*Data source: Ministry of Public Health and Population of Haiti (pers. comm., 2021 Jul 20; see also Appendix). NA, not applicable; OCV, oral cholera vaccine. †The proportion of fully vaccinated population was calculated by dividing the number of persons who received the 2nd OCV dose by the population of Haiti. ‡Percentage of the population with residual vaccine immunity was estimated taking into account the number of vaccinated persons, the percentage of fully vaccinated persons, and the published protection duration after a 1-dose and 2-dose regimen (Appendix).
