On 09 December 1979, the World Health Organization (WHO) certified the eradication of smallpox, a groundbreaking moment in global health history. This decision followed a meticulous review by an independent global commission, which confirmed that no cases of smallpox had been reported since the last known natural case in Somalia in 1977. The certification marked the culmination of a concerted global vaccination and surveillance campaign launched by WHO in 1967.
The official declaration of smallpox eradication was made on 08 May 1980, during the 33rd World Health Assembly. This announcement formalized the achievement, making smallpox the first human disease to be eradicated through deliberate intervention. The eradication effort involved unprecedented international collaboration, with mass immunization, the development of freeze-dried vaccines, and the innovative use of ring vaccination strategies to contain outbreaks.
This dual milestone—certification in December 1979 and the formal declaration in May 1980—remains a symbol of what can be achieved through global unity, scientific innovation, and public health dedication. It also highlights the importance of vigilance in preventing the re-emergence of diseases in a connected world.
