Why do I have to get a shot, Doctor? I’m not even sick!
In order to understand how immunizations help you, you need to know a bit about your blood.
Blood carries tiny cells to all parts of your body. There are fat, disk-shaped red cells. There are white cells, too. The white cells have a special job. They fight germs and kill them. White cells keep you well. When germs get in, your white blood cells go to work. But some germs are too strong for an unprepared body. When a doctor gives you a shot, or immunization , this helps your white cells prepare for certain kinds of germs. Shots are like a fire drill. A fire drill gets you ready in case of a real fire. A shot gets you ready in case of a real attack by germs.
We give kids shots to protect them.
To understand that, you need to know a little more about how your body works.
Protect them? How?
White blood cells are larger than red blood cells, and they eat germs.
Germs can get into your body in many ways. They can enter through your mouth or through your nose, or even through a cut in your skin.
