Which factor contributed to Uruguay shifting from depopulation to vaccination?

• A. Strong resistance from local farmers
• B. Disease had spread
• C. Both strong resistance from local farmers and disease had spread
• D. Depopulation was never considered

Answer: (C)

The decision to shift to vaccination comes from a mix of how the disease behaves and how people respond to drastic control methods. If a disease is spreading, there’s strong pressure to act quickly to protect livestock and livelihoods, and vaccination offers a proactive way to build immunity without wiping out animals. At the same time, if local farmers resist depopulation (culling) because it threatens their livelihoods, a non-destructive approach like vaccination becomes more acceptable and feasible. In Uruguay’s case, both pressures were at play: the disease was spreading, and there was significant resistance to depopulation. That combination makes vaccination the practical and acceptable route, explaining why both factors contributed to the shift.
