2024 PN NCLEX Questions Nursing Practice Question
What type of immunity do vaccines provide?
Correct Answer: A
Rationale: Vaccines provide active immunity by stimulating the body's immune system to produce its own antibodies in response to a specific pathogen. This leads to long-lasting protection.
Option B, passive immunity, occurs when antibodies are transferred from one individual to another, such as through breast milk or injections, providing temporary protection without the immune system's involvement.
Option C, transplacental immunity, refers specifically to antibodies passed from mother to fetus during pregnancy, which is not the mechanism used by vaccines.
Option D combines both active and passive immunity, which is inaccurate as vaccines solely induce active immunity.
