Vaccines Vaccines. A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. vaccine is a biological preparation that improves immunity to a particular disease.

Attenuated vaccine An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or live). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by killing the virus (inactivated vaccine).

Vaccine Vaccines are complex mixtures of biological compounds, and unlike the case of drugs, there are no true generic vaccines. The vaccine produced by a new facility must undergo complete clinical testing for safety and efficacy similar to that undergone by that produced by the original manufacturer.

What is the flu (influenza)? The flu shot is an inactivated vaccine (containing killed virus) that's given with a needle, usually in the arm. This season's vaccine protects against the three influenza viruses that research indicates will be most common during the season. This includes an influenza A (H1N1) virus, an influenza A (H3N2) virus, and an influenza B virus. The vaccine takes effect approximately two weeks after it has been administered as antibodies (substances in the blood that protect against infection) accumulate and provide protection against influenza.

Immunization Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine.Vaccines stimulate the body’s own immune system to protect the person against subsequent infection or disease.Immunization is a proven tool for controlling and eliminating life-threatening infectious diseases and is estimated to avert between 2 and 3 million deaths each year.accines stimulate the body’s own immune system to protect the person against subsequent infection or disease.

Antiviral drug Vaccines bolster the body's immune system to better attack viruses in the complete particle stage, outside of the organism's cells. They traditionally consist of an attenuated (a live weakened) or inactivated (killed) version of the virus.

IPV a suspension of attenuated or killed microorganisms (viruses, bacteria, or rickettsiae), administered for prevention, amelioration, or treatment of infectious diseases. anthrax vaccine a cell-free protein extract of cultures of Bacillus anthracis, used for immunization against anthrax.alled also Salk vaccine. poliovirus vaccine live oral (OPV) an oral vaccine against poliomyelitis consisting of three types of live, attenuated polioviruses. It is given orally, often on a sugar cube, and so is convenient for administration to children and large groups of people.

Vaccination Another word used for using vaccines is immunization. These words mean things that are a little different. Vaccination is when a person is given something to make the immune system learn to fight an infectious disease. Immunization is when a persons immune system learns to fight an infection. Immunization can happen from vaccination.

How Vaccines Work There are two main groups of vaccines: live-attenuated vaccines and inactivated vaccines. Live-attenuated vaccines: Live-attenuated basically means alive, but very weak. These vaccines are made when the virus is weakened to such a level that they reproduce only about 20 times in the body.

- Understanding the difference between vaccines, vaccinations, and immunizations can be tricky. Below is an easy guide that explains how these terms are used: A vaccine is a product that produces immunity from a disease and can be administered through needle injections, by mouth, or by aerosol. A vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism.

Vaccine A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.he terms vaccine and vaccination are derived from Variolae vaccinae (smallpox of the cow), the term devised by Edward Jenner to denote cowpox.

Comments: Antibiotics vs Vaccines Antibiotics versus Vaccines comparison chart; Antibiotics Vaccines; Definition: Antibiotics are small molecules or compounds that are effective in treating infections caused by organisms such as bacteria, fungi and protozoa. Vaccines are dead or inactivated organisms or compounds that are used to provide immunity to a particular infection or disease. Types

What are vaccines? A vaccine is a biological preparation that establishes or improves immunity to a particular disease. Vaccines can prevent or ameliorate the effects of infection by a pathogen. They typically contain one or more adjuvants which are used to boost the immune system. vaccine is made from dead or weakened microbes, or parts (e.g. surface proteins of a virus) thereof. Once it enters the body, the immune system develops antibodies to it. In the case of exposure to the microbe in the future, antibodies will then fight off/destroy that microbe to prevent disease.

Vaccination Smallpox was most likely the first disease people tried to prevent by inoculating themselves and was the first disease for which a vaccine was produced. The smallpox vaccine was discovered in 1796 by the British physician Edward Jenner, although at least six people had used the same principles years earlier.

Vaccine Timeline The Global Programme for Vaccines and Immunization was created, merging two WHO programs -- the Expanded Programme for Immunization and the former Programme for Vaccine Development, and adding a new unit for Vaccine Supply and Quality.

Attenuated vaccine A attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or live). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by killing the virus (inactivated vaccine).xamples of live (example attenuated) vaccines include: 1  Viral: measles vaccine, mumps vaccine, rubella vaccine, Live attenuated influenza vaccine (the seasonal flu nasal spray and the 2009 H1N1 flu nasal spray), chicken pox vaccine, oral polio vaccine (Sabin), rotavirus vaccine, and yellow fever vaccine.

- Live attenuated vaccines. Live vaccines are derived from “wild,” or disease-causing, virus or bacteria. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. For example, the measles vaccine used today was isolated from a child with measles disease in 1954.ypes of vaccines. The way in which the body responds to a vaccine depends on the type of vaccine being administered. There are several different types of vaccine available and with new technology there will be further additions.

- Meaning matter used in vaccination, the English word vaccine derived in 1846 from the Latin word vaccina, the feminine form of vaccinus, meaning pertaining to a cow.t is attested in the English language in 1846, deriving from the Latin vaccina, meaning pertaining to a cow. Vaccination was coined in 1803 by British physician Edward Jenner (1749-1823) to describe the method of injecting people with the cowpox virus in order to prevent smallpox.

Vaccines: Definition and Types of Vaccines Vaccination and immunisation are two different processes. Vaccination only refers to the administration of a vaccine or toxoid, while immunisation is the process by which the body produces antibodies against the vaccine preventable diseases through administration of spe­cific vaccines. These are used to protect us and our domestic animals against viral and bacterial diseases.

Vaccine The terms vaccine and vaccination are derived from Variolae vaccinae (smallpox of the cow), the term devised by Edward Jenner to denote cowpox.accination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world.

2. What is in a vaccine? Vaccines contain antigens and adjuvants. Vaccines generally have two major types of ingredients, antigens and adjuvants. Antigens are designed to cause the immune system to produce antibodies and/or T-cells against a specific pathogen or its toxin. Adjuvants amplify immune responses more generally.
