An effective vaccine was developed.
Explanation: A safe, effective smallpox vaccine plus a coordinated global vaccination and surveillance (ring vaccination) campaign by WHO eliminated human cases. Smallpox had no animal reservoir and produced obvious symptoms, which made eradication feasible. The other choices (exercise, genetic testing, antibacterial products) would not prevent or eliminate a viral disease like smallpox.
