Yay, science. A new vaccine for meningitis A – that disease killing thousands of people in the central African “meningitis belt” annually – has been released. Which is good, but even better is the fact that it’s way cheaper and more effective than whatever we were using before.
Say the New Scientist folk:
MenAfriVac is much cheaper than existing meningitis A vaccines, at 50¢ compared with $120 per dose. It is also more potent. Unlike conventional vaccines, which are based on sugars resembling those on the surface of Neisseria meningitides, a bacterium that causes meningitis, the new vaccine splices the sugars to a carrier protein that is better at stirring up the body’s immune system. “It makes the immune response much more vigorous,” says Marc LaForce, director of the global Meningitis Vaccine Project, which developed MenAfriVac.
Antibodies against the bacterium continue to be produced long after vaccination, providing hope that a single jab may be enough to give lifelong protection.
So yeah, I mean MenAfriVac is a clunky name, but these dudes are scientists, not stuff-namers.
