When was the meningitis B vaccine introduced?
When was the meningitis B vaccine introduced?
On 14 June 2012, the FDA approved a combination vaccine against two types of meningococcal disease and Hib disease for infants and children 6 weeks to 18 months old. The vaccine, Menhibrix, prevents disease caused by Neisseria meningitidis serogroups C and Y and Haemophilus influenzae type b.
What protein was used to develop the latest meningococcal vaccine?
Serogroup B Meningococcal or MenB Vaccines GlaxoSmithKline formulates each 0.5-mL dose of Bexsero® to contain: 50 µg each of recombinant proteins Neisserial adhesin A (NadA), Neisserial Heparin Binding Antigen (NHBA), and factor H binding protein (fHbp) 25 µg of Outer Membrane Vesicles (OMV)
Who invented the meningococcal vaccine?
Rino Rappuoli is Global Head of Vaccines Research for Novartis Vaccines & Diagnostics. He discovered and developed the Meningitis B vaccine recently administered at Princeton.

How was the meningococcal vaccine made?
It’s made with the antigens contained in the outer polysaccharide or sugar capsule that surrounds the bacterium. The meningococcal conjugate vaccine or MCV4 was approved in 2005. It uses antigens taken from the polysaccharide capsule and then bound to a separate protein that targets the body’s immune cells.
How is conjugate vaccine made?
Similar to subunit vaccines, conjugate vaccines use only portions of the germ. Many bacteria molecules are coated by a sugar called polysaccharide. This coating hides or disguises the germ (antigens) so that the immature immune systems of infants are not able to recognize it.
Where did meningococcal come from?
Meningococcal disease is caused by strains of the bacterium called Neisseria meningitidis . It is transmitted through close and prolonged contact with mucus from an infected person. The subtypes are given different letters of the alphabet. The main types seen in Australia are Meningococcus B, W and Y.
Where did meningococcal disease originate from?
The first outbreak in Africa was recorded in the 1840s, but it wasn’t until 1887 that Austrian bacteriologist Anton Vaykselbaum identified meningococcal bacteria as a cause of meningitis. In 1890, Heinrich Quincke (1842–1922) used a procedure called lumbar puncture (LP) on a patient with suspected meningitis.
