MARKER VACCINES Meaning and
Definition
-
Marker vaccines are a type of vaccine that utilize specific markers or indicators to identify whether an animal or individual has been previously vaccinated for a particular disease. These markers, often proteins or antigens, are placed within the vaccine to trigger an immune response that will produce specific antibodies. The presence of these antibodies serves as evidence that an individual has been vaccinated against the disease of interest.
Marker vaccines have various applications, particularly in veterinary medicine and livestock farming. They are used to differentiate vaccinated animals (DIVA) from those that are infected or unvaccinated, aiding in the control and eradication of infectious diseases. By identifying vaccinated animals, marker vaccines allow for more precise monitoring of disease occurrence and prevention strategies, facilitating targeted surveillance and control efforts.
In addition to DIVA applications, marker vaccines can also play a critical role in disease surveillance programs. These vaccines enable the identification of vaccinated individuals during outbreak investigations or epidemiological studies, allowing public health authorities to assess the extent of vaccination coverage and better understand disease dynamics in a given population.
Marker vaccines have proven invaluable in controlling and managing various diseases, such as foot-and-mouth disease, avian influenza, and bovine viral diarrhea. Their use helps to minimize the economic and social impacts of outbreaks, as well as foster trust in vaccination programs by offering accurate means of identification and disease monitoring.

Etymology of MARKER VACCINES
The term "Marker vaccines" does not have a specific etymology as it is a combination of two words: "Marker" and "Vaccines". Each word individually has its own origin:
1. Marker: The word "marker" originates from the late 15th century and is derived from the Middle French word "marqueur" or "marquer", meaning "to mark". It developed from the Latin word "marcari" meaning "to mark, stake out". In the context of vaccines, a marker refers to a substance or characteristic used to detect or identify the presence of a particular pathogen or vaccine within an individual.
2. Vaccines: The term "vaccine" dates back to the late 18th century and is derived from the Latin word "vaccinus", meaning "of or from cows".
