Edward Jenner was an English physician and scientist who was the pioneer of smallpox vaccine, the world's first vaccine. He is often called the father of immunology. Heredity refers to the transfer of biological characteristics from a parent organism to offspring. DNA in the form of large molecules known as chromosomes which is the carrier of genetic instructions for the development and functioning of living organisms. Hydras generally reproduce asexually. They do this through budding.
Vaccine developed by Pasteur was against

Chicken pox
-
Anthrax
-
Rabies
-
Both B and C

-
Typhoid
-
Chickenpox
-

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.
