What is the Most Efficient and Cost-Effective Way to Control

Question

What is the most efficient and cost-effective way to control infectious diseases?
A) variolation
B) active immunization by vaccination
C) passive immunotherapy using immunoglobulins
D) immune testing
E) autoimmunization

Accepted Answer

Active immunization through vaccination is the most efficient and cost-effective way to control infectious diseases. Vaccination creates immunity against infectious diseases by stimulating the immune system to produce antibodies and memory cells to fight off future infections. This reduces the risk of the disease spreading and can ultimately lead to eradication of the disease. Variolation, passive immunotherapy, immune testing, and autoimmunization are not as effective or cost-efficient as vaccination.
