Quick Facts About MenB

  • Serogroup B caused over 60% of all US meningococcal disease cases in patients aged 16-23 years, from 2015 to 2017; N=18815 LEARN MORE
  • To help protect against the 5 most common vaccine-preventable serogroups, 2 different types of vaccines are needed—one for MenACWY, and one for MenB11 Vaccination may not protect all recipients.

Oregon, Oregon State University New MenB Vaccination Requirement: December 2017

Corvallis: Oregon State University will require all Corvallis students aged 25 and under to be vaccinated for meningococcal B disease by February 15, 2018.

Massachusetts, UMass Amherst Outbreak: November 2017

Amherst, MA: December 5, 2017: An outbreak of meningitis was reported on November 16 at UMass Amherst. Two students were confirmed to have been diagnosed with meningococcal disease in October and November.

The Centers for Disease Control and Prevention (CDC) were involved in conducting the testing of the two students. The situation has been classified an outbreak because the two students infected contracted the same strain of serogroup B meningitis.

The classification of an outbreak means there is increased risk of contracting the disease both on- and off-campus. UMass has recommended the serogroup B meningococcal vaccine for all of its undergraduate students. Likewise, Amherst College Health Services has strongly recommended the serogroup B meningococcal vaccine for all Amherst College students who take classes or spend considerable time at UMass. The meningococcal vaccine required of all students before entering Amherst does not protect against this particular strain of meningitis.

In particular, OSU students aged 25 or younger and who live in on-campus housing or who are members of— or who visit— fraternal living groups associated with the university are urged to act on this recommendation.

Madison, WI, University of Wisconsin—Madison Case: October 2016

On October 27, 2016, a third case of meningococcal disease was confirmed on the UW— Madison campus.

Wisconsin, University of Wisconsin—Madison Outbreak: October 2016

Madison, WI: Three UW— Madison students were diagnosed with meningitis.  All three cases were the same strain of meningococcal disease serogroup B even though the students appeared to have no connections to each other.

Wisconsin, University of Wisconsin—Madison Case: October 2016

New Jersey, Rutgers University—New Brunswick Outbreak: June 2, 2016

New Brunswick, NJ: June 2, 2016: A match in the strain of bacteria in two students diagnosed with meningitis confirmed that there is an outbreak of this disease at Rutgers University—New Brunswick.

Two students were diagnosed with meningitis caused by Neisseria meningitidis, serogroup B. Special testing performed by the Centers for Disease Control and Prevention (CDC) showed that the bacteria from the two students are genetically indistinguishable (a match). Although no common link has been identified between the two students, the fact that the strains of MenB bacteria in the two students match indicates that the strain is present in the undergraduate population of that university, and that there is an outbreak.

The first student with meningococcal disease was hospitalized on March 18, 2016. The second was hospitalized on April 29. Close contacts of both students were identified and notified to receive prophylactic antibiotics. Both students have recovered.

Santa Clara, CA: An outbreak of meningitis at Santa Clara University prompted the administration of 4,923 doses of meningococcal B vaccine— which protects against the serogroup B strain of meningococcal infection— at 4 vaccination clinics on campus this past weekend.

Three Santa Clara University (SCU) students became ill on Sunday January 31st, and were confirmed to be infected with the bacteria Neisseria meningitidis, serogroup B.

BEXSERO is a vaccine indicated for active immunization to prevent invasive disease caused by Neisseria meningitidis serogroup B. BEXSERO is approved for use in individuals aged 10 through 25 years.

Approval of BEXSERO is based on demonstration of immune response, as measured by serum bactericidal activity against three serogroup B strains representative of prevalent strains in the United States. The effectiveness of BEXSERO against diverse serogroup B strains has not been confirmed.

Important Safety Information for BEXSERO

  • BEXSERO is contraindicated in cases of hypersensitivity, including severe allergic reaction, to any component of the vaccine, or after a previous dose of BEXSERO
  • Appropriate observation and medical treatment should always be readily available in case of an anaphylactic reaction following the administration of the vaccine
  • The tip caps of the prefilled syringes contain natural rubber latex, which may cause allergic reactions
  • Syncope (fainting) can occur in association with administration of BEXSERO. Ensure procedures are in place to avoid injury from falling associated with syncope
  • The most common solicited adverse reactions observed in clinical trials were pain at the injection site (≥83%), myalgia (≥48%), erythema (≥45%), fatigue (≥35%), headache (≥33%), induration (≥28%), nausea (≥18%), and arthralgia (≥13%)
  • Vaccination with BEXSERO may not provide protection against all meningococcal serogroup B strains
  • Some individuals with altered immunocompetence may have reduced immune responses to BEXSERO
  • Individuals with certain complement deficiencies and individuals receiving treatment that inhibits terminal complement activation (for example, eculizumab) are at increased risk for invasive disease caused by Neisseria meningitidis serogroup B even if they develop antibodies following vaccination with BEXSERO
  • Vaccination with BEXSERO may not result in protection in all vaccine recipients
