Quizplus · Accepted Answer

The concept of herd immunity refers to the protection of an entire community (or herd) from a contagious disease when a critical mass of individuals become immune to it, either through vaccination or prior infection. When a high percentage of individuals in a population are immune to a contagious disease, the spread of the disease is slowed or stopped, even among those who are not immune. This provides indirect protection to unvaccinated or vulnerable members of the population, such as infants or individuals with weakened immune systems. Herd immunity is an important factor in controlling the spread of infectious diseases and preventing outbreaks.
