Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Triple Antigen (DPT vaccine) is used to provide immunity against diphtheria, pertussis (whooping cough), and tetanus.

Multiple choice

Which of the following treatments is used for tetanus?

  1. Ascorbic acid

  2. ATS

  3. Chloroquin

  4. BCG
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

ATS stands for Anti-Tetanus Serum, which is used to provide passive immunity against the tetanus toxin. BCG is a vaccine for tuberculosis, and Chloroquin is for malaria.

Multiple choice

BCG vaccine is used against

  1. tuberculosis

  2. leprosy

  3. food poisoning

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

BCG (Bacillus Calmette-Guerin) is a vaccine primarily used to prevent tuberculosis. It is derived from an attenuated strain of Mycobacterium bovis.

Multiple choice

Hepatitis-B vaccine is

  1. first generation vaccine

  2. second generation vaccine

  3. third generation vaccine

  4. fourth generation vaccine
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Hepatitis-B vaccine is considered a second-generation vaccine because it is produced using recombinant DNA technology, specifically by expressing the viral surface antigen in yeast.

Multiple choice

Vaccines are

  1. the same as monoclonal antibodies

  2. treated bacteria or viruses, or one of their proteins

  3. short-lived

  4. MHC proteins
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vaccines function by introducing a harmless form of a pathogen (or its proteins) to the immune system, allowing it to develop memory and immunity without causing the disease.

Multiple choice

Injection of antitoxin or toxoid serum is given to prevent

  1. diphtheria

  2. small pox

  3. chicken pox

  4. chronic headache
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Antitoxins and toxoids are specifically used to provide immunity or neutralize toxins associated with bacterial diseases like diphtheria. Smallpox and chickenpox are viral and typically managed via vaccines, not antitoxins.

Multiple choice

Triple vaccine is administered to a new born child to immunize it against:

  1. Whooping cough, tetanus and measles

  2. Whooping cough, tetanus and diphtheria

  3. Tetanus, Diphtheria, Measles and rubella

  4. Tetanus, diphtheria, small pox and rubella
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The DPT vaccine (Triple Antigen) is administered to infants to provide immunity against Diphtheria, Pertussis (whooping cough), and Tetanus.

Multiple choice

Antigens trigger the production of

  1. microbes

  2. antibodies

  3. antibiotics

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Antigens are foreign substances that the immune system recognizes, triggering the production of specific antibodies to neutralize them.
