Correct Option: D
Explanation:

DPT (also DTP and DTwP) refers to a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus. The vaccine components include diphtheria and tetanus toxoids and killed whole cells of the organism that causes pertussis (wP).

  1. Diphtheria, pneumonia and typhoid

  2. Diphtheria, whooping cough and tetanus

  3. Diarrhoea, pneumonia and tuberculosis

  4. Diphtheria, whooping cough and typhoid

  2. Whooping cough and Tetanus

  3. Whooping cough and Tuberculosis

  4. Polio and Tuberculosis


Correct Option: B

In vaccination

  1. Globular proteins with live disease causing germ is injected

  2. A weakened or dead disease causing germ is administered in small doses

  3. General and local anaesthetics are applied to the patient

  4. Affected part of the human body is amputed


Correct Option: B
Explanation:
Vaccines cause the body to build immunity against infectious diseases without causing the actual disease. Vaccines can be made by weakened or dead disease causing microorganisms like bacteria or virus. The administration of small dose of vaccine causes the formation antibodies which provides immunity. 
Therefore, the correct answer is option B.

The vaccines contains:


a) Derivatives of microbes
b) Dead or weakened microbes
c) Products of microbes

  1. a, b

  2. b, c

  3. c, d

  4. All of the above


Correct Option: D
Explanation:

Vaccines are suspensions of killed or weakened microbes or products or derivatives of micro organisms. A vaccine produces immunity to a disease by stimulating the production of antibodies.
