Bacterial vaccines
A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
Bacterial vaccines contain killed or attenuated bacteria that activate the immune system. Antibodies are built against that particular bacteria, and prevents bacterial infection later. An example of a bacterial vaccine is the Tuberculosis vaccine.
