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?
C.Both 1 and 2
D.Neither 1 nor 2
A.1 only
B.2 only
Correct Answer: Option C
Recombinant vector vaccines utilize genetic engineering to introduce a pathogen's genes into a harmless virus or bacteria (the vector).
These vectors then produce antigens within the body, triggering an immune response.
Bacteria and viruses are indeed used as vectors to deliver the genetic material.
Statement 1 is correct: Recombinant vector vaccines rely on genetic engineering.
Statement 2 is correct: Bacteria and viruses serve as vectors in this type of vaccine.
Hence, both statements are correct.
