WHAT IS IMMUNIZATION? Vaccination consists of introducing an agent (a bacterium, virus or molecule) into the body that has been deprived of its pathogenicity (its ability to make you ill) but has kept its immunogenicity (its ability to induce an immune response). In case of a subsequent contact with the pathogen agent, the body will be ready to defend itself, thus protecting the vaccinated individual against the disease.
