Explain the principle of herd immunity.

What is immunological tolerance and why is it important?

Solution

Explain the principle of herd immunity.

Herd immunity is a form of indirect protection from infectious disease that occurs when a large community has become immune to an infection, thereby providing a measure of protection for individuals who are not immune. Herd immunity arises because there are so few susceptible people left to infect.
