With reference to recent developments regarding ‘Recombinant Vector Vaccines’, consider the following statements:
- Genetic engineering is applied in the development of these vaccines.
- Bacteria and viruses are used as vectors.
Which of the statements given above is/are correct?
[UPSC Civil Services Exam – 2021 Prelims]
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Recombinant Vector Vaccines:
- They are genetically modified and involve the use of genetic engineering to mimic the actual virus for which the vaccine is being produced. Hence, statement 1 is correct.
- Recombinant vector vaccines are live replicating viruses that are engineered to carry extra genes derived from a pathogen—and these extra genes produce proteins against which we want to generate immunity. Hence, statement 2 is correct.
