Recombinant vaccines are also referred to as:
Recombinant vaccines are also referred to as:
Show Hint
Vaccine generations:
1st: whole pathogen (live/attenuated).
2nd: subunit (purified antigens).
3rd: recombinant (DNA/RNA technology).
1st: whole pathogen (live/attenuated).
2nd: subunit (purified antigens).
3rd: recombinant (DNA/RNA technology).
Updated On: Aug 18, 2026
- Third generation vaccines
- First-generation vaccines
- Second generation vaccines
- Conventional attenuated vaccines
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Vaccines are classified into generations.
Each generation represents a technological advancement.
Step 2: Key Formula or Approach:
No specific formula.
Need to know vaccine generations.
Step 3: Detailed Explanation:
Recombinant vaccines are third generation vaccines.
They are produced using recombinant DNA technology.
First generation: whole pathogen vaccines.
Second generation: subunit vaccines.
Third generation: recombinant vaccines.
Thus, recombinant vaccines are third generation vaccines.
Step 4: Final Answer:
Recombinant vaccines are third generation vaccines.
Hence, the correct option is (A).
