Active Immunization- Advantages and Drawbacks


Active immunization is a process of stimulating the body`s immune system to produce antibodies and memory cells that can protect against specific infectious diseases. It can be achieved naturally by exposure to a pathogen or artificially by vaccination. Active immunization is different from passive immunization, which involves transferring antibodies from another source to provide temporary immunity. Active immunization has the advantage of being long-lasting and can be reactivated by a booster dose or a natural infection. However, it also has some drawbacks, such as requiring time to develop, being ineffective in some immunocompromised individuals, and having potential side effects or complications. In this article, we will discuss the various aspects of active immunization, including its types, routes, purpose, examples, advantages and drawbacks.
