Optimizing mood prior to influenza vaccination in older adults: A three-arm randomized controlled trial (2023)
Journal Article

Objective: This trial explored the psychological and immunological effects of two brief interventions, targeting improving positive mood, administered to older adults immediately prior to influenza vaccination. The primary aim was to examine whether... Read More about Optimizing mood prior to influenza vaccination in older adults: A three-arm randomized controlled trial.

Reactogenicity, immunogenicity and breakthrough infections following heterologous or fractional second dose COVID-19 vaccination in adolescents (Com-COV3): A randomised controlled trial (2023)
Journal Article

Background: This was the first study to investigate the reactogenicity and immunogenicity of heterologous or fractional second dose COVID-19 vaccine regimens in adolescents. Methods: A phase II, single-blind, multi-centre, randomised-controlled trial...

Persistence of immune response in heterologous COVID vaccination schedules in the Com-COV2 study – A single-blind, randomised trial incorporating mRNA, viral-vector and protein-adjuvant vaccines (2023)
Journal Article

Background: Heterologous COVID vaccine priming schedules are immunogenic and effective. This report aims to understand the persistence of immune response to the viral vectored, mRNA and protein-based COVID-19 vaccine platforms used in homologous and... Read More about Persistence of immune response in heterologous COVID vaccination schedules in the Com-COV2 study – A single-blind, randomised trial incorporating mRNA, viral-vector and protein-adjuvant vaccines.

Variable disruption of epithelial monolayers by Neisseria meningitidis carriage isolates of the hypervirulent MenW cc11 and MenY cc23 lineages (2023)
Journal Article

Colonization of mucosal tissues by Neisseria meningitidis requires adhesion mediated by the type IV pilus and multiple outer-membrane proteins. Penetration of the mucosa and invasion of epithelial cells are thought to contribute to host persistence a... Read More about Variable disruption of epithelial monolayers by Neisseria meningitidis carriage isolates of the hypervirulent MenW cc11 and MenY cc23 lineages.

Impact of meningococcal ACWY conjugate vaccines on pharyngeal carriage in adolescents: evidence for herd protection from the UK MenACWY programme (2022)
Journal Article

Objective: Serogroup W and Y invasive meningococcal disease increased globally from 2000 onwards. Responding to a rapid increase in serogroup W clonal complex 11 (W:cc11) invasive meningococcal disease, the UK replaced an adolescent booster dose of m...

Safety and immunogenicity of heterologous versus homologous prime-boost schedules with an adenoviral vectored and mRNA COVID-19 vaccine (Com-COV): a single-blind, randomised, non-inferiority trial (2021)
Journal Article

Background: Use of heterologous prime-boost COVID-19 vaccine schedules could facilitate mass COVID-19 immunisation. However, we have previously reported that heterologous schedules incorporating an adenoviral vectored vaccine (ChAdOx1 nCoV-19, AstraZ...

Rapid Transmission of a Hyper-Virulent Meningococcal Clone Due to High Effective Contact Numbers and Super Spreaders (2020)
Journal Article

© Copyright © 2020 Holmes, Green, Oldfield, Turner and Bayliss. Rapid transmission, a critical contributory factor in outbreaks of invasive meningococcal disease, requires naïve populations of sufficient size and intermingling. We examined genomic va...

Localized hypermutation is the major driver of meningococcal genetic variability during persistent asymptomatic carriage (2020)
Journal Article

© 2020 Green et al. Host persistence of bacteria is facilitated by mutational and recombina-torial processes that counteract loss of genetic variation during transmission and selection from evolving host responses. Genetic variation was investigated... Read More about Localized hypermutation is the major driver of meningococcal genetic variability during persistent asymptomatic carriage.

Localized Hypermutation is the Major Driver of Meningococcal Genetic Variability during Persistent Asymptomatic Carriage (2020)
Journal Article

Host persistence of bacteria is facilitated by mutational and recombina-torial processes that counteract loss of genetic variation during transmission and selection from evolving host responses. Genetic variation was investigated during persistent as... Read More about Localized Hypermutation is the Major Driver of Meningococcal Genetic Variability during Persistent Asymptomatic Carriage.

The moonlighting peroxiredoxin-glutaredoxin in Neisseria meningitidis binds plasminogen via a C-terminal lysine residue and contributes to survival in a whole blood model (2019)
Journal Article

© 2019 Elsevier Ltd Neisseria meningitidis is a human-restricted bacterium that can invade the bloodstream and cross the blood-brain barrier resulting in life-threatening sepsis and meningitis. Meningococci express a cytoplasmic peroxiredoxin-glutare...

Potentiation of phase variation in multiple outer membrane proteins during spread of the hyperinvasive Neisseria meningitidis serogroup W ST-11 lineage (2019)
Journal Article

BACKGROUND: Since 2009, increases in invasive meningococcal disease have occurred in the United Kingdom due to a sub-lineage of the Neisseria meningitidis serogroup W ST-11 clonal complex (the 'original-UK' strain). In 2013, a descendent sub-strain...

Limited impact of adolescent meningococcal ACWY vaccination on Neisseria meningitides serogroup W carriage in university students (2017)
Journal Article

Background In the UK rising disease levels due to Neisseria meningitidis serogroup W clonal complex ST-11 (MenW:cc11) strains led to introduction of conjugate MenACWY vaccination for teenagers. We investigated the impact of immunization on carriag...
