Question

Mass vaccination is ineffective in which of the following?

• A. Measles
• B. Polio
• C. Tetanus
• D. None

Hint:

Think Pulse Polio, measles catch-up rounds and tetanus toxoid campaigns.

Answer 1

The Correct Option is D

Step 1: The trick here is that the question lists three diseases for which mass vaccination is a real, recommended strategy, so the catch-all option is the one to test.

Step 2: Look at each disease. Polio control relied on Pulse Polio campaigns, the textbook mass-vaccination programme that delivered oral vaccine to all children in a short window. Measles outbreaks are controlled with mass supplementary immunisation rounds because the agent spreads so easily that high uniform coverage is essential.

Step 3: Tetanus prevention also uses mass methods, notably the campaign of giving tetanus toxoid to all women of reproductive age, which is how maternal and neonatal tetanus is eliminated from a region.

Step 4: Because every named disease is in fact addressed by mass vaccination, none of them is an exception. The answer is the option that says so.

\[\boxed{\text{None}}\]
