Verified step by step guidance

Understand the concept of acquired immunity: Acquired immunity refers to the immune response that develops after exposure to a specific antigen or through vaccination.

Differentiate acquired immunity from innate immunity: Innate immunity is present at birth and provides immediate defense against infection, whereas acquired immunity is developed over time after exposure to antigens.

Consider the role of vaccination: Vaccination is a method to artificially induce acquired immunity by exposing the body to a harmless form of the antigen, prompting the immune system to develop a memory of it.

Recognize the types of acquired immunity: Acquired immunity can be active, where the body produces its own antibodies, or passive, where antibodies are transferred from another source, such as through breast milk.

Identify the correct definition: Based on the explanation, acquired immunity is the immunity that develops after exposure to a specific antigen or after vaccination.
