Yes, everyone is born with a type of immunity called innate immunity.
Understanding Innate Immunity
Innate immunity, also known as natural immunity, is a general protective system present from birth. This system provides the first line of defense against harmful invaders, like bacteria and viruses. Think of it as your body’s built-in security system, always ready to respond.
How Innate Immunity Works:
- Physical Barriers: The skin is a prime example, acting as a barrier to prevent germs from entering the body.
- Recognition: The immune system can recognize certain foreign substances that are potentially dangerous.
Examples of Innate Immunity:
- The skin preventing germs from entering the body.
- The body's ability to recognize harmful substances.
Types of Immunity
While everyone is born with innate immunity, it is important to note that there are other types of immunity:
- Adaptive Immunity: This is immunity developed over time by exposure to germs, either through infection or vaccination. This type of immunity is specific to the germs that the body has been exposed to and allows the body to build long-term protection.
Key Takeaway
While we are all born with innate immunity, other forms of immunity are developed later through exposure to germs. Innate immunity is like a general defense, while adaptive immunity provides a more targeted defense.
