- 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?
Answer
Both 1 and 2
Statement 1: Correct. Recombinant vector vaccines are made using genetic engineering, where a gene coding for an antigen is inserted into another organism/vector.
