What is natural immunity?

Natural immunity refers to the body's inherent ability to defend itself against disease. This type of immunity is often partially inherited, meaning that certain genetic factors can influence an individual's immune response.

When discussing natural immunity, it’s important to understand that it encompasses the innate immune system, which comprises physical barriers, immune cells, and various molecules that the body is born with. These components work together to recognize and combat pathogens without prior exposure. Ultimately, this type of immunity is a fundamental part of the body's defense mechanism, providing a first line of response to infections.

In contrast, acquired immunity typically refers to immunity that develops after exposure to a specific pathogen, which can happen through infection or vaccination. Therefore, while options related to vaccination or exposure to pathogens may seem related, they do not accurately describe the concept of natural immunity as effectively as the idea of inherited resistance does.
