Meningococcal Disease & Vaccine Information
Meningococcal: The Disease
Meningococcal disease is a bacterial illness caused by the aerobic, gram-negative bacteria Neisseria meningitidis (N. meningitidis). Thirteen types (serogroups) of N. Meningitis or meningococci have been identified with six found to be responsible for epidemics resulting in invasive meningococcal disease. Meningitis is the most common presentation of invasive meningococcal disease and accounts for approximately 75 percent of all cases.
Symptoms of meningitis begin to appear between 3 and 7 day after exposure to meningococcal bacteria. At first, symptoms may appear mild and similar to cold or flu symptoms and may include headache, fever, aches and pains. As the illness progresses, additional symptoms can include skin rash, severe headache, stiff neck, nausea, vomiting, inability to look at bright lights, mental confusions and irritability, extreme fatigue/sleepiness, convulsions and unconsciousness. In babies, symptoms can include a high-pitched moaning cry, difficulty or refusal to feed, and the fontanel, the soft area on the top of the head, may also be bulging. Learn more about Meningococcal…
There are four FDA approved meningococcal vaccines currently available for use in the United States. Two vaccines, Menectra (Sanofi Pasteur) and Menveo (Novartis/GlaxoSmithKline) conjugate vaccines target serogroups A, C, Y and W-135 meningococcal bacteria and two vaccines, BEXSERO (Novartis/GlaxoSmithKline) and TRUMENBA (Wyeth/Pfizer) recombinant vaccines target serogroup B meningococcal bacteria.
The CDC’s Advisory Committee on Immunization Practices (ACIP) recommends that the first dose of meningococcal conjugate vaccine targeting serogroups A, C, Y and W-135 (Menectra or Menveo) be administered at age 11-12 with a second booster dose given at the age of 16. ACIP also recommends that high risk children between 2 months and 10 years and high risk adults be vaccinated with meningococcal conjugate vaccine. While the CDC recommends meningococcal serogroup B vaccines for high risk adults, meningococcal group B vaccines have not received FDA approved for use in persons over the age of 25. Additionally, TRUMENBA and BEXSERO vaccines are not interchangeable and the same vaccine brand must be used for all administered doses. Learn more about Meningococcal vaccine…
Meningococcal Quick Facts
- Meningococcal disease is a serious and potentially life-threatening illness caused by the bacteria Neisseria meningitides. Most frequently, the illness can result in inflammation of the meninges of the brain (meningitis) and a serious bloodstream infection (septicemia/meningococcemia). Invasive meningococcal disease can also present as arthritis and pneumonia.
- Meningococcal disease is not easily spread and requires one to be susceptible to the infection and to have regular close contact with a person who is colonizing the bacteria.
- Meningococcal rates are low in the U.S. and have steadily declined since the 1990’s. In 2017, there were approximately 350 cases and 45 deaths (13.1 percent fatality rate) attributed to meningococcal disease. Individuals most at risk for contracting meningococcal disease are babies under a year old and young adults between the ages of 16 and 23. Continue reading quick facts…

- The CDC recommends all children receive their first dose of meningococcal serogroup A, C, Y and W-135 conjugate vaccine at age 11-12 and an additional booster dose at age 16. The booster dose recommendation was made in 2010 after studies noted that only 50 percent of adolescents vaccinated at age 11-12 had sufficient vaccine acquired antibodies to protect them against meningococcal disease five years post-vaccination.
