Immunizations train your child's immune system to make antibodies to protect him or her from harmful diseases.The cells of both parts of the immune system are made in various organs of the body, including:Antibiotics can be used to help your child's immune system fight infections by bacteria.
Antibiotics were developed to kill or disable specific bacteria.
There they encounter a variety of chemical substances that may prevent their growth. These potential pathogens, which include Human skin has a tough outer layer of cells that produce Like the outer layer of the skin but much softer, the mucous membrane linings of the respiratory, gastrointestinal, and genitourinary tracts provide a mechanical barrier of cells that are constantly being renewed.

Stimulation of immune response by activated helper T cells.
These substances include chemicals whose protective effects are incidental to their primary function in the body, chemicals whose principal function is to harm or destroy invaders, and chemicals produced by naturally occurring bacteria.Some of the chemicals involved in normal body processes are not directly involved in defending the body against disease.
Some clonal cells differentiate into plasma cells, which are short-lived cells that secrete antibody against the antigen.
Using antibiotics for viral infections or using the wrong antibiotic to treat a bacterial infection can help bacteria become resistant to the antibiotic so it won't work as well in the future.

Fruit and vegetables provide them.
If antibiotics are stopped early, the bacteria may develop a resistance to the antibiotics and the infection may come back again. The antibodies stay in your child's body. The invader is killed inside the immune system cells.
These deterrents ensure protection against numerous germs and parasitic pathogens (fungi, nematodes, etc.
The immune system is an interactive network of lymphoid organs, cells, humoral factors, and cytokines.

The innate immune system is inherited and is active from the moment your child is born.
The lining of the Some microbes penetrate the body’s protective barriers and enter the internal tissues. Others form memory cells, which are longer-lived and which, by proliferating rapidly, help to mount an effective defense upon a second exposure to the antigen.
