Nigeria has become the first country in the world to roll out a new vaccine – Men5CV – recommended by the World Health Organization (WHO), to protect people against meningitis.
The World Health Organisation (WHO), in a statement on Friday, said that the vaccine would protect people against five strains of Meningococcus bacteria and described Nigeria’s feat as historic.
It said that health workers would begin an immunisation campaign aimed at reaching one million people.
The statement said that the vaccine and emergency vaccination activities are funded by Gavi, the Vaccine Alliance, which funds the global meningitis vaccine stockpile and supports lower-income countries with routine vaccination against meningitis.
According to the WHO, Nigeria is one of the 26 meningitis hyper-endemic countries in Africa, situated in the area known as the African Meningitis Belt.
It noted that in 2023, there was a 50 per cent jump in annual meningitis cases reported across Africa.
“In Nigeria, an outbreak of Neisseria meningitidis (meningococcus) serogroup C outbreak, led to 1,742 suspected meningitis cases, including 101 confirmed cases and 153 deaths in seven of the 36 Nigerian states between October 2023 and March 2024.
The states are Adamawa, Bauchi, Gombe, Jigawa, Katsina, Yobe, and Zamfara.
“To quell the deadly outbreak, a vaccination campaign was undertaken on March 25–28, 2024, to initially reach more than one million people aged 1-29 years,” it said.
The statement noted that meningitis is a serious infection that leads to the inflammation of the membranes (meninges) that surround and protect the brain and spinal cord.
“There are multiple causes of meningitis, including viral, bacterial, fungal, and parasitic pathogens.
“Symptoms often include headache, fever, and stiff neck. Bacterial meningitis is the most serious and can also result in septicaemia (blood poisoning). It can seriously disable or kill within 24 hours,” the statement added.
It quoted Dr Tedros Ghebreyesus, WHO Director-General, as saying that meningitis was an old and deadly foe, adding that the new vaccine holds the potential to change the trajectory of the disease, preventing future outbreaks and saving many lives.
“Nigeria’s rollout brings us one step closer to our goal of eliminating meningitis by 2030,” Ghebreyesus said.
He said that the revolutionary new vaccine offers a powerful shield against the five major strains of the meningococcal bacteria – A, C, W, Y, and X – in a single shot.
All five strains cause meningitis and blood poisoning.
According to him, this provides broader protection than the current vaccine used in much of Africa, which is only effective against the A strain.
He said that the new vaccine has the potential to significantly reduce meningitis cases and advance progress in defeating meningitis.
“This is especially important for countries like Nigeria, where multiple serogroups are prevalent.
“The new vaccine uses the same technology as the meningitis A conjugate vaccine (MenAfriVac®), which wiped out meningococcal A epidemics in Nigeria,” the WHO boss said.
The statement quoted Prof. Muhammad Pate, Nigeria’s Minister of Health and Social Welfare, as saying that Northern Nigeria, particularly the states of Jigawa, Bauchi, and Yobe, were badly hit by the deadly outbreak of meningitis.
“This vaccine provides health workers with a new tool to both stop this outbreak and also put the country on a path to elimination,” Pate said.
According to him, Nigeria has done a lot of work preparing health workers and the health system for the rollout of the new vaccine.
“We got invaluable support from our populations in spite of the fasting period, and from our community leaders, especially the Emir of Gumel in Jigawa, who personally launched the vaccination campaign in the state.
“We’ll be monitoring progress closely and hopefully expand the immunisation in the coming months and years to accelerate progress,” he said.
The minister said that the new multivalent conjugate vaccine took 13 years of effort and was based on a partnership between PATH and the Serum Institute of India.
“Financing from the UK government’s Foreign, Commonwealth, and Development Office was critical to its development,” he said.
Pate said that in July 2023, WHO prequalified the new Men5CV vaccine (which has brand name MenFive®), and in October 2023, it issued an official recommendation to countries to introduce the new vaccine.
According to him, Gavi allocated resources for the Men5CV rollout in December 2023, which are currently available for outbreak response through the emergency stockpile managed by the International Coordinating Group (ICG) on vaccine provision.
He added that the rollout, through mass preventive campaigns, was expected to start in 2025 across countries of the Meningitis Belt.
