Description
Louise C Ivers and co-authors present a 2026 case-control study of oral cholera vaccine durability in rural Haiti. The vaccine Euvichol was delivered in a campaign in 2017. How well it still protected five years later had not been measured.
The study compared patients with confirmed cholera against matched community controls in the Mirebalais area. Vaccination history came from participant reports. A far smaller share of cases than controls reported vaccination. Adjusted analysis found strong protection remaining at five years after at least one dose. The authors say the result matters for planning booster timing in outbreak-prone settings. Long protection also strengthens the case for preventive campaigns ahead of outbreaks.
