Immunity can be defined as a complex biological system endowed with the capacity to recognize and tolerate whatever belongs to the self, and to recognize and reject what is foreign (non-self).
Immunity is an extensive topic, worthy of an encyclopedia of its own. Here we cannot summarize the field in detail, but will identify key concepts. Body n Health discusses two component of immunity that is innate and adaptive.
This provides the first line of defense against infection. It is a rapid response (minutes); it is not specific to a particular pathogen. It has no memory and does not confer long-lasting immunity to a body. For example, when communicable and non-communicable diseases along with seasonal change brings cold, cough, mucus formation, indigestion, fever and other health problems, human immune system responds to stop such problems from spreading.

This provides a specific immune response directed at an invading pathogen. Following exposure to a foreign organism there is an initial effector response that eliminates or neutralizes a pathogen. Later re-exposure to the same foreign organism induces a memory response with a more rapid immune reaction that eliminates the pathogen and prevents disease.
For example, the pathogen identified as a novel coronavirus (COVID-19) affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization but for some it becomes life threatening.
Covid-19 vaccines have been tested by multiple drug administration authorities in the world. They are proven to be effective in reducing probability of contracting COVID-19. Once a person is vaccinated, body is much better prepared to shield off more viruses by making immune system stronger.
