specific immunity
Acquired immunity (also known as adaptive immunity) This immune reaction is quite fast due to the immune memory.
The administration of a vaccine stimulates the body to produce a longer lasting type of immunity called "adaptive immunity." This type of immunity involves the production of specific antibodies and memory cells that provide long-term protection against the targeted pathogen.
Acquired immunity: When a person gets sick from a disease, their body produces antibodies to fight off the infection. After recovery, the body retains memory cells that recognize the specific pathogen if it reappears, providing immunity against future infections.
Active immunity
It is an acquired immunity
Specific immunity follows a non-specific response. The major difference between specific and non-specific is the ability to remember pathogenic antigens. Specific immunity results in the production of memory cells which upon reinfection are used to effectivly remove the pathogen Non-specific cannot do this
Specific immunity
Immunization provides specific immunity by introducing antigens from pathogens into the body, which stimulates the adaptive immune system to produce specific antibodies and memory cells tailored to those antigens. This memory allows for a rapid and robust response upon future exposure to the same pathogen. Additionally, the process can also enhance non-specific immunity by activating innate immune responses, such as the production of cytokines and the recruitment of immune cells, which provide a broader defense against various pathogens. Thus, immunization fortifies both arms of the immune system.
Adaptive Immunity is the type of immunity that creates memory cells. This is a specific type of immunity that reacts to the "non-self" antigen of pathogens. In the initial or first introduction to the pathogen, Immunoglobulin M (IgM) predominates the circulation. But in thesubsequentintroduction of the same pathogen where in memory cells were already formed from the previous event, Immunoglobulin G (IgG) now predominates. These antibodies either neutralize pathogens directly, or signals the complement system and/or the Natural Killer cells to eliminate the pathogen.Since memory cells are already formed, the body is better equipped in dealing with the same pathogen the second time around.This is the same concept in vaccinations, wherein we introduce into the body the same pathogen but in a weakened form removing it's virulence.

The two types of immunity are innate immunity and adaptive immunity. Innate immunity is the body's first line of defense and includes physical barriers like skin, as well as immune cells that respond to general threats. Adaptive immunity is more specific and involves the production of antibodies and immune memory to target particular pathogens.
