Explanation: 

Detailed explanation-1: -Active Immunity Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.

Detailed explanation-2: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader.

Detailed explanation-3: -If you’re wondering why vaccine-induced immunity is considered a form of active immunity, while immune globulin shots are passive, it is because immune globulin is a substance made up of antibodies that are naturally made by the body to provide protection from certain diseases.

Detailed explanation-4: -Adaptive immunity: Adaptive (or active) immunity develops throughout our lives. We develop adaptive immunity when we’re exposed to diseases or when we’re immunized against them with vaccines.
