When you get a disease and fight it off, your body produces specific antibodies for that disease, tiny organisms meant for that specific disease. While those antibodies remain in your system, you can't contract that same disease again.
Vaccinations are modified versions of the disease that they wish to produce immunity against. They produce a very toned-down effect of the actual disease, but cause your body to create the same antibodies, as if you'd had the real thing.
It is called a vaccine, which helps stimulate the body's immune response to produce immunity against specific diseases.
If a person's immune system is producing antibodies against a specific antigen, then that person has a positive or active immunity toward that antigen. If a person has merely been injected with antibodies but does not produce them, that is a passive immunity.
The process of immunity is to produce specific antibodies that bind to antigens on the surface of pathogens. =]
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.
Vaccines are used to produce immunity by causing the body to generate antibodies. The antibodies can be directed against the organism causeing the illness or against a toxin produced by the organism. Also some allergies are treated by causing the body to develop blocking antibodies. In most cases injections are used to give the treatment. Oral polio vaccine is one exception to this.
A substance prepared from killed or weakened microorganisms is called a vaccine. When introduced into the body, vaccines trigger the immune system to create a defense mechanism that provides immunity against specific diseases. This helps the body recognize and effectively combat the actual infectious agent if encountered in the future.
You exhibit Active Immunity when cells encounter anitgens and produce antibodies against them.
Gelatin vaccines are effective in preventing the spread of infectious diseases by stimulating the immune system to produce antibodies against specific pathogens.
Injecting a person with a vaccine to stimulate the body to produce antibodies against a disease is an example of active immunity. This type of immunity occurs when the immune system is exposed to a harmless form of the pathogen, prompting it to generate a specific immune response. Unlike passive immunity, where antibodies are transferred from another source, active immunity involves the individual's own immune system actively producing antibodies.
Vaccines are introduced into the body to stimulate the immune system to produce antibodies against a specific pathogen, such as a virus or bacteria. This helps the body recognize and fight off the pathogen more effectively if it is encountered in the future, providing immunity against the disease.
I'm not an expert, but from what I can gather, vaccinations are used for both virus' and pathogenic bacteria (harmful bacteria). Vaccines contain a section/segment of the virus or bacteria (for example a flagella) to infect the body. The body then produces memory cells so that the body has an immunity against the virus or bacteria (note that this immunity may not last a lifetime).
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.
