Vaccines work by training your immune system to recognize and fight specific germs (like viruses or bacteria) without making you sick.

 

Vaccines work by training your immune system to recognize and fight specific germs (like viruses or bacteria) without making you sick.

Here’s how it works in simple steps:

1. Introduction of a harmless part of the germ:
   A vaccine contains a small, safe piece of the disease-causing organism—this could be a protein, a dead or weakened form of the germ, or its genetic material.

2. Immune system response:
   Your immune system sees this as a threat and creates antibodies to fight it off—just like it would during a real infection.

3. Memory cells are created:
   After the fake “infection” is gone, your body keeps a memory of the germ. If you’re ever exposed to the real thing, your immune system can respond quickly and effectively, often preventing illness altogether.

In short:
🛡️ Vaccines safely prepare your body to fight disease—before you ever encounter it.
