I have to get my tetanus shot tomorrow but I am really scared of shots !
You don't have to be afraid of vaccines, and I will tell you why. But for that, you need imagination!
Why do I need a vaccine if my body can already fight off these nasty germs ?
The product in your injection contains the microbe that causes tetanus disease. Once those nasty germs are in your body, your body will react quickly to fight them.
A lot of little soldiers, which are already in your body, will be requisitioned to fight them off. These soldiers are called white blood cells.
Listen to me carefully !
What makes this first fight so important ?
In the case of a vaccine, your body is able to fight the germ because it is injected weakened. This first fight that your body has against this germ is very important to be able to fight it again if more and stronger germs arrive.
During this first fight, your body will be able to detect the microbe's attack techniques. Each germ has a particular attack technique, called antigen.
Your body will create a special defense for this antigen : these defenses are antibodies in the blood and special white blood cells called memory cells.
So if I understand correctly, thanks to this vaccine,I'm going to offer the soldiers in my body defenses to fight off nasty germs that could make me very sick?
Exactly, that's why it's very important to make this shots, it can save your life! Tetanus is a very serious disease and it is necessary to protect yourself.
Yeah, thanks, shots are not as bad as I thought. Now,I feel great ready to fight off all those nasty germs!
