Question:
For one of the following, recombinant vaccine is available in the market
For one of the following, recombinant vaccine is available in the market
Show Hint
Recombinant vaccines like the Hepatitis B vaccine have revolutionized immunization by using genetic engineering to produce safe and effective vaccines.
Updated On: May 6, 2025
- Hepatitis B virus
- Polio virus
- Rubella virus
- Dengue virus
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Recombinant vaccines are made by inserting the genetic material of a virus or bacterium into a different organism (like yeast or bacteria) to produce the antigen of the pathogen. The recombinant vaccine for \textit{Hepatitis B} is one of the most widely used examples of this technology. The vaccine contains the surface antigen (HBsAg) produced in yeast cells after being genetically engineered.
(1) Why Other Options Are Incorrect:
- Polio virus: The polio vaccine is not a recombinant vaccine but is produced using inactivated or attenuated forms of the virus.
- Rubella virus: The rubella vaccine is also not a recombinant vaccine but uses live attenuated virus for vaccination.
- Dengue virus: Currently, no recombinant vaccine is available for dengue; vaccines are produced using other methods.
Conclusion: The recombinant vaccine available for public use is for Hepatitis B virus.

- Immunity in our body is of two types: (i) Innate immunity and (ii) acquired immunity. Innate immunity is a non-specific defence mechanism, whereas acquired immunity is pathogen-specific; it is called specific immunity too. Acquired immunity is characterised by memory. Antibodies are specific to antigens and there are different types of antibodies produced in our body: they are IgA, IgE, IgG, IgC, and IgM. It shows primary response when it encounters the pathogen for the first time and secondary response during the subsequent encounters with the same antigen/pathogen. Name the two types of specialised cells which carry out the primary and secondary immune response.
