An active immunization is a type of immunization in which the body is exposed to a foreign agent, such as a virus or bacteria, which triggers an immune response. This produces antibodies, which are proteins that recognize and neutralize foreign agents, and the body becomes immune to the agent. This type of immunization is also known as active immunity or active immunization.
Active immunization can occur naturally when a person is exposed to a pathogen, such as a virus or bacteria, and their body develops antibodies against it. This is why some people become immune to a disease after having it once. It can also occur artificially through a vaccine, in which a weakened or inactive form of the pathogen is introduced to the body. This triggers an immune response, and the body produces antibodies against the pathogen.
Active immunization is considered the most effective type of immunization, as it produces a long-lasting immunity to the pathogen. This type of immunization also produces a stronger immune response than passive immunization, which is a type of immunization in which antibodies are directly administered to the body.
Active immunization is used to protect against many infectious diseases, including measles, mumps, rubella, polio, and hepatitis B. It is recommended that children receive vaccines containing these pathogens, as they are the most effective way to protect against these diseases.
