Vaccination and immunization are closely related concepts that play a crucial role in protecting individuals and communities from infectious diseases. Vaccination: Vaccination refers to the process of administering vaccines to stimulate the immune system and develop immunity against specific diseases. Vaccines contain weakened, inactivated, or pieces of the disease-causing microorganisms (pathogens) or their toxins. When a person is vaccinated, the immune system recognizes these harmless antigens in the vaccine as foreign invaders and mounts an immune response. This response includes the production of antibodies and memory cells that "remember" the pathogen. If the person is later exposed to the actual disease-causing pathogen, their immune system can quickly recognize and mount a strong defense to neutralize or eliminate the pathogen before it causes illness. Immunization: Immunization is the process of becoming immune or protected against a particular disease through vaccin...

Immunity refers to the body's ability to defend itself against harmful substances, pathogens, and foreign invaders, thereby protecting the body from various diseases. It is a complex system involving various organs, cells, and molecules working together to recognize and eliminate potentially harmful agents. There are two main types of immunity in the human body: 1. Innate Immunity:    Innate immunity is the first line of defense against pathogens and foreign substances. It is a non-specific form of immunity that provides immediate protection. Innate immunity is present from birth and does not require previous exposure to a specific pathogen to be activated. Some key components of innate immunity include:     Physical Barriers: Skin, mucous membranes, and other physical barriers prevent pathogens from entering the body.    Chemical Defenses: Enzymes and chemicals in body secretions (e.g., tears, saliva, stomach acid) can kill or inhibit the growth of pathoge...
