With reference to recent developments regarding ‘Recombinant Vector Vaccine’, consider the following statements: 1. Genetic engineering is applied in the d

1. A. 1 only
2. B. 2 only
3. C. Both 1 and 2
4. D. Neither 1 nor 2

Answer: C

Explanation

The recombinant subunit vaccine causes the immune response of the human body by directly injecting the subunit of the pathogen into the body. This method is generally of low immunogenicity and can only induce the humoral immune response of the human body. Therefore, to simultaneously induce the humoral and cellular immune processes of the human body and improve the immunogenicity of vaccines, several technical platforms have been developed to directly produce antigen proteins in the human body. The recombinant virus vector vaccine is one of the important emerging technologies. 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 1 is correct. It exposes the body to proteins made by a virus or bacteria, are often made by using weakened or inactive versions of that virus or bacteria. Hence statement 2 is correct.
