The First Use of the Global Oral Cholera Vaccine Emergency Stockpile: Lessons from South Sudan

Abstract

Andrew Azman and colleagues describe their experience of deploying >250,000 doses of oral cholera vaccine in South Sudan in 2014

Fig 1. Timeline of key vaccination events in South Sudan in 2014.

The dots on the timeline represent key vaccination-related events throughout the country. Labels are shown for a selection of events, with the complete timeline shown in S1 Fig. Colors represent different phases of the vaccination campaigns, with red representing planning events, yellow representing logistical activities leading up to the vaccine deployment, and green representing vaccination deployment activities. The epidemic curve is shown as grey vertical bars above.

Fig 2. Epidemic curves of suspected cholera cases in key vaccinated (green) and unvaccinated areas (blue).

Panels show the daily incidence rate of suspected cholera cases in the Juba community (A), the Juba PoC camps (B–C), Wau Shilluk camp (D), and Malakal PoC camp (E). Note that panels A–C have a break in the y-axis, as they had a much smaller incidence rate.

Fig 3. Illustration of the county-level attack rates in the 2014 cholera epidemic with respect to the vaccination locations (orange dots).

Grey areas represent counties with no suspected cholera cases.
