contains 4 µg each of serogroups A, C, W 135 and Y polysaccharides<br />

conjugated with a total of approximately 48 µg of a diphtheria toxoid<br />

protein.<br />

• Menveo – CSL Limited/Novartis Vaccines and Diagnostics Pty<br />

Ltd (meningococcal serogroups A, C, W 135 , Y–CRM 197 conjugate).<br />

Lyophilised powder containing serogroup A (MenA) in a monodose<br />

vial with a pre-filled syringe or vial containing serogroups C, W 135 and<br />

Y (MenCWY) in saline suspension. Each 0.5 mL reconstituted dose<br />

contains 10 µg of serogroup A and 5 µg each of serogroups C, W 135<br />

and Y oligosaccharides individually conjugated with up to 33.3 µg of<br />

non-toxic C. diphtheriae CRM 197 protein; sucrose.<br />

All conjugate vaccines induce immunity within 10 to 14 days of administration.<br />

MenCCVs confer protection only against serogroup C disease. 4vMenCVs will<br />

provide protection against four serogroups of meningococci: serogroups A, C,<br />

W and Y. Neither MenCCV nor 4vMenCV will provide protection against<br />

135<br />

serogroup B meningococcal disease.<br />

MenCCVs have been used in an infant schedule in many countries, including<br />

Australia. 11-13,17-19 <strong>The</strong> vaccine effectiveness following 1 dose of MenCCV has<br />

been estimated to range from 83 to 100%. 13,17 <strong>The</strong>re has been a sustained decline<br />

in serogroup C meningococcal disease, which has also been observed in age<br />

groups not targeted in vaccination programs, both in Australia and overseas. 11,14<br />

Duration of immunity is still uncertain. However, current serogroup C<br />

meningococcal disease epidemiology in Australia suggests ongoing protection in<br />

those groups previously vaccinated. 11<br />

Hib-MenCCV can be administered where a booster dose of H. influenzae<br />

type b and primary vaccination for meningococcal serogroup C is required.<br />

<strong>The</strong> immunogenicity and safety of Hib-MenCCV as a booster dose has been<br />

demonstrated in clinical trials and in the United Kingdom, where this vaccine is<br />

now administered as part of the infant schedule. 20-25<br />

Several clinical trials have demonstrated the immunogenicity of 4vMenCV,<br />

with human serum bactericidal assay titres of ≥1:4 reported in adolescents and<br />

young adults. 26-28 <strong>The</strong>re have been a number of studies examining 4vMenCV in<br />

children. 29-31 All studies indicated that 4vMenCVs were safe and immunogenic in<br />

both infants and children. 29-33 Menveo has demonstrated superiority to Menactra<br />

in serum bactericidal assays to serogroups A, W and Y (and variably also to<br />

135<br />

serogroup C); however, the clinical relevance of this is currently unknown. 27,34-36<br />
