Question

Second generation vaccines are prepared by recombinant DNA technology. Which out of the following are the examples of such vaccines?

• A. Hepatitis B virus vaccine
• B. Herpes virus vaccine
• C. Salk's polio vaccine
• D. Both (A) and (B)

Answer 1

Answer: (D)

Both (A) and (B)

Second generation vaccines are the vaccines which are prepared by recombinant DNA technique/ genetic engineering, e.g., hepatitis B virus vaccine, herpes virus vaccine and pneumonia vaccine. The yeast-derived recombinant hepatitis B virus vaccine is the first commercially available human vaccine produced by the genetic engineering technology. Hepatitis B vaccine is produced from transgenic yeast by recombinant DNA technology.

So, the correct answer is 'Both (A) and (B)'.
