Question

In order for the herd effect/herd factor to protect a population from a disease outbreak, approximately ? of the population must be immunized.

A) 10%
B) 50%
C) 75%
D) 95%

Answer 1

Herd immunity is achieved when approximately 75% of a population is immunized, providing protection against a disease outbreak.

Step-by-step explanation:

Herd immunity is a phenomenon that occurs when a critical portion of a population is immunized against a disease, protecting even those who have not been immunized. In order for herd immunity to effectively protect a population from a disease outbreak, approximately 75% of the population must be immunized. This prevents the disease from spreading effectively throughout the population. Vaccination programs play a crucial role in maintaining herd immunity and reducing the number of susceptible individuals in a population.
