Gabon
The Gabon Ministry of Health has recently undertaken the EYE Strategy's yellow fever immunity gap analysis. The newly-developed tool seeks to identify priority districts and provide estimates of unprotected populations. These data will then inform future vaccination activities planned by the country.
Immunity gap analyses have also been conducted in Cameroon and Guinea.
Reactive Vaccination Campaigns (RVCs)
All RVCs are approved by the International Coordinating Group on Vaccine Provision (ICG) and supported by Gavi, the Vaccine Alliance.
Central African Republic
An RVC is planned for early 2024 in the following districts: Bossembélé, Berbérati and Bambari. This campaign aims to protect over 435,000 people against yellow fever. This is likely to include vulnerable populations in hard-to-reach places and high-risk workers, such as those working in forests and mines.
Guinea
After confirmation of one confirmed case of yellow fever, the Guinea Ministry of Health implemented an RVC in the district of Dinguiraye to protect 5000 people against yellow fever. Further vaccination activities are planned for 2024.
Preventive mass vaccination campaigns (PMVCs)
Chad
Chad is implementing a yellow fever PMVC in the first part of 2024. The campaign will cover 151 health districts in 23 provinces, which will target around 17 million people for protection. The campaign will be implemented in two phases in February and May 2024.
In February, the campaign will be implemented in the following provinces and integrated integrated with measles vaccinations: Barh El Gazal, Ennedi Est, Logone Oriental, Hadjer Lamis, Kanem, Lac, Tibesti, Sila, Wadi Fira, Ouadai and N'djamena.
In May, the following provinces will be targeted with yellow fever vaccine only: Moyen Chari, Tandjile, Batha, Borkou, Mayo Kebbi East, Guera de l'Ennedi Ouest, Mayo Kebbi Ouest, Logone Occidental, Salamat and Chari Baguirmi.
The Democratic Republic of the Congo (DRC)
Yellow fever PMVCs in Kwilu and Mai Ndombe are due to be implemented in December 2023, and will be integrated with measles round 1. Dates for the implementation of campaigns in Kongo Central and Kwango are yet to be confirmed. In total, these campaigns seek to target almost 12 million people for protection against yellow fever.
Some districts in Kongo Central, Kwango, and Lualaba completed an RVC during the Angola outbreak in 2016. Immunization gaps in these provinces are still being investigated.
Yellow fever vaccination campaigns in the two provinces of Ituri and Nord Kivu are planned for 2024.
