Nigeria has achieved a world first by launching a revolutionary vaccine that fights five dangerous strains of meningitis. The Men5CV vaccine rollout stands as a historic milestone to combat this deadly disease. The timing proves critical as Nigeria struggles with a severe outbreak that killed 153 people across seven states from October 2023 to March 2024. Nigeria’s position as one of 26 countries in Africa’s Meningitis Belt makes it vulnerable to recurring epidemics. The continent saw meningitis cases jump by 50% last year. PATH and the Serum Institute of India’s 13-year partnership led to this breakthrough vaccine that protects against five meningococcus strains (A, C, W, Y, and X). Previous vaccines only targeted the A strain. The WHO endorsed this vaccine in October 2023, and the current vaccination campaign will protect over one million people aged 1-29 years. This effort marks a vital step toward eliminating meningitis as a public health threat by 2030.

“Meningitis, a vaccine-preventable disease, is causing unnecessary and preventable deaths in many populations. WHO has prequalified the Men5CV vaccine as safe and effective, capable of preventing future outbreaks and saving lives by protecting against the five bacterium types causing meningitis.” — Dr Walter Kazadi Mulombo, WHO Country Representative in Nigeria
Nigeria made history in March 2024 by becoming the first country to use the new Men5CV vaccine. This breakthrough marks a big step forward to curb meningitis. The vaccine protects against five strains of meningococcus bacteria in one shot, which offers better coverage than older vaccines.
153 Lives Lost in Recent Outbreak Prompts Urgent Action
A severe meningitis outbreak has devastated communities in northern Nigeria. The country recorded 1,742 suspected meningitis cases from October 2023 to March 2024. These cases included 101 confirmed infections and 153 deaths across seven states. The affected regions include:
- Adamawa
- Bauchi
- Gombe
- Jigawa
- Katsina
- Yobe
- Zamfara
The outbreak is part of a bigger crisis in Africa, where meningitis cases jumped 50% last year. Northern Nigeria felt the worst impact, especially in Jigawa, Bauchi, and Yobe states.
“Northern Nigeria, particularly the states of Jigawa, Bauchi and Yobe were badly hit by the deadly outbreak of meningitis, and this vaccine provides health workers with a new tool to both stop this outbreak but also put the country on a path to elimination,” stated Professor Muhammad Ali Pate of the Nigerian Ministry of Health and Social Welfare.
Nigeria’s struggle with meningitis follows a troubling pattern. The country faced another major outbreak in 2017 with 1,407 reported cases and 211 deaths across 40 local government areas in five states. Zamfara, Katsina, and Sokoto states made up 89% of reported cases.
From October 2022 to April 2023, the country saw 1,686 suspected cases, 532 confirmed cases, and 124 deaths across 81 local government areas in 22 states. Children aged 1 to 15 years had the most cases, and males made up 57% of suspected infections.
Nigerian authorities launched an emergency vaccination drive on March 25-28, 2024. The campaign targets more than one million people aged 1-29 years. This age group faces the highest risk of meningitis infection. Kebbi and Sokoto States will get the vaccine first, followed by Yobe State when more doses arrive.
The dry season from December to June creates perfect conditions for meningitis outbreaks. Cases peak between March and April when humidity drops and dust levels rise across the region.
“The arrival of the Men5CV vaccines is a vital milestone in Nigeria’s response to the current meningitis outbreak,” health officials noted. They stressed the need for quick deployment to stop the spread. The vaccine helps Nigeria’s health system fight an outbreak that has killed over 70 people and affected more than 800 cases across 23 states.
WHO Celebrates Historic First in Global Health
The World Health Organization praised Nigeria’s groundbreaking use of the Men5CV vaccine as a game-changer in global health. Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, said: “Meningitis is an old and deadly foe, but this new vaccine holds the potential to change the trajectory of the disease, preventing future outbreaks and saving many lives”.
He added that “Nigeria’s rollout brings us one step closer to our goal to eliminate meningitis by 2030”. This goal serves as the life-blood of WHO’s global health strategy, with the Men5CV vaccine playing a key role.
The Men5CV vaccine, branded as MenFive, offers better protection than previous options. Older vaccines used in Africa worked mainly against the A strain of meningococcal bacteria. MenFive protects against five major strains: A, C, W, Y, and X. This broad protection helps Nigeria where multiple strains spread at once.
Andrew Mitchell, UK Minister for Development and Africa, emphasized the vaccine’s importance: “The rollout of one million vaccines in northern Nigeria will help save lives, prevent long-term illness and boost our goal of defeating meningitis globally by 2030”.
Dr. Nanthalile Mugala, PATH’s Chief of Africa Region, put things in perspective: “Year after year, meningococcal meningitis has tormented countries across Africa”. MenFive’s arrival in Nigeria “heralds a transformative era in the fight against meningococcal meningitis in Africa”.
Nigeria belongs to the “meningitis belt” that runs across Africa from Senegal to Ethiopia. This region puts about 500 million people at risk. Meningitis leaves lasting damage – one in four survivors faces permanent disabilities like hearing loss, seizures, limb weakness, vision problems, speech issues, memory loss, and even limb amputations.
Nigeria’s choice to use Men5CV shows its focus on public health and stopping meningitis outbreaks. Support from Gavi, WHO, and UNICEF helped Nigeria roll out this resource quickly.
Nigeria’s Health Minister explained how this fits into bigger plans: “Through the Nigeria Health Sector Renewal Investment Initiative and the Sector-Wide Approach, we have prioritized epidemic preparedness and rapid response as part of our broader health security agenda”. The Men5CV vaccine helps fight the current outbreak and strengthens Nigeria’s long-term health security.
This success builds on earlier efforts. Nigeria used the meningococcal A (MenA) conjugate vaccine against serogroup A from 2011-2022. Prevention campaigns have protected over 100 million people aged 1 to 29 years. The MenA vaccine joined routine immunizations in 2019. Yet outbreaks continued, especially from meningococcus serogroup C.
The Men5CV vaccine’s first use marks a vital step forward in Nigeria’s fight against this ongoing health threat. It brings hope to communities that have suffered from devastating meningitis outbreaks.
How Does the New MenFive Vaccine Transform Protection?
The MenFive vaccine marks a fundamental change in meningitis prevention across Africa’s meningitis belt. This revolutionary preventive measure uses advanced conjugate technology that expands protection against multiple dangerous strains of meningococcal bacteria.
One Shot Shields Against Five Deadly Strains
A single 0.5 mL dose of MenFive provides unmatched protection. The vaccine shields people against five major strains of meningococcal bacteria: A, C, W, Y, and X. This five-strain approach has changed vaccine technology, particularly in regions where multiple serogroups spread at once.
The vaccine works through a conjugate design that links bacterial capsule polysaccharides to a carrier protein. This scientific method improves immune response in several key ways:
- Activates a broader part of the immune system
- Provides longer-lasting protection against disease
- Creates immunological memory for sustained immunity
- Protects children younger than 2 years of age
The vaccine builds on the success of MenAfriVac®, which showed remarkable results in stopping meningococcal A epidemics in Nigeria. MenFive extends this proven technology by adding four more dangerous strains.
MenFive stands alone as the only vaccine that protects against serogroup X meningococcal meningitis. This strain has caused many recent African meningitis outbreaks. Clinical studies reveal that 97% of MenFive recipients developed strong immunity against Group X meningococci.
Detailed clinical trials across multiple countries have proven MenFive’s safety and effectiveness. Phase 3 randomized trials support its use in routine childhood immunization programs where meningitis is common. The vaccine matches existing quadrivalent MenACWY-TT vaccines used in the US since 2005, with a strong safety record.
MenFive’s temperature stability makes it ideal for African settings. The vaccine can reach remote communities without strict cold chain requirements. This feature helps protect areas with limited health infrastructure.
WHO advises all meningitis belt countries to add MenFive to their routine immunization programs. They recommend one dose between 9 to 18 months of age. High-risk areas should run catch-up campaigns for people aged 1-19 years to maximize protection.
Previous Vaccines Limited to Single Strain Coverage
Before MenFive, Africa relied on vaccines that only protected against one strain—usually serogroup A. People remained vulnerable to other common strains, leaving major gaps in public health protection.
MenAfriVac’s 2010 introduction stopped serogroup A epidemics in sub-Saharan Africa. This breakthrough helped, but other serogroups continued causing outbreaks across the region.
These limitations created problems because:
- Multiple serogroups (A, C, W, Y, and X) cause meningitis and blood poisoning in Africa
- Serogroup X outbreaks increased with no vaccine protection
- Outbreaks continued despite MenAfriVac use
Cost kept most multi-strain meningococcal vaccines out of Africa. This economic barrier left protection incomplete, and outbreaks continued despite some vaccine coverage.
Serum Institute of India developed MenFive with PATH and UK government funding to fill these gaps. The 13-year development focused on creating an affordable solution for African meningitis belt countries.
Gavi’s Senior Program Manager Cassandra Quintanilla emphasized MenFive’s importance: “The introduction of MenFive aligns with broader efforts to transition from reactive vaccination to preventive immunization strategies, paving the way for sustained protection against meningitis outbreaks”.
MenFive plays a vital role in the global plan to defeat meningitis by 2030. The predicted cost of US$11.02 per dose makes it more accessible than other multi-strain options. Countries can now include MenFive in routine programs instead of relying on emergency campaigns.
MenFive’s broad protection tackles Africa’s complex meningococcal disease patterns, where multiple strains spread unpredictably. Countries using MenAfriVac should switch to MenFive for better protection under one vaccine.
The five-strain formula simplifies vaccination compared to multiple separate shots. This streamlined approach improves coverage rates, particularly in areas with limited resources.
This shift from single to five-strain protection has transformed meningitis prevention. Countries can now protect against five dangerous strains through one program instead of responding to each outbreak separately.
Families Celebrate as Vaccination Campaign Reaches One Million People

A life-saving vaccination campaign launched in March 2024 has reached over one million vulnerable Nigerians. The campaign brings hope to communities hit hard by the deadly meningitis outbreak. Health workers moved through northern states from March 25-28 to give the groundbreaking five-in-one vaccine to people who needed it most. This massive public health effort marks a turning point for families who have seen the disease’s devastating effects.
Northern Nigerian Communities Hit Hardest by Outbreaks
The meningitis crisis has hit northern Nigeria hardest, especially in Jigawa, Bauchi, and Yobe states. Yobe state reported at least 84 deaths from cerebrospinal meningitis by mid-April 2024. Health workers targeted these high-risk areas along with Kebbi and Sokoto states, where many lives were lost to the disease.
“Containing the meningitis outbreak in a prolonged humanitarian crisis state like Yobe is critical not only for preventing unnecessary loss of life but also for preserving the health, well-being, and stability of affected populations,” noted health officials who coordinated the response. Health workers started in Potiskum and Nangare Local Government Areas (LGAs) in Yobe state and distributed 400,825 doses of the Men5CV vaccine.
The campaign focused on people aged 1-29 years who face the highest risk of meningitis infection. This targeted approach follows data that shows children and young adults are most likely to get the disease. Jigawa state’s numbers show that 945,043 children aged 1-19 years now have protection through the campaign.
“Northern Nigeria, particularly the states of Jigawa, Bauchi and Yobe were badly hit by the deadly outbreak of meningitis, and this vaccine provides health workers with a new tool to both stop this outbreak but also put the country on a path to elimination,” explained Professor Muhammad Ali Pate of the Nigerian Ministry of Health and Social Welfare.
Parents Share Stories of Hope and Relief
Families across affected communities welcomed the vaccination campaign with open arms. Healthcare workers saw large crowds as they moved between villages and towns. Many parents brought several children to get vaccinated.
“We were moving from one community to the other to vaccinate people and the turnout was very impressive. Over 1,200 people were vaccinated in the areas I visited,” reported Marafa, a vaccinator during the five-day mass campaign. People’s strong response shows they better understand meningitis risks and prevention.
The Men5CV vaccine gives many families their first chance at complete protection against the disease. Before this, communities only had vaccines that worked against one strain of meningitis, which left them open to other strains.
Musa Ismaila, a 45-year-old community leader in Gumel LGA, shared his point of view: “Initially, we didn’t take meningitis seriously until the situation escalated. Many children were infected. Two of my neighbor’s children came down with the disease. I would say the vaccine changed the situation for good”.
His story shows the positive changes happening across northern Nigeria as communities see how well the vaccination campaign works. Each protected child means less potential suffering since meningitis often leaves survivors with lasting problems like hearing loss, seizures, and brain damage.
The World Health Organization supports these efforts beyond giving out vaccines. They trained and sent at least 100 community-recognized teams to search for cases in high-risk areas. These teams spread awareness about preventing meningitis and help find suspected cases early.
Community Leaders Drive Participation Despite Fasting Period
The campaign faced a challenge because it happened during Ramadan when many Muslim Nigerians fast during daylight hours. Religious and traditional leaders stepped up to support the effort, which helped achieve high turnout rates.
Jigawa state’s Emir of Gumel kicked off the vaccination campaign himself, which gave it more credibility. His public backing helped convince people who worried about getting shots while fasting.
“We got invaluable support from our populations despite this fasting period and from our community leaders especially the Emir of Gumel in Jigawa state who personally launched the vaccination campaign in the state,” acknowledged Professor Pate [142]. This teamwork between health officials and traditional leaders proved vital to the campaign’s success.
Yobe state saw similar support from traditional structures. Hakimi Mai Hassan, who represents the Emir of Fika (Chairman Council of Chiefs Yobe state), stressed how vital community-based approaches are: “Engaging with the community members through the traditional/religious leaders is one of the most effective ways to contain this outbreak of meningitis”.
Religious leaders helped address concerns about whether vaccines would break Ramadan fasts. Their help proved vital since many people hesitated until they learned vaccination wouldn’t affect their religious practice.
“Some people were afraid of the vaccine. I took it as a community leader and that changed their mindset,” explained Musa Ismaila, describing how his public vaccination helped his community overcome their fears.
The WHO, with funding from USAID/BHA, worked closely with religious, traditional, and community leaders across affected areas. This complete approach ensured people widely accepted the vaccination effort.
Dr. Kumshida Yakubu Balami, WHO Northeast Nigeria Interim Emergency Manager, highlighted this strategy’s importance: “Most at times in an outbreak, communities who are vulnerable to epidemic diseases suffer the most. Notwithstanding, the WHO is constantly reviewing/re-strategizing the community engagement approach to a more sustainable and effective way especially ensuring no vulnerable person is left behind”.
These coordinated efforts protected nearly one million people in what officials called “a huge success”. The campaign showed how modern medical care and traditional community structures can work together, creating a blueprint for future public health work in the region.
“Every child deserves protection from life-threatening diseases like meningitis,” emphasized UNICEF representatives supporting the initiative. That protection has finally reached families across northern Nigeria.
What Makes the African Meningitis Belt So Vulnerable?

The “African meningitis belt” stretches from Senegal to Ethiopia, creating perfect conditions for deadly meningitis outbreaks. This vast region of sub-Saharan Africa faces constant health threats. Nigeria’s new vaccine initiative stands out as a crucial breakthrough in this challenging landscape.
26 Countries Face Recurring Epidemic Threats
The meningitis belt puts roughly 500 million people at risk of infection across 26 countries. Burkina Faso, Chad, Ethiopia, and Niger bear the heaviest burden, making up 65% of Africa’s total cases. Some communities see attack rates as high as 1,000 cases per 100,000 people during severe epidemics.
Several factors make this region especially at risk:
- Seasonal climate patterns: Low humidity and high dust levels damage throat membranes from December through June. This makes bacterial growth easier
- Environmental conditions: Cold nights and dust-filled winds during dry seasons weaken respiratory defenses
- Population movements: Disease spreads through pilgrimages, traditional markets, and people displaced by humanitarian crises
- Housing conditions: People living in crowded spaces pass the infection more easily
Recent decades show troubling changes in the meningitis belt. Epidemic cycles have grown shorter and less predictable since the early 1980s. The belt now reaches southward into new territories like Angola, Burundi, Democratic Republic of Congo, Rwanda, and Zambia.
These repeated epidemics strain already limited healthcare systems. Major outbreaks typically affect 100 to 800 people per 100,000 population [181]. The United States reported fewer than 800 total cases in 2011. The meningitis belt, by contrast, saw over 90,000 cases in 2009 alone.
50% Jump in Cases Reported Last Year Across Africa
Meningitis cases across Africa rose by about 50% last year. This surge demands better prevention methods. COVID-19 containment measures had briefly reduced respiratory disease transmission, leading to fewer cases.
The belt’s disease patterns remain hard to predict. The MenA conjugate vaccine’s success in 2010 virtually eliminated serogroup A epidemics in vaccinated areas. Other meningococcal serogroups – mainly C, W, and X – filled this gap.
The region’s mean temperature variation has nearly tripled over 30 years. This coincides with a 4.8% rise in global meningitis risk. Such climate changes worsen the seasonal vulnerability that has marked the meningitis belt for over 100 years.
Communities suffer beyond immediate deaths. Treatment saves many, but 10-15% still die. Among survivors, 10-20% develop lasting conditions like hearing loss, vision problems, epilepsy, or other neurological issues. Young children remain most vulnerable due to their developing immune systems.
Nigeria’s location in this high-risk region highlights its Men5CV vaccine program’s importance. As the first country to protect against five strains, Nigeria shows others how to tackle these complex health challenges.
The devastating epidemic cycles that hit the belt every 8-12 years might finally end. This new vaccine technology could turn “the meningitis belt” from an ongoing crisis into a chapter in medical history.
13-Year Journey Brings Life-Saving Innovation to Reality

Nigeria’s historic vaccine rollout tells a remarkable development story that spans more than a decade. The creation of the revolutionary MenFive vaccine started in 2010 and led to a scientific breakthrough that will change meningitis prevention throughout Africa.
PATH and Serum Institute of India Forge Critical Partnership
A breakthrough five-strain meningitis vaccine emerged from 13 years of collaboration between global health nonprofit PATH and the Serum Institute of India Pvt. Ltd. (SIIPL). Their partnership aimed to create an affordable solution for the African meningitis belt, where devastating epidemics have affected communities for generations.
“MenFive is a game-changer vaccine developed through a powerful 13-year collaboration between SIIPL, PATH, and vital support from the UK government, in the fight against meningococcal meningitis in Africa,” stated Adar Poonawalla, CEO of Serum Institute of India.
The team built on MenAfriVac’s success, a vaccine that eliminated meningococcal serogroup A outbreaks after its 2010 introduction. MenFive takes protection further by including five serogroups (A, C, W, Y, and X) in one formulation.
UK Government Funding Proves Decisive in Development
The UK government’s Foreign, Commonwealth and Development Office provided vital financial support that turned this innovation into reality. Their funding helped scientists create a pentavalent conjugate vaccine that low-resource settings could afford.
“This landmark scientific achievement will have huge implications for improving public health,” emphasized Andrew Mitchell, UK’s International Development Minister. “Having access to a new, affordable vaccine will save lives, prevent long-term illness, and move us closer to defeating meningitis by 2030”.
The development team prioritized accessibility above all. “Because some of the development costs were shared, and the manufacturers committed to creating meningitis vaccines for use in Africa, this makes it more affordable than vaccines produced by pharmaceutical companies in the Global North,” explained Professor Caroline Trotter, a meningitis expert.
WHO’s prequalification of the vaccine in July 2023 marked the end of this 13-year effort, allowing United Nations agencies and Gavi, The Vaccine Alliance to procure it.
Nigeria has made history by rolling out the Men5CV vaccine, marking a turning point in Africa’s fight against meningitis. This innovative vaccine protects against five dangerous meningitis strains with just one shot. It brings new hope to millions of people living in Africa’s meningitis belt.
The vaccine proved its worth during a severe outbreak that took 153 lives. PATH worked with the Serum Institute of India for 13 years to create this scientific breakthrough. Unlike older vaccines that only targeted one strain, Men5CV works against multiple bacterial strains at once.
This milestone will reshape public health in Africa. Men5CV’s complete protection helps WHO reach its goal to eliminate meningitis as a public health threat by 2030. Countries in the meningitis belt now have a powerful way to protect their people from deadly outbreaks that killed thousands in the past.
The vaccine’s low cost and easy access mean it can help people beyond Nigeria. Research shows it works well, and it stays stable in high temperatures. This makes it perfect for remote areas that don’t have good infrastructure. These benefits make Men5CV a game-changer for communities that faced repeated epidemics.
Nigeria’s brave move shows other countries how to fight meningitis. The success of this five-strain vaccine proves we can protect people from this deadly disease. It points to a future where meningitis no longer threatens millions of African lives.
