So Harry goes to class to learn about spells that will help him fight Voldemort. He goes to Hogwarts
Yes exactly ! So let me explain how it works
Oh ! He will go to the class of defense against the dark arts ?
When Harry goes to class, he learns spells. Your body is like Harry, he needs to learn how to fight the bacteria
So a shot contain a part of the bacteria which is harmless, asleep if you prefer. When the body meets it, it will learn how to make cells (antibodies) that will help kill the bacteria by immobilizing them.
The body will remember these cells as the ones who help to kill that specific bacteria and if the real mean bacteria arrives, he will know how to fight it. It is the phagocytes that kill the bacteria, you can picture that as the wand
That's so cool ! I think I understand
See the antobides and phagocytes as the spells and the wand that Harry needs. With the shot, you help your body just like professor Lupin helped Harry learn about the patrons charm that saved his life.
Now I understand how important it is to have the shot. Thanks, Sarah for your really good explanation. It was really useful. I'll ask my mom to take an appointment at the doctors tomorrow. I really want to help my body kill Voldem... hum the bacteria I mean.
