What was the outcome of the Rabies control vaccine campaign in Namibia?

• A. Reduction in rabies cases, improving animal welfare and human safety.
• B. Increase in rabies cases.
• C. No change.
• D. Cure for all diseases.

Answer: (A)

Vaccination campaigns reduce disease by interrupting transmission when a large portion of the population becomes immune, so the virus has fewer hosts to spread to. In Namibia, the rabies control vaccine campaign lowered rabies cases in animals and reduced human exposure, which directly improves animal welfare and human safety. This outcome reflects the fundamental effect of vaccination: fewer infections and less suffering for animals, plus fewer risks to people who might be bitten. The other options don’t fit this effect: an increase in cases would indicate the campaign failed to stop transmission; no change would mean no impact; a cure for all diseases is not achievable by a single rabies vaccination effort.
