  1. Antibodies

  2. Antigen

  3. Antibiotics

  4. None of the above

Show answer
Correct Option: B
Explanation:

Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used - an inactivated poliovirus (antigen) given by injection and a weakened poliovirus (antigen) given by mouth. The inactivated polio vaccines are very safe. Mild redness or pain may occur at the site of injection. Oral polio vaccines cause vaccine-associated paralytic poliomyelitis.

So, the correct answer is 'Antigen'.

DPT vaccine acts against

  1. Diphtheria, Wooping cough, Tetanus

  2. Diarrhoea, Polio, Tetanus

  3. Diphtheria, Polio, Tetanus

  4. Diarrhoea, Whooping cough, Tetanus

Show answer
Correct Option: A
Explanation:

DPT (also DTP and DTwP) is 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 bacterium that causes pertussis (wP). So, the correct option is "A" (Diphtheria, Wooping cough, Tetanus).

  1. First generation vaccine

  2. Interferon

  3. Second generation vaccine

  4. Third gereration vaccine

Show answer
Correct Option: C
Explanation:

Second generation vaccines were developed to reduce the risks from live vaccines. These are subunit vaccines, consisting of defined protein antigen like tetanus or diphtheria toxoid or recombinant protein components like hepatitis B surface antigen.
Therefore, the correct answer is option C.

BCG Stand for

  1. Bacterial cell genome

  2. Bacillus Calmette Guerin

  3. Bacteria culture growth

  4. None of the above

Show answer
Correct Option: B
Explanation:

BCG stands for Bacillus Calmette Guerin, a vaccine given for protection against tuberculosis which is an airborne disease, caused by Mycobacterium tuberculosis.  

Thus, the correct answer is option B. 

Oral vaccine is given for

  1. Polio

  2. Smallpox

  3. Diphtheria

  4. Tetanus

Show answer
Correct Option: A
Explanation:

The oral polio vaccine (OPV) was developed in 1961 by Albert Sabin. OPV consists of a mixture of live, attenuated (weakened) polio virus strains of all three polio virus types. Rotavirus liquid vaccines are also given by mouth (orally) to infants.

The vaccine triple antigen is given to children to protect them against

  1. Tetanus, Diphtheria and Whooping cough

  2. Polio, Tuberculosis and Diphtheria

  3. Diphtheria, Polio and Tetanus

  4. None of the above

Show answer
Correct Option: A
Explanation:

Triple antigen vaccine is a combination of diphtheria, tetanus and pertussis (or whooping cough). The vaccine stimulates the production of antibodies to immunize the body against the causative agents of the three viruses.

DTP vaccine is given to infants to immunize them against

  1. Diptheria, pneumonia and typhoid

  2. Diphtheria, whooping cough and tetanus

  3. Diarrhoea, pneumonia and tuberculosis

  4. Diptheria, whooping cough and typhoid

Show answer
Correct Option: B
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). 

BCG vaccine contains

  1. Live but attenuated bacteria

  2. Killed bacteria

  3. Toxoids against TB-bacteria

  4. Antibodies against bacteria

Show answer
Correct Option: A
Explanation:

The BCG vaccine contains a live but weakened form of a type of bacteria called Mycobacterium bovis which causes tuberculosis (TB) in cattle. The bacteria are altered so that they do not cause a TB infection, but stimulate the immune system to make resistant to the disease. The vaccine is known as BCG because a strain of the bacterium known as Bacillus Calmette-Guerin is used. 

DPT is administered to prevent

  4. All of the above

Show answer
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).
