Republic of the Congo to vaccinate more than 4 million people against yellow fever

  • The preventive mass vaccination campaign will target nearly the entire population, ranging from 9 months to 60 years old in 11 departments in Congo.

  • Congo is located in the yellow fever belt in Africa, putting it at risk of deadly oubtreaks.

  • The campaign is supported by Gavi, the Vaccine Alliance, UNICEF, WHO and partners.

Geneva, 05 August 2022 – The Republic of the Congo has launched a preventive mass vaccination campaign that aims to vaccinate more than 93% of the population against yellow fever. The campaign, which begins today, will target over 4 million people in 11 out of the 12 departments across the country. Congo has set a goal of achieving national coverage of more than 95%.

More than 13,800 health professionals are mobilised through the Government of Congo for the seven-day campaign, which is supported by Gavi, the Vaccine Alliance, UNICEF, WHO and partners. A successful campaign will help prevent outbreaks of yellow fever, and enable strengthened surveillance systems that can search for and quickly identify cases. Pointe Noire is the only department that will not be involved in this mass campaign, as it previously benefitted from a reactive campaign, achieving 93% coverage.

“Yellow fever, which is endemic across Western and Central Africa, claims the lives of up to 60,000 Africans every year – lives that can be saved with a highly effective vaccine. We are proud to work with the Government of Congo and partners on this preventive mass vaccination campaign, which will ensure the people of Congo are protected against this deadly disease and will reduce the risk of deadly outbreaks from emerging,” said Thabani Maphosa, Gavi’s Managing Director of Country Programmes.

Yellow fever vaccination coverage in the country has increased since the introduction of the vaccine into the routine immunisation schedule in 2004, moving from 54% coverage in 2005 to 80% in 2015. However, the risk of an epidemic remains high and can only be reduced if the majority of the total population is immunised. According to the latest WHO/UNICEF Estimates of National Immunization Coverage (WUENIC) data, while the percentage of children in the Republic of the Congo who received three doses of diphtheria, tetanus and pertussis-containing vaccine (DTP3) rose to 77% in 2021 from 73 % in 2020, and coverage of the first dose of measles-containing vaccine (MCV1) remained at 68%, Congo experienced a consistent 2% downward trend in yellow fever coverage during the last two years of the unprecedented COVID-19 pandemic (from 2019–2021).

“The main tools in the fight against yellow fever are preventive vaccination, development of a global vaccine stockpile for response and support for greater preparedness in the countries most at risk. The Government of Congo, working with partners, will make every effort to achieve the objectives of the campaign to eliminate ongoing epidemics in the country,” said Dr Edouard Ndinga, Head of the Immunization and Vaccine Preventable Diseases (IVD) cluster at WHO Congo.

Yellow fever is an acute viral haemorrhagic disease transmitted by infected mosquitoes, which can be deadly, but is prevented by an extremely effective vaccine. In recent years, deadly outbreaks of yellow fever in Congo (and neighbouring Angola and the Democratic Republic of the Congo) have put the country at risk and on high alert of another possible outbreak.

“This mass preventative campaign in Congo is part of a comprehensive strategy to eliminate yellow fever epidemics (EYE) globally by 2026. Gavi, UNICEF, WHO and more than 50 partners are supporting the Government of Congo and 39 other high-risk countries to assess epidemic risk, roll out vaccination campaigns, engage with communities and deliver other response activities, including surveillance, logistics and supply, and laboratory diagnosis. The campaign will be integrated with a measles-rubella campaign led by the Government of Congo and supported by the World Bank to respond to an ongoing measles outbreak,” added Dr Chantal Umutoni, UNICEF Representative in Congo.

About Gavi, the Vaccine Alliance

Gavi, the Vaccine Alliance is a public-private partnership that helps vaccinate half the world’s children against some of the world’s deadliest diseases. Since its inception in 2000, Gavi has helped to immunise a whole generation – over 981 million children – and prevented more than 15 million future deaths, helping to halve child mortality in 73 lower-income countries. Gavi also plays a key role in improving global health security by supporting health systems as well as funding global stockpiles for Ebola, cholera, meningococcal and yellow fever vaccines. After two decades of progress, Gavi is now focused on protecting the next generation, above all the zero-dose children who have not received even a single vaccine shot. The Vaccine Alliance employs innovative finance and the latest technology – from drones to biometrics – to save millions more lives, prevent outbreaks before they can spread and help countries on the road to self-sufficiency.
