In the Stomach, or Intestines (Look a little deeper), there is some bacteria that helps with digestion, because they speed up the process. The Immune System recognizes this, and basically leaves them to do their job.

The Immune System is the defense network of the body. The immune system works with specific receptors on specialized cells - detecting foreign bodies and signaling for the immune system to destroy them.
The immune system is the body's defense system that helps fight off bacteria and viruses. It is made up of a network of cells, tissues, and organs that work together to protect the body from harmful pathogens.
Bacteria deals with the entire immune system, Archae deals with a different type of body system.
An organism's immune system protects it from harmful bacteria and other organisms. In terms of the Human immune system, this includes leukocytes (white blood cells of various types) and the various parts of the lymphatic system.
The immune system protects the body from infection by creating a barrier that prevents viruses and bacteria from entering the body. If the virus and bacteria enters the body, the immune system detects and eliminates them before they can reproduce.
Bacteria that enter the body can be destroyed by the immune system through mechanisms like white blood cells, antibodies, and inflammation. The immune response works to identify and attack the invading bacteria to prevent infection and illness. Antibiotics can also be used to kill bacteria directly in certain infections.
Vaccines are given because they keep you from getting sick. They work by preparing your immune system to fight bacteria by themselves. A dead, or weak, strain of the bacteria is given to the body. Your immune system can then produce anti bodies to kill them. Your system can then remember how it did it. If you should get a virrulent strain in future, an effecient attack can then be launched automatically.
