Questions Related to immunity
Vaccine developed by Pasteur was against
-
Chicken pox
-
Anthrax
-
Rabies
-
Both B and C
Which of the following diseases has been eradicated by vaccination?
-
Typhoid
-
Chickenpox
-
Smallpox
-
Kala-azar
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?
-
Jenner
-
Pasteur
-
Lister
-
Mayer
Vaccination against small pox means the introduction of
-
Leucocytes obtained from an animal
-
Antibodies produced in other animals
-
Antibodies
-
Actual weakened germs or attenuated small pox virus
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.
The methods of administering vaccines _________
-
Inoculation
-
Orally
-
Both A and B
-
None of these
The methods of administering vaccines is by inoculation, but some are given orally. A vaccine produces immunity to a disease by stimulating the production of antibodies.
Vaccine is example of ___________ immunity.
-
Natural acquired active immunity
-
Natural acquired passive immunity
-
Artificial acquired active immunity
-
Artificial acquired passive immunity
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
-
Attenuated small pox virus
-
Small doses of small pox virus
-
Attenuated cow's pox virus
-
Large doses of small pox virus
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.
The technique of preparing vaccine from attenuated pathogen was discovered by
-
Edward Jenner (1796)
-
Robert Koch (1876)
-
Louis Pasteur (1879)
-
Von Behring (1891)
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.
Which of the following established the scientific basis of vaccination?
-
Louis Pasteur
-
John Mendel
-
Cesar Milstein
-
George Kohler
- 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
-
Edward Jenner (1796)
-
Robert Koch (1876)
-
Louis Pasteur (1879)
-
Von Behring (1891)
- 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.
