Active Immunization

Active immunization is a method of providing protection against various diseases and infections. It involves the introduction of an antigen into the body to stimulate an immune response that produces antibodies that protect against future infections. Active immunization can be accomplished through vaccination, which introduces a weakened or inactivated form of a pathogen, or through the administration of an antibody-producing agent such as a recombinant protein. It is an important tool used in public health to prevent a wide range of infections and diseases, and has greatly reduced mortality rates in populations around the world.
