Detailed explanation-1: -’Herd immunity’, also known as ‘population immunity’, is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection.

Detailed explanation-2: -Herd immunity occurs when a large portion of a community (the herd) becomes immune to a disease. The spread of disease from person to person becomes unlikely when herd immunity is achieved.

Detailed explanation-3: -Herd immunity refers to the resistance of an entire group of people to a disease as a result of the presence, of many immune individuals [6].

Detailed explanation-4: -Herd immunity applies to immunisation or infection, human to human transmitted or otherwise. On the other hand, herd effect applies to immunisation or other health interventions which reduce the probability of transmission, confined to infections transmitted human to human, directly or via vector.
