Vaccination
The injection of a mild pathogen into a body to produce immunity
Real World Example
Imagine you're trying to prepare for a big presentation by practicing in front of a smaller, more forgiving audience. This is similar to how a vaccination works, where a mild version of a pathogen is introduced to your body so that your immune system can practice and prepare for the real threat. Just like practicing in front of a smaller audience helps you build confidence and readiness for the big day, the mild pathogen helps your immune system recognize and fight off the actual disease in the future.
