Tieeeeens! Un expo sur les vaccins: ;D

•I will present my presentation on vaccines/vaccination,

A vaccination is a treatment which makes the body resist a particular infection.By giving someone a vaccine, the substance that makes their immune system react. The immune system is the way a body fights infection. The immune system's reaction makes someone less likely to get that infection. If the vaccinated person get exposed to the virus or bacteria that causes the disease, the person will fight it and may not get sick.
So vaccination and immunization have meanings that are a little different. But when people say these words, they usually mean the same thing. People say immunization to mean the same thing as vaccination.
