A More Thorough Look At Meningococcal Vaccines, Including The New B Vaccine
http://www.chop.edu/centers-programs/vaccine-education-center/vaccine-details/meningococcal-vaccine
"Although there are only five different types of meningococcus that commonly cause disease (types A, B, C, Y and W-135), it has been very difficult to make a vaccine that includes type B, and meningococcus type B accounts for two-thirds of meningococcal infections in infants and one-third of meningococcal infections in adolescents and adults. (Of note, two vaccines to prevent meningococcus type B were submitted for licensure to the Food and Drug Administration in 2014. Both are likely to be licensed for use in adolescents in 2015.)"

THE MENINGOCOCCAL B VACCINE DEBATE

Recently, a DU OP offered a quick interview newspaper article that only offer opinions, sans offering any actual explanations for those opinions. That OP also offered a link to an anti-vaccine page, which tends to make such an OP's real purpose highly questionable, IMO. I acknowledge that these pieces only tell the start of the story, but they tell much more of the story than the other OP. I think these pieces are a better place to start for people who want to understand the vaccine better.
