Question:
Which vaccine is produced by using genetically modified yeast?
Which vaccine is produced by using genetically modified yeast?
Show Hint
Hepatitis B vaccine is an example of a recombinant vaccine produced using genetically engineered yeast cells to express viral antigens.
Updated On: Jun 19, 2026
- Polio
- BCG
- Hepatitis - B
- Covaxin
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the vaccines.
Hepatitis B vaccine can be produced using recombinant DNA technology, where the gene coding for Hepatitis B surface antigen is inserted into yeast cells. The yeast then produces the antigen, which is used in the vaccine.
Step 2: Analysis of other options.
- Polio vaccine: Produced using inactivated or attenuated virus, not genetically modified yeast.
- BCG vaccine: Made from live attenuated Mycobacterium bovis, not yeast.
- Covaxin: Inactivated whole virion vaccine, not produced using yeast.
Step 3: Conclusion.
The Hepatitis B vaccine is the one produced using genetically modified yeast.
