Meningococcal disease and vaccines
Meningococcal disease is caused by the bacteria Neisseria meningitidis. There are 13 known sub-types and of these, 5 are currently vaccine preventable (B and A, C, W, Y).
In 2018, the main serotypes causing disease in Australia are B, W and Y, with variations noted by state. The increase in Meningococcal W disease has been clearly outline and regularly updated by the Australian Department of Health (see references) Importantly, all of the meningococcal strains currently circulating in Australia are potentially vaccine preventable.
People with meningococcal disease can become extremely unwell very quickly. Invasive meningococcal disease (IMD) can cause meningitis (inflammation of the membrane covering the brain and spinal cord), septicaemia (infection in the blood) as well as other infections like pneumonia (lung infection), arthritis (inflammation of the joints) and conjunctivitis (eye infection). Mortality (death) can be as high as 5-10% and permanent lifelong complications can occur in 10-20% of those who survive. Disease is transmitted via respiratory droplets (sneezing and coughing etc.).
Prevention of meningococcal infection
There are vaccines available for protection against Meningococcal B and Meningococcal ACWY.
Meningococcal C vaccine has been free through the National Immunisation Program (NIP) in Australia since 2003. It is currently administered at 12-months of age as Menitorix® [Hib- MenC] vaccine.
A four-in one combination vaccine is available for protection against meningococcal serogroups A, C, W and Y.
There are currently three quadrivalent conjugate vaccines (4vMenCV) available for immunisation against Meningococcal A, C, W and Y.
- Nimenrix® (Pfizer) – For use from 6-weeks of age (see References)
- Menveo® (GSK) – For use from 6-weeks of age
- Menactra® (Sanofi) – For use from 9-months of age
Meningococcal A, C, W, Y vaccines can be administered at the same time as Menitorix® [Hib- MenC]. There are no safety concerns re- receiving additional Men C vaccine antigen. If not administered on the same day, MVEC recommend a 1-month interval between Menitorix® [Hib- MenC] and 4vMenCV [ACWY].
Menactra® is currently free on the NIP for Victrorian Year 10 students (time limited program ending December 31 2018).
Menactra® is also currently provided for free (time limited program ending December 31 2018) for all men who have sex with men (MSM).
A private script is required to purchase the Meningococcal A, C, W, Y vaccine if patients wish to be protected but do not meet the criteria on the NIP.
NB: It has been announced that Nimenrix® will be added to the NIP for infants aged 12 months of age at some point in the 2nd half of 2018. (Details to follow, refer to Media Release)
Table 1: Recommended MenACWY vaccine schedule (by brand) for healthy individuals, travellers and laboratory personnel
|Vaccine Brand¥||Course commenced at 6 weeks ≤8 months of ageY||Course commenced at 9 to ≤11 months of ageY||Course commenced at 1 – 2 years of age||Course commenced at ≥2 years of age†|
|Nimenrix®||2 doses (minimum 8 weeks apart) + 1 booster#||1 dose + 1 booster#||1 dose||1 dose|
|Menveo®||2 doses (minimum 8 weeks apart) + 1 booster#||1 dose + 1 booster#||2 doses (minimum 8 weeks apart)||1 dose|
|Menactra®||N/R*||1 dose + 1 booster#||2 doses (minimum 8 weeks apart)||1 dose|
# Booster dose at ≥12 months of age/8 weeks since previous dose (whichever is later)
Y Nimenrix® is currently not registered for use in this age group in Australia, but studies have shown it to be immunogenic in this age group (see References)
N/R – not currently registered in Australia for use in the specified age group
* There are no published clinical trials data on the use of Menactra® in infants younger than 9 months of age. Given that infants typically have weaker immune responses than toddlers and older children, the clinical effectiveness of Menactra® in young infants is not yet known. Therefore Menactra® is not recommended in this age group. MVEC preferentially recommend Nimenrix® or Menveo® (if available) in infants < 12-months
† There is no registered upper age limit for use of Menveo®. Although both Menactra® and Nimenrix ® are registered for use of up to 55 years of age only, either brands can be given to people over 55 years of age, as per The Australian Immunisation Handbook
¥ Completing the course with the same vaccine brand is preferred.
There are currently 2 vaccines available on the private market for the protection of Meningococcal B disease.
- Bexsero® – For use from 6 weeks of age
- Trumenba® – For use in ≥10 years of age
These vaccines can be administered at the same time as routine NIP vaccines (Refer to advice below on paracetamol in infants <4-years)
Meningococcal B vaccines brands are not interchangeable.
The RCH and Monash Immunisation services recommend the use of paracetamol with every dose of 4CMenB given to children <4-years of age, to reduce the likelihood and severity of fever that may occur after immunisation with 4CMenB. The first dose of paracetamol (15 mg/kg per dose) should be given in the 30 minutes before vaccination, or as soon as possible after immunisation, even if children do not have a fever. This should be followed by 2 more doses of paracetamol given 4 to 6 hours apart.

|Vaccine Brand¥||Course commenced at age 6 weeks to ≤5 months||Course commenced at 6 months to ≤11 months||Course commenced at 12 months to ≤ 9 years of age||Course commenced at ≥10 years of age|

#Paracetamol recommended to those <4 years of age (refer to advice above)

Special risk groups
Certain medical conditions and taking some medications can pre-dispose individuals to Meningococcal disease. The list below outlines examples of patient groups who would be considered high risk.
- Complement deficiency (including factor H, factor D or properdin deficiency)
- Eculizumab (anti-C5 antibody: eg- HUS)
These patients are recommended to receive protection against Meningococal B and A, C, W, and Y based on the schedule below.

Welcome to MVEC
The Melbourne Vaccine Education Centre (MVEC) is a new web-based initiative, providing up-to-date immunisation information for healthcare professionals, parents and the public.
It is a collaboration between The Royal Children’s Hospital (RCH) and its Melbourne Children’s campus partners (Murdoch Children's Research Institute and The University of Melbourne) and Monash Health.
MVEC aims to address common queries around vaccines and to promote the benefits of immunisation for both children and adults.
