Difference Between Antibiotics and Vaccines
Antibiotics vs. Vaccines
An antibiotic is a compound or a substance that inhibits or kills the growth of bacteria. It belongs to the group of antimicrobial compounds, which is used to treat the infections caused by microorganisms. Antibiotics are from the class one of antimicrobial.
Antimicrobial is a group which also includes anti-parasitic, anti-fungal and anti-viral drugs. These are used to treat infection but are harmless to the host. Antibiotics were named magic bullet drugs which without harming the host kills the bacteria. On the other hand, it is not effective in fungal, viral and non bacterial infections. The bacteria which attacks our immune system, starts reproducing and causes disease. The antibiotic kills the bacteria and eliminates the disease. For example, in an ear infection, bacteria go into the inner ear and the ear starts to inflame or the host experiences pain. One can kill the bacteria and eliminate the pain by taking antibiotics.
Antibiotics are not effective on viruses because viruses are not alive. It is just a piece of RNA or DNA whereas bacteria are living organisms which reproduce rapidly. Antibiotic cannot cure disease like cancer because cancer is neither a bacteria nor a virus.
Vaccine is a preparation that improves the immunity to a particular disease. It contains a little amount of an agent, which resembles microorganisms. This agent enters the body and interacts with the immune system and stimulates it so that it can recognize the microorganism and destroy it. Once it is recognized, the immune system remembers it and destroys these microorganisms in later encounter.
There are many types of vaccines available in the market. Microorganisms are killed by chemical or heat. Vaccines are effective against diseases like cholera, flu, polio, hepatitis A, and plague and bubonic. Some vaccines contain live attenuated virus microorganisms, which have been cultivated under conditions that disable their virulent properties.
Vaccines cannot cure disease like cancer. Vaccines have eradicated many diseases like small pox, rubella, mumps, polio, typhoid and chickenpox which are some common and dangerous diseases for years. The most contagious and deadly disease among all of these are the small pox.
An antibiotic kills bacteria whereas vaccine deals with the virus, and improves the immune system. A vaccine prevents diseases like polio, small pox, chicken pox, etc. which are caused by a virus. An antibiotic heals infection caused by bacteria. Vaccines prevent the virus from infecting again once it is given to a person because it stays in the immune system.
1)Vaccine kills virus while antibiotics kill bacteria.
2)Vaccine is taken once and has permanent effect whereas antibiotics work during the time of disease.
3)Antibiotics are available in different forms like tablets, capsules, drops or ointments. Vaccines can be given orally or through injection.
4)Vaccines are preventive method that is taken before getting infected. Antibiotics are taken after getting infected.
