Multiple choice vaccines antibody production and vaccination immunity animal physiology biology

Vaccine developed by Pasteur was against

  1. Chicken pox

  2. Anthrax

  3. Rabies

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
During the mid- to late 19th century Pasteur demonstrated that microorganisms cause disease and discovered how to make vaccines from weakened, or attenuated, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.

So, the correct answer is 'Both B and C'.

Which of the following diseases has been eradicated by vaccination?

  1. Typhoid

  2. Chickenpox

  3. Smallpox

  4. Kala-azar

C Correct answer
Explanation

The smallpox vaccine is made from the weekend virus called Vaccinia, which is another smallpox-type virus that cannot cause infections. This vaccine helps the body develop immunity to smallpox and thus successfully eradicate smallpox from the human population.

Who discovered vaccination against small pox?

  1. Jenner

  2. Pasteur

  3. Lister

  4. Mayer
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Edward Jenner found that vaccination with cowpox can protect individuals from smallpox. Edward Jenner was well known for his contribution to immunization and eradication of smallpox. Jenner's work was widely regarded as the foundation of immunology and known as the father of immunology. The smallpox vaccine was the only way to prevent smallpox. The vaccine was made from a virus either weakened or attenuated, which was introduced into the blood. This helps in building antibodies against the smallpox virus in the body. Smallpox was eradicated by this vaccination program, starting in 1967. 
Thus, the correct answer is option 'Jenner'.

Vaccination against small pox means the introduction of  

  1. Leucocytes obtained from an animal

  2. Antibodies produced in other animals

  3. Antibodies

  4. Actual weakened germs or attenuated small pox virus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The smallpox vaccine is the only way to prevent smallpox. The vaccine is made from a virus either weakened or attenuated (has lost its ability to cause the disease), which is introduced into the blood. This helps in building the antibodies against the smallpox virus in the body. Smallpox was eradicated by this vaccination program, starting in 1967.

Vaccine is example of ___________ immunity.

  1. Natural acquired active immunity

  2. Natural acquired passive immunity

  3. Artificial acquired active immunity

  4. Artificial acquired passive immunity

C Correct answer
Explanation

Vaccines contain dead or alive but attenuated pathogens or toxoids consisting of microbial components. Vaccines is introduces into the body to stimulate the formation of antibodies by the immune system.

Jenner prepared vaccine for small pox virus by employing

  1. Attenuated small pox virus

  2. Small doses of small pox virus

  3. Attenuated cow's pox virus

  4. Large doses of small pox virus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Edward Jenner administered the world’s first vaccination as a preventive treatment for smallpox. He took fluid from a cowpox blister, attenuated the cowpox virus and introduced it into the skin of James Phipps, an eight-year-old boy who is suffering from smallpox. A single blister rose up on the spot, but James soon recovered.

So, the correct answer is 'Attenuated cow's pox virus'.

The technique of preparing vaccine from attenuated pathogen was discovered by 

  1. Edward Jenner (1796)

  2. Robert Koch (1876)

  3. Louis Pasteur (1879)

  4. Von Behring (1891)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (live). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. The technique of preparing vaccine from attenuated pathogen was first discovered by Louis Pasteur in 1879 against anthrax and rabies.

So, the correct answer is 'Louis Pasteur (1879)'.

Which of the following established the scientific basis of vaccination?

  1. Louis Pasteur

  2. John Mendel

  3. Cesar Milstein

  4. George Kohler

A Correct answer
Explanation
  • Louis Pasteur (1822-1895) demonstrated that microorganisms cause both fermentation and disease, which support the germ theory of disease. He developed the earliest vaccines against anthrax.

The process of vaccination was discovered by

  1. Edward Jenner (1796)

  2. Robert Koch (1876)

  3. Louis Pasteur (1879)

  4. Von Behring (1891)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen.
  •  It 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 elimination of diseases such as polio, measles, and tetanus from much of the world.
  •  Edward Jenner discovered the process of vaccination in 1796 by introducing material from cowpox vesicle.
So, the correct answer is 'Edward Jenner (1796)'.
