Oh, that's not a big deal you know... and that is very helpful for your body !
How?... It hurts, thath's all !
Why don't you come into my office? I will explain to you why it is important to get vaccinated.
Inside vaccines there are antigens that cause the disease, they are most often weakend version of bacteria or virus. Once in your body, it triggers the body's immune system to produce antibodies against microbes. In the meantime, memory cells and lots of other cells fight the same microbes.
That sounds great !
All in all, it act like a shield, it is called immunization.
Absolutely, and it protects you from very bad diseases which may make you very sick, even kill you...
So, after the vaccine, the disease is no longer able to hurt me?
Alright then I'm ready for the shot. I don't want to be sick for summer and I want to play whereever I want without risking to catch a disease.
Will do ! Thank you, doctor !
Eventually it didn't hurt that much...
I'm glad you have understood what was a stake ! Enjoy your summer and tell your friends about it !
