Question

Which of the following disease has its vaccine in inactivated form?

• A. Tuberculosis
• B. Typhoid
• C. Influenza
• D. Mumps

Hint:

BCG and MMR are live attenuated vaccines, while influenza vaccine is commonly available as an inactivated vaccine.

Answer 1

The Correct Option is C

Concept:
Vaccines may be live attenuated, inactivated, toxoid, subunit, recombinant, or conjugate vaccines. An inactivated vaccine contains pathogens that have been killed or chemically inactivated so that they cannot reproduce.

Step 1: Understand inactivated vaccine.
Inactivated vaccines contain killed forms of the pathogen. Since the organism is dead, it cannot cause disease, but it can still stimulate the immune system.

Step 2: Check tuberculosis vaccine.
Tuberculosis vaccine is BCG. BCG is a live attenuated vaccine, not an inactivated vaccine. \[ \text{Tuberculosis} \rightarrow \text{Live attenuated vaccine} \]

Step 3: Check mumps vaccine.
Mumps vaccine is usually given as part of MMR vaccine. It is also a live attenuated vaccine. \[ \text{Mumps} \rightarrow \text{Live attenuated vaccine} \]

Step 4: Check influenza vaccine.
Influenza has commonly used inactivated vaccines. Inactivated influenza vaccines are widely used to provide protection against seasonal flu. \[ \text{Influenza} \rightarrow \text{Inactivated vaccine} \]

Step 5: Final conclusion.
Among the given options, influenza is the disease whose vaccine is commonly available in inactivated form. \[ \therefore \text{Correct Answer is (C)} \]
