Antibiotics vs. Vaccines — What's the Difference?
By Tayyaba Rehman — Published on January 14, 2024
Antibiotics are drugs used to treat bacterial infections by killing or inhibiting bacteria, while vaccines are biological preparations that provide immunity against specific diseases, usually viral.

Key Differences
Antibiotics are medicinal drugs used to treat bacterial infections by killing or inhibiting the growth of bacteria. They are ineffective against viruses. On the other hand, Vaccines are biological preparations that stimulate the immune system to recognize and combat pathogens, particularly viruses.
The role of Antibiotics is primarily therapeutic, used after an infection has occurred. In contrast, Vaccines are preventative, administered before infection to build immunity and prevent the onset of diseases.
Antibiotics work by targeting various bacterial structures or processes, while not affecting the host's cells. Vaccines, however, introduce a weakened or inactivated form of a pathogen, or parts of it, to train the body's immune system.
Overuse or misuse of Antibiotics can lead to antibiotic resistance, a significant global health concern. Vaccines do not contribute to resistance but require periodic updates to remain effective against evolving pathogens.
Antibiotics are usually administered when a specific bacterial infection is diagnosed. Vaccines are part of public health programs for widespread immunization against common infectious diseases.

Antibiotics
A substance, such as penicillin or erythromycin, produced by or derived from certain microorganisms, including fungi and bacteria, that can destroy or inhibit the growth of other microorganisms, especially bacteria. Antibiotics are widely used in the prevention and treatment of infectious diseases.
Vaccines
A preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure, that is administered to prevent or treat infection by the pathogen and that functions by stimulating the production of an immune response.
Antibiotics
Of or relating to antibiotics.
Vaccines
A preparation from the cowpox virus that protects against smallpox when administered to an individual.
Antibiotics
Of or relating to antibiosis.
Vaccines
(Computers) A software program designed to detect and stop the progress of computer viruses.
Antibiotics
Destroying life or preventing the inception or continuance of life.
