) to protect your body against a specific invader. These antibodies are developed by cells, called B lymphocytes, after the body has been exposed to the intruder. The antibodies remain in your child’s body. Antibodies may take a few days to form. But after the first exposure, the immune system will recognize the intruder and defend itself against it. The acquired immune system changes during the life of your child. Immunizations train your child’s immune system to make antibodies to protect him or her from harmful diseases. Your child must start building up resistance to all kinds of specific pathogens after birth. That build-up happens when your child first comes into contact with such a specific pathogen. The body then produces antibodies and immune cells against that specific intruder. After that first time, the immune system remembers how to approach that pathogen. So if the same germ penetrates the body again later, the immune system immediately recognizes that and immediately directs those specific immune cells to it.
Because a child’s immune system still needs to be built up, it is inevitable and necessary that a child becomes ill. It seems beneficial to have that happen at a young age. Research among young day care children (under 2.5 years of age) shows that they do indeed have fewer infections in primary school than their classmates who stayed at home or went to a childminder. The favorable long-term effect disappears for toddlers who go to day care at a later age. They also have a lot of snot noses and runny ears, but do not reap the benefits of this later in life.
Although it is inevitable that a child becomes ill, you can do something about it. With Natriche Immune Kids, the pathogen in the child’s body will be tackled faster and more effectively. As a result, the child will have fewer symptoms of a cold or flu, for example, and the symptoms will be less severe. As a result, the parents are less likely to fall ill. The child’s immune system will remember this pathogen and recognize it later, so the child builds up a good resistance after all.
