A vaccination is a type of preparation that teaches the immune system to recognize a disease-causing agent through the introduction of a weakened or dead form of the pathogen, a part of the pathogen, or a similar but harmless substitute.

Antibiotics and sulfa drugs are medications used to treat infections, while analgesics are pain relievers. Injection is a method of administering a medication or vaccine, but not a type of preparation.
