Vaccines are like a special boot camp for your body's defense system, also known as your immune system. They help teach your immune system how to fight off diseases.
Here’s how vaccines work:
Meeting Antigens: Vaccines give your body a safe version of a germ (this could be a weakened or killed virus) or pieces of it, called antigens.
B and T Cell Activation: When your body sees these antigens, special cells called B cells produce antibodies that help fight germs. T cells work to find and destroy infected cells.
Making Memory Cells: After your body fights off the harmless germ, it creates memory cells. Think of them as soldiers that are ready to jump into action if the real germ shows up again.
Fast Reaction: If your body encounters the real germ later, your immune system can react quickly and effectively, which helps keep you from getting sick.
In this way, vaccines help your immune system learn to protect you for a long time!
