Introduction and Rollout of a New Group A Meningococcal Conjugate Vaccine (PsA-TT) in African Meningitis Belt Countries, 2010-2014.

BACKGROUND: A group A meningococcal conjugate vaccine (PsA-TT) was developed specifically for the African "meningitis belt" and was prequalified by the World Health Organization (WHO) in June 2010. The vaccine was first used widely in Burkina Faso, Mali, and Niger in December 2010 with great success. The remaining 23 meningitis belt countries wished to use this new vaccine. METHODS: With the help of African countries, WHO developed a prioritization scheme and used or adapted existing immunization guidelines to mount PsA-TT vaccination campaigns. Vaccine requirements were harmonized with the Serum Institute of India, Ltd. RESULTS: Burkina Faso was the first country to fully immunize its 1- to 29-year-old population in December 2010. Over the next 4 years, vaccine coverage was extended to 217 million Africans living in 15 meningitis belt countries. CONCLUSIONS: The new group A meningococcal conjugate vaccine was well received, with country coverage rates ranging from 85% to 95%. The rollout proceeded smoothly because countries at highest risk were immunized first while attention was paid to geographic contiguity to maximize herd protection. Community participation was exemplary.

Communication Challenges During the Development and Introduction of a New Meningococcal Vaccine in Africa.

BACKGROUND: A new group A meningococcal conjugate vaccine was developed to eliminate deadly meningitis epidemics in sub-Saharan Africa. METHODS: From the outset of the project, advocacy and communication strategies were developed and adjusted as the project evolved in Europe, Africa, India, and the United States. Communications efforts were evidence-based, and involved partnerships with the media and various stakeholders including African ministries of health, the World Health Organization, UNICEF, Gavi, the Centers for Disease Control and Prevention, and Médecins Sans Frontières. RESULTS: The implementation of an integrated communication strategy ensured the active cooperation of stakeholders while providing an organized and defined format for the dissemination of project-related developmental activities and the successful introduction of the vaccine. CONCLUSIONS: Early in the project, a communications strategy that engaged stakeholders and potential supporters was developed. The strategy was implemented and adapted as the project matured. Linked communication proved to be key to the successful wide-scale introduction of the PsA-TT (MenAfriVac) vaccine in Africa.

Update on Elimination of Epidemic Meningitis in the African Region

At the demand of the African ministries of health; a new conjugate vaccine was developed by Serum Institute of India Limited (SIIL) against meningococcal A meningitis; the germ responsible for more than 95 of the meningitis epidemics in Africa; through a partnership between WHO and PATH and; with the financial support from the Bill et Melinda Gates Foundation. The vaccine is being introduced in all the 26 countries of the meningitis belt between 2010 and 2016. So far; 153 million people have been vaccinated in 12 countries. The vaccine is efficacious; no case of meningococcal meningitis A has been identified among vaccinated individuals and in post-campaign carriage studies. The overall number of meningitis cases dropped sharply during epidemic seasons in the countries of the belt. The vaccine will be introduced via routine immunization by the end of 2015

Effectively introducing a new meningococcal A conjugate vaccine in Africa: the Burkina Faso experience.

A new Group A meningococcal (Men A) conjugate vaccine, MenAfriVac™, was prequalified by the World Health Organization (WHO) in June 2010. Because Burkina Faso has repeatedly suffered meningitis epidemics due to Group A Neisseria meningitidis special efforts were made to conduct a country-wide campaign with the new vaccine in late 2010 and before the onset of the next epidemic meningococcal disease season beginning in January 2011. In the ensuing five months (July-November 2010) the following challenges were successfully managed: (1) doing a large safety study and registering the new vaccine in Burkina Faso; (2) developing a comprehensive communication plan; (3) strengthening the surveillance system with particular attention to improving the capacity for real-time polymerase chain reaction (PCR) testing of spinal fluid specimens; (4) improving cold chain capacity and waste disposal; (5) developing and funding a sound campaign strategy; and (6) ensuring effective collaboration across all partners. Each of these issues required specific strategies that were managed through a WHO-led consortium that included all major partners (Ministry of Health/Burkina Faso, Serum Institute of India Ltd., UNICEF, Global Alliance for Vaccines and Immunization, Meningitis Vaccine Project, CDC/Atlanta, and the Norwegian Institute of Public Health/Oslo). Biweekly teleconferences that were led by WHO ensured that problems were identified in a timely fashion. The new meningococcal A conjugate vaccine was introduced on December 6, 2010, in a national ceremony led by His Excellency Blaise Compaore, the President of Burkina Faso. The ensuing 10-day national campaign was hugely successful, and over 11.4 million Burkinabes between the ages of 1 and 29 years (100% of target population) were vaccinated. African national immunization programs are capable of achieving very high coverage for a vaccine desired by the public, introduced in a well-organized campaign, and supported at the highest political level. The Burkina Faso success augurs well for further rollout of the Men A conjugate vaccine in meningitis belt countries.
