Infectious Diseases, Prevention and Control

Vaccines and Immunization

A vaccination is a cellular preparation that gives you the protection you need against a specific infectious illness. A biological preparation of disease-causing bacteria is included in the vaccination. A weakened or destroyed version of the bacterium, one of its surface proteins, and its toxins are seldom used in this preparation. Immunization can be therapeutic (to treat a disease that has already developed, such as cancer) or preventive (to prevent the given disease) (to prevent or ameliorate the effects of a future infection by a natural or wild pathogen).
