Meningococcal disease: Sumeyra’s story

Sumeyra contracted Meningococcal disease, a sometimes life-threatening illness when she was 20 years old. She had to be placed in a medically induced coma. Luckily Sumeyra survived, but she still suffers from the effects of Meningococcal disease today.



Meningococcal disease is a rare but often life-threatening disease caused by the bacterium Neisseria meningitidis (commonly known as the meningococcus). There are 13 strains of meningococcus. The strains that worldwide are the most common cause of disease are A, B, C, W and Y.

There has been a recent increase in strain W since 2013, which now makes up almost half of Australian cases. Meningococcal W presently has a higher death rate than the other strains because most cases are due to a particularly virulent strain.

Most meningococcal disease occurs in children aged under five years of age and in older adolescents and young adults.1

People with meningococcal disease can become extremely unwell very quickly. They may feel sicker than they have ever felt before. After being infected, it usually takes one to ten days for symptoms to appear. The possible symptoms are: fever, rash, headache, neck stiffness, sensitivity to light, muscle aches, cold hands and feet, confusion, irritability, joint pain, nausea and vomiting.

Babies often don’t have many of these symptoms but may be febrile, be slow or inactive, unsettled, drowsy, floppy and not feeding.

How it is spread

Meningococcus is only carried and passed on by humans. It is spread by coughing, sneezing and regular, close, prolonged household or intimate contact with infected secretions from the back of the nose and throat. The bacteria can only survive a few seconds outside the body so they cannot be picked up from the environment.

Carriage rates are highest in older teenagers.


People with meningococcal disease could develop a number of conditions:

  • An infection of the lining around the brain (meningitis)
  • An infection of the blood (septicaemia)
  • Joint infection (arthritis)
  • Lung infection (pneumonia)
  • Permanent brain damage
  • Death in up to 10%2

1 in 5 people3 who recover may have lingering health problems. Many of the problems get better with time. Some of the issues experienced are:

  • Skin scarring (1 in 30)
  • Limb deformity
  • Deafness
  • Blurring and double vision
  • Learning difficulties

Immunisation is the best protection against meningococcal disease.


Who should get immunised?


Quadrivalent meningococcal disease vaccine protects against strains A, C, W and Y. It is part of the National Immunisation Program and is free for:

  • children aged 12 months
  • adolescents aged 14-19 years of age
  • those with aspen/hyposplenia, complement deficiency or on eculizumab treatment
  • Aboriginal and Torres Strait Islander children at 12 months and for adolescents 15-19 years of age

Vaccine is also available as a private prescription for:

  • some travel destinations, occupations and medical conditions
  • anyone over 2 months* wanting to protect themselves or their family from these strains of meningococcal disease4,5


Meningococcal B vaccine is available on private prescription for:

  • Infants, young children, adolescents, young adults living close together, some medical conditions and occupations
  • Anyone over 6 weeks* wanting to protect themselves or their family from this strain of meningococcal

* MenBV is registered for use from 2 months of age. However, the 1st dose can be given as early as 6 weeks of age to align with the schedule for other routine infant vaccines.


From 1 October 2018 Meningococcal B vaccinations have been available in a phased implementation in South Australia. From 1st July 2020, see here.


Meningococcal C disease is now very well controlled with only a handful of cases per year.

    5. Meningococcal vaccines for Australians/NCIRS Fact sheet: 1 July 2020


If meningococcal disease is suspected, an antibiotic (usually penicillin) is given immediately by injection. People with meningococcal disease are almost always admitted to hospital and may require admission to an intensive care unit.

Info for Clinicians

  • Since the introduction of MenACWY vaccination programs, the incidence of MenW disease has reduced and the overall rate of IMD fell to 0.8 per 100,000 in 2019. Currently, MenB and MenW cause the most meningococcal disease in Australia.3


    From 2002 to 2015 the predominant meningococcal serogroup in Australia was serogroup B. However, the incidence of serogroup B has declined in the absence of any significant vaccine use. In 2018, MenB became the predominant strain once again.

    Notifications of MenW doubled from 2014 (17) to 2015 (34), then more than tripled in 2016 (109) surpassing serogroup B (92 cases).1  

    In 2017, MenW (37%) and MenB (36%) emerged as predominant strains. In 2017, MenW notifications dramatically increased to 141 and MenB notifications to 137.2

    In 2018 MenW (36%) and MenB (42%) emerged as predominant strains with MenB (119 cases) surpassing MenW (100 cases)³

    Many of the MenW cases belong to the hypervirulent sequence type (ST) 11. ST 11 is associated with a higher risk of invasive disease, complications and a higher case fatality rate.


    MenC, the target of a national immunisation programme since 2003, has dramatically declined from 225 notifications in 2002 to 3 notifications in 2016 (a 99% decline). In 2017, MenC notifications increased to 14 and declined to 4 in 2018.2,3


    There has been an increase in serogroup Y disease from 12 cases in 2014 to 41 cases in 2016 to 75 cases in 2017 and a decline to 45 in 2018.Men ACWY vaccination programs have seen a drop in MenW and MenY in 2018.

    Serogroup A remains rare in Australia.


    Most meningococcal disease occurs in children aged less than 5 years of age and young people aged 15-24 years. MenW also has its peak in these age groups however, it is also somewhat increased in older adults. MenW accounted for 59% of Invasive Meningococcal Disease (IMD) in adults aged over 65 years in 2016.5

  • About one in 10 people can have meningococcal bacteria in their throat or nose. These very rarely cause illness.


    Adolescents have the highest carriage rates, peaking in 19-year olds, and so play an important role in transmission.6

  • A common presentation of meningococcal serogroup W disease in Australia has been severe sepsis. Classical meningitis symptoms have been less common. Serogroup W disease has also been associated with atypical presentations, such as septic arthritis, pneumonia and epiglottitis, in up to 20% of cases.9

  • See reference 10

    Individuals at greater risk of meningococcal infection:

    • Immunocompromised due to: Certain disorders of the immune system (particularly complement deficiencies) – HIV infection, Haemotapoetic stem cell transplant
    • Certain medical treatments (e.g. eculizimab)
    • Asplenia
    • Occupational exposure in labs
    • Exposure to smokers (who are more likely to be carriers)
    • Crowded living conditions
    • Intimate kissing with multiple partners
    • Recent or current viral infection
    • Aboriginal and/or Torres Strait Islander people (Up to 19 years of age)
  • Vaccines

    Three types of meningococcal disease vaccines are available in Australia:

    • meningococcal C conjugate vaccine (MenCCV) is available as:

    – a single vaccine (NeisVac-C)
    – a combination with Haemophilus type B (Menitorix)

    • recombinant meningococcal B vaccines (MenB) Bexsero, Trumenba
    • quadrivalent (A, C, W, Y) meningococcal conjugate vaccines (4vMenCV): Menactra, Menveo and Nimenrix

    **Menveo and Nimenrix are preferred for children ≥ 2 years. If unavailable, use Menactra.


    Administering quadrivalent meningococcal disease vaccines

    Menactra is in a liquid form and simply drawn up and administered to the individual.


    Menveo* and Nimenrix** consist of a powder and a liquid which need to be combined before they are administered.
