Vaccine Matching Solution 

Vaccine Classification Breakdown

This question requires matching specific vaccines to their correct classification based on how they are made or work.

• Hepatitis B vaccine: This is a Sub unit vaccine. It uses only specific pieces (antigens) of the virus, like a surface protein, to trigger an immune response.
• Diphtheria vaccine: This is a Toxoid vaccine. It uses an inactivated toxin (toxoid) produced by the bacteria, which the immune system learns to fight without causing the disease.
• Haemophilus influenzae vaccine (Hib): This vaccine, specifically targeting type b, is typically a conjugate vaccine, which is derived from the Polysaccharide capsule of the bacteria linked to a carrier protein.
• Measles vaccine: This is a Live attenuated vaccine. It contains a weakened (attenuated) form of the live virus that can still replicate but does not cause serious illness.

Matching List I with List II

Based on the classifications:

• A. Hepatitis B vaccine matches with 2. Sub unit vaccine
• B. Diphtheria vaccine matches with 3. Toxoid
• C. Haemophilus influenzae vaccine matches with 4. Polysaccharide vaccine
• D. Measles vaccine matches with 1. Live attenuated vaccine

Final Correct Match Code

The correct combination is A/2, B/3, C/4, D/1.

This corresponds to the matching code: A/2 B/3 C/4 D/1.
