Question

Vaccines produced through genetic engineering are safe as

• A. They contain antigen only from coat of pathogen
• B. They are least active form of virus
• C. They are attenuated form of pathogen
• D. All of the above

Answer 1

The correct option is A They contain antigen only from coat of pathogen

Genetic engineering, also called genetic modification or genetic manipulation is the direct manipulation of an organism's genes using biotechnology. The vaccines produced through genetic engineering are considered as safe because the antigen is taken from the coat of pathogen. Conventional vaccines contain the whole unit of attenuated or killed pathogen.

So, the correct answer is 'They contain antigen only from the coat of pathogen'.
