Active immunization is that where an antigen penetrates into the body triggering the primary immune response and generation of the memory lymphocytes and antibodies which offer faster and more effective immune defence in the future infections by same antigen. Passive immunization is that where the immunoglobulins against an antigen are inoculated within the body to offer the protection in case, the body becomes infected by the antigen. Active immunization is generally longer lasting as compared to the passive immunization as within the active type as well as the antibodies, specific memory lymphocytes stay in the circulation. In passive immunization, duration of protection is that of the duration of antibodies in circulation.
