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

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
Reveal answer Fill a bubble to check yourself
B Correct answer

Which of the following diseases is not treated by inactivated 'Whole Agent Vaccine'?

  1. Hepatitis-A

  2. Bubonic plague

  3. Cholera

  4. Typhoid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • In 1896, heat-killed phenol preserved and acetone killed lyophilized injectable whole cell S. Typhi vaccine was generated. 
  • This inactivated whole-cell vaccine causes local inflammation, pain, systemic fever, malaise and disease-like symptoms.  
  • Thus, the whole cell inactivated vaccine was not considered suitable for public use and in spite of being licensed it is no longer available in the market. 
  • Most commonly used antibiotics for the treatment of typhoid fever are fluoroquinolones such as ciprofloxacin, ofloxacin and pefloxacin and third-generation cephalosporins such as ceftriaxone or cefotaxime. 
  • Hence, Typhoid is not treated by inactivated Whole Agent Vaccine.
  •  So, the correct answer is 'Typhoid'.

Match the type of antigen given in Column I with the example given in Column II of vaccine.

Column I Column II
a. Live attenuated (i) Salk polio vaccine
b. Killed microbes (ii) Tetanus vaccine
c. Toxoid (iii) Hepatitis 'B' vaccine
d. Antigen polypeptides synthesised by genetic engineering (iv) MMR vaccine

  1. a(ii), b(iii), c(i), d(iv)

  2. a(ii), b(i), c(iii), d(iv)

  3. a(iv), b(i), c(ii), d(iii)

  4. a(iv), b(ii), c(i), d(iii)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Matching the vaccine types: Live attenuated corresponds to the MMR vaccine (a-iv), killed microbes corresponds to the Salk polio vaccine (b-i), toxoid corresponds to the Tetanus vaccine (c-ii), and antigen polypeptides synthesized by genetic engineering correspond to the Hepatitis B vaccine (d-iii). This matches option C.
