Meningitis C can cause severe brain damage and is fatal in
50% of cases if untreated. There were 12,000 cases of meningitis in Niger and
Nigeria and 800 deaths in the first six months of the year but with cases
rising since 2013, the fear is that next year’s meningitis season, which begins
in January, could see a much larger number of cases.
A shortage of meningitis C vaccine is threatening to
jeopardise the ability to cope with a potential outbreak of the disease in
Africa, international public health organisations, including the World Health
Organisation, have warned. The International Coordinating Group for Vaccine
Provision for Epidemic Meningitis Control, which also comprises the
International Federation of Red Cross and Red Crescent Societies (IFRC), and
Médecins sans Frontières (MSF) are appealing to pharmaceutical companies to
help them by plugging the gap. They say pharmaceutical companies have told them
they are unable to supply the newer, more effective conjugate vaccines, which
provide longer lasting immunisation than the old polysaccharide vaccines.
“What we have told the manufacturers is we want the
conjugate vaccine to be able to prevent epidemics for longer periods but they
will not produce the vaccine in enough quantities at affordable prices,” explained
Dr William Perea, coordinator of the control of epidemic diseases unit at WHO. “Either
they help us have affordable conjugate vaccines or we’ll have to use an old
vaccine that doesn’t provide us with the same quality,” said Perea.
MSF’s international medical coordinator, Dr Myriam Henkens,
emphasised the importance of a multivalent vaccine – one that covers different
strains of the disease: “We need vaccine manufacturers to plan production of a
multivalent vaccine now to allow sufficient lead time and capacity to meet this
demand.”
As well as the extra protection afforded by the conjugate
vaccines, they are also suitable for children, unlike the polysaccharide
version. However, according to WHO figures, they generally cost at least 10
times more than polysaccharide vaccines, which are priced at around $4 to $5.
Even with the manufacturers offering the conjugate vaccines at $25 a dose, for
the five million doses required that amounts to $125m as opposed to $25m for
the polysaccharide vaccines.
