WHO – Nigeria Gets 500000 Meningitis Vaccines. 820000 More Coming From UK. Nigeria has received 500,000 doses of meningitis C containing vaccine to combat the epidemic in the country, according to The World Health Organization, WHO. The doses were sent by the International Coordinating Group (ICG) on Vaccine Provision, an organisation that coordinates the provision of vaccines during outbreak emergencies. Since the beginning of this year, the country has reported 4637 suspected cases and 489 deaths across five states.
This was confirmed by the World Health Organisation’s Country Representative to Nigeria, Doctor Wondimagegnehu Alemu, who also said in a statement in Abuja today, that Nigeria is to get additional eight hundred and twenty thousand Meningitis C vaccines from the United Kingdom government. He said the vaccines, funded by Gavi, the Vaccine Alliance, have been administered in Zamfara and Katsina states where the disease was most endemic.
He said WHO’s Country Office in Nigeria, including a number of field offices, have been supporting the government since the meningitis outbreak began. WHO Country Representative also stated that the Nigeria Centre for Disease Control, with support from WHO, the US Centre for Disease Control, UNICEF and other partners were leading the response to the on-going outbreak.
He said these Organisations were also carrying out intensified surveillance, capacity building for case management and risk communication.
In the last week, the ICG, which is managed by the International Federation of Red Cross and Red Crescent Societies (IFRC), Médecins sans Frontières (MSF), the United Nations Children’s Fund (UNICEF), and WHO, has also sent 341 000 doses of the Gavi-supported meningitis C-containing vaccine to Niger, where there are over 1300 suspected cases of the disease in districts that border with Nigeria and in the Niamey region of the country.
In addition to the use of vaccinations to prevent the transmission of meningitis, 20 000 vials of antibiotics have been sent by the ICG to treat people who have the disease in Nigeria. “Vaccination can drastically reduce the magnitude of the epidemic,” says Dr Sylvie Briand, Director of Infectious Hazard Management for WHO. “But in addition, it is essential to strengthen the care of all those affected by the infection and to ensure those people living in hard-to-reach areas can get treatment.”
The Nigeria Centre for Disease Control, with support from WHO, US CDC, UNICEF and other partners, is leading and coordinating the response to the ongoing outbreak, including intensified surveillance, capacity building for case management and risk communication. WHO’s Country Office in Nigeria, including a number of field offices, have been supporting the government since the outbreak began. An additional team of WHO of meningitis experts has arrived in Nigeria to provide additional epidemic response. “In addition to improving the care of the sick, we are focusing on ensuring accurate information about the spread of the outbreak is available as quickly as possible to help us make the most effective use of vaccines,” says Dr Wondimagegnehu Alemu, WHO Representative to Nigeria.
Most vaccines currently being used for meningitis C outbreaks in Africa are polysaccharide vaccines, which are in short supply as they are being phased out in other parts of the world. The more effective and long-lasting conjugate vaccines, however, are not readily accessible for outbreak response in the region. The ICG global emergency stockpile currently has approximately 1.2 million doses of meningitis C-containing vaccines left.
“The very limited supply of vaccines to control outbreaks of meningitis C can affect our ability to control these epidemics,” says Dr Olivier Ronveaux, WHO meningitis expert. “In the long term, the accelerated development of affordable and effective conjugate vaccines to cover all epidemic types of meningitis is a high priority for WHO and partners.”
Meningococcal meningitis is a bacterial form of meningitis, a serious infection of the thin lining that surrounds the brain and spinal cord and can cause severe brain damage. Meningococcal meningitis is fatal in 50% of cases if untreated. Though cases of meningitis occur throughout the world, large, recurring epidemics affect an extensive region of sub-Saharan Africa known as the “meningitis belt” which includes 26 countries from Senegal in the west to Ethiopia in the east.
There are several different types of meningococcal meningitis (A, C, W, etc.) that can cause epidemics. Substantial progress has been made in recent years in protecting Africa from disease due to one of the main epidemic types, through the successful introduction of the Men A conjugate vaccine (MACV) against meningitis A. Since MACV was introduced in 2010, more than 260 million people have been vaccinated across 19 countries. This has resulted in a reduction of the number of meningitis cases by more than 57%. Much work, however, remains to be done to protect the region from meningitis C outbreaks and other types of the disease.
In the past, Nigeria has suffered large-scale outbreaks of meningitis A. In 2009, such an outbreak in the country caused over 55 000 cases with close to 2500 deaths. Niger was also affected, with 13 000 cases and 550 deaths. However, preventive mass vaccination campaigns supported by Gavi and partners, using the safe and effective MACV in Niger (2010-11) and Nigeria (2011-14) have provided high and long-term protection against the bacteria. Since 2010, less than 20 cases of meningitis A have been reported from all vaccinated areas in the region. WHO recommends the continued roll-out of the Men A conjugate vaccine campaigns along with its introduction into routine immunization to prevent a major recurrence of devastating meningitis A epidemics.
Since 2013, there have been outbreaks of meningitis C in Nigeria, initially limited to a few areas in Kebbi and Sokoto states in 2013 and 2014. In 2015, however, there were more than 2500 cases of the disease across 3 states in Nigeria as well as 8500 cases in Niger.
