Question

Quizplus · Accepted Answer

Active immunity is generated by the body's immune response to an antigen, either through natural exposure to the antigen (such as contracting a disease) or through vaccination. Vaccines contain weakened or inactivated forms of the disease-causing agent, which stimulate the immune system to produce antibodies and memory cells against the agent without causing illness. This results in long-lasting immunity against the disease.
