Filter by:This study aims to implement a targeted 4CMenB immunisation program in young people aged 14-19 years in the Northern Territory (NT). As part of the NT program consenting 14-19 year olds will receive 2 doses of the licensed 4CMenB vaccine. An oropharyngeal swab will be collected on the same day as the first dose of the vaccine and 12 months later to assess carriage of Neisseria meningitidis. The first swab will assess baseline carriage prevalence among 14-19 year olds in the NT. The swab taken 12 months later will provide data on the change in carriage that may occur after implementation of the immunisation program. Emerging evidence suggests that the 4CMenB vaccine may be protective against gonorrhea. Therefore, vaccine effect (impact and effectiveness) against both invasive meningococcal disease (IMD) and gonorrhea in the NT will be assessed using data from the above study comparing notifications between vaccinated and unvaccinated as well as comparing pre and post implementation periods.
The need for and timing of booster doses of meningococcal vaccines in People Living with HIV (PLWHIV) is currently unknown. As such it is impossible for clinicians to recommend booster doses or to know if and when these might be necessary.We propose to follow up a group of participants from the Propositive study who received two doses of both MenB (Bexsero) and MenACWY (Menveo). This was a group of PLWHIV between the ages 18-45 years. We propose following up these participants at 18 and 30 months post completion of two doses of vaccine and investigating their immunological response.
This study is designed to allow cord blood sample collection from the cords of babies born in three gestational age windows: ≥37 gestational weeks, 32-36+6 gestational weeks and less than 32 gestational weeks to investigate whether the result obtained using a standard hSBA assay is comparable to that achieved using complement from a gestation matched population for meningococcal B and pertussis.
