Question

The word ‘Vaccination’ has been derived from a Latin word which relates to
A. Pig
B. Horse
C. Cow
D. Dog

Answer 1

Hint: Vaccination is the use of vaccines to help the immune system develop protection against disease. Vaccines contain live or killed microorganisms or viruses, or weakened proteins or toxins from the organism. By enhancing the body’s adaptive immunity, they help prevent illness from infectious disease. When a sufficiently large proportion of the population has been vaccinated, herd immunity will be achieved.

Complete answer
Option A Pig: The pig is one of the animals of the genus Sus, in the ungulate family Suidae. Pigs include domestic pigs and their ancestors, the Eurasian wild boar, as well as other species. Porcus is the latin word for pig. It does not have any relation with the word vaccination.
Hence option A is not correct.
Option B Horse: A domesticated one-toed hoofed mammal is known as a horse. Horse belongs to the taxonomic family Equidae, which is one of two extant subspecies of Equus ferus. Equus is the latin word for horse. It does not have any relation with the word vaccination.
Hence option B is not correct.
Option C Cow: Cattle, or cows and bulls, are large domesticated herbivores with hooves. They are a prominent modern member of the subfamily Bovinae, the most common species in the genus Bos, and are generally classified as Bos taurus. Edward Jenner created the word vaccine and comes from the Latin word “vacca”, which means cow.
Hence option C is the correct answer.
Option D Dog: This breed is descended from an extinct ancient wolf, and the modern gray wolf is its closest relative. Dogs were the first species to be domesticated by hunter-gatherers before the development of agriculture. Canis is the latin word for dog and it does not have any relation with the word vaccine.
Hence option D is not correct.

Hence, Option C. Cow is the correct answer
