Antibiotics vs. Vaccines: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on January 9, 2024
Antibiotics are drugs used to treat bacterial infections, while vaccines are substances used to stimulate the immune system to prevent diseases.
Key Differences
Antibiotics are medications designed to combat bacterial infections. Vaccines, on the other hand, are biological preparations that provide active acquired immunity to particular diseases.
The primary role of antibiotics is to kill or inhibit the growth of bacteria, thus treating infections. Vaccines work by training the immune system to recognize and combat pathogens, either viruses or bacteria.
Antibiotics are used when a bacterial infection is present or suspected. Vaccines are administered as a preventive measure, often well before any exposure to the disease.
There are various types of antibiotics, each targeting different types of bacteria. Vaccines vary depending on the disease they are designed to prevent, such as measles, polio, or COVID-19.
The development of new antibiotics is crucial in the fight against antibiotic-resistant bacteria. Vaccine research focuses on developing effective immunization against emerging and existing diseases.
