Study to Assess Oropharyngeal Carriage of N. Meningitidis in South Australian School Leavers (B Part Of It)
10 oktober 2021 uppdaterad av: Helen Marshall, University of Adelaide
An Observational Cross-sectional Study to Assess Oropharyngeal Carriage of N. Meningitidis in South Australian School Leavers
This is an observational cross sectional study to evaluate the impact of a 4CMenB vaccination program on oropharyngeal N. meningitidis carriage in vaccinated and unvaccinated school leavers.

Detaljerad beskrivning
This carriage study of a cohort of school leavers in South Australia (SA) will provide an opportunity to assess carriage rates in the young adult population (school leavers) following introduction of a 4CMenB vaccination program in senior school students from 2017-2018.This will allow a comparison of carriage prevalence in the two years (2018 and 2019) following implementation of the school program to assess impact on carriage at a population level and compare carriage prevalence in vaccinated versus non-vaccinated groups. Assessment of any association between risk factors and prevalence of nasopharyngeal carriage in school leavers will be made and compared between vaccinated and unvaccinated students.
School leavers are defined as students who were enrolled in year 12 at school in the preceding year of recruitment and have been chosen as they are likely to have the highest carriage rates. A high proportion (approximately two thirds) of students will be immunised by the time of throat swab collection in years 2018 and 2019. Assessing carriage in both vaccinated and unvaccinated cohorts will further inform the effect of 4CMenB vaccine on carriage at a population level. This will help determine any herd immunity impact of 4CMenB vaccine and persistence of any effect.
