What term describes the resistance of a group to an attack by a disease?

The term that accurately describes the resistance of a group to an attack by a disease is herd immunity. This concept refers to the level of immunity in a population that helps prevent the spread of infectious diseases. When a significant portion of the population is immune, either through vaccination or previous infections, the movement of the disease is limited, making it difficult for the disease to spread. This protection not only helps those who are immune but also safeguards those who may be vulnerable, such as individuals who cannot be vaccinated for medical reasons.

Herd immunity is a crucial public health goal because it creates a buffer that can protect entire communities from outbreaks, thus lowering the incidence of disease even among those who are not immune. Understanding this concept is vital for health professionals when considering vaccination programs and disease control strategies.
