The study on single-dose cholera vaccine in Zambia evaluates the effectiveness of using a single dose of the oral cholera vaccine (OCV) during a 2016 outbreak in Lusaka. Due to limited vaccine supply, authorities opted for a one-dose emergency campaign instead of the usual two-dose regimen. A matche...d case-control study was conducted to assess vaccine effectiveness, showing 88.9% short-term protection against cholera. The findings suggest that a single-dose approach can be an effective strategy in outbreak settings, especially when vaccine supplies are constrained. However, further research is needed to determine long-term immunity and effectiveness in young children.

The article "The Political Determinants of the Cholera Outbreak in Yemen" examines how the ongoing civil war has contributed to Yemen’s severe cholera outbreak. The 2017 epidemic was des...cribed as the worst in the world, with cholera spreading rapidly due to the collapse of health, water, and sanitation systems.
The analysis shows that Houthi-controlled areas were disproportionately affected, accounting for 77.7% of cases and 80.7% of deaths. The article highlights the role of the Saudi-led coalition in worsening conditions through airstrikes on infrastructure, blockades restricting medical and food supplies, and the overall humanitarian crisis. It criticizes UNICEF for accepting a $67 million donation from Saudi Arabia while the coalition contributed to the crisis.
The article underscores that political actions and conflict have been key factors in the outbreak’s severity, with both warring sides failing to protect civilians.

The article "Effectiveness of one dose of oral cholera vaccine in response to an outbreak: a case-cohort study" investigates whether a single dose of the Shanchol oral cholera vaccine can provide effective protection during an outbreak. Conducted i...n Juba, South Sudan, in 2015, the study involved a case-cohort approach, analyzing vaccination status and disease outcomes.
Findings showed that a single dose was 80.2% effective in preventing medically attended cholera cases, increasing to 87.3% after adjustments for confounding factors. These results suggest that a single-dose strategy can be an effective emergency response, particularly in settings with limited vaccine supply and high mobility of affected populations. The study supports using a single-dose approach during outbreaks when a two-dose regimen is logistically challenging.
