Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

History of febrile convulsions should not lead to exclusion.
9. Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study.

11. Previous vaccination against any group B meningococcal vaccine at any time prior to informed consent and assent as applicable (according to the participant's age).
12. Previous vaccination with 2 or more doses of MenACWY vaccine.
13. Administration/planned administration of immunoglobulins and/or any blood products or plasma derivatives during the period starting 3 months before any dose of study vaccine(s)/product until the following post-vaccination blood sample.
14. Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting 3 months prior to any vaccine/product dose until the following post-vaccination blood sample. For corticosteroids, this will mean prednisone equivalent =20 mg/day for adult participants and =0.5 mg/kg/day with maximum =20 mg/day for pediatric participants. Inhaled and topical steroids are allowed.
15. Concurrently participating in another clinical study, at any time during the study period, in which the participant has been or will be exposed to an investigational or a non investigational vaccine/product (drug or medical device).
16. Child in care.
17. Pregnant or lactating female.
18. Female planning to become pregnant or planning to discontinue contraceptive precautions.
