In the context of health:
* Immune: Protected from a particular disease or infection, typically through the body's natural defenses or through vaccination. This means the body can recognize and fight off the disease-causing agent.
* Immune system: The complex network of cells and organs in the body that defends against disease. It includes white blood cells, antibodies, and organs like the spleen and lymph nodes.
In other contexts:
* Immune: Not susceptible to something, like a particular influence or effect. For example, "He is immune to criticism." This means he doesn't care or is not affected by criticism.
For a more specific definition, please provide some context. For example:
* "What does it mean to be immune to a virus?"
* "What does it mean to be immune to peer pressure?"
Once you provide context, I can give you a more accurate and relevant definition.
