Bacille Calmette-Guérin vaccine reprograms human neonatal lipid metabolism in vivo and in vitroVaccines have generally been developed with limited insight into their molecular impact. While systems vaccinology enables characterization of mechanisms of action, these tools have yet to be applied to infants, who are at high risk of infection and receive the most vaccines. Bacille Calmette-GuĂ©rin (BCG) protects infants against disseminated tuberculosis (TB) and TB-unrelated infections via incompletely understood mechanisms.

Multi-Omic Data Integration Allows Baseline Immune Signatures to Predict Hepatitis B Vaccine Response in a Small CohortVaccination remains one of the most effective means of reducing the burden of infectious diseases globally. Improving our understanding of the molecular basis for effective vaccine response is of paramount importance if we are to ensure the success of future vaccine development efforts. We applied cutting edge multi-omics approaches to extensively characterize temporal molecular responses following vaccination with hepatitis B virus (HBV) vaccine. Data were integrated across cellular, epigenomic, transcriptomic, proteomic, and fecal microbiome profiles, and correlated to final HBV antibody titres.

BCG vaccination-induced emergency granulopoiesis provides rapid protection from neonatal sepsisWe found that BCG, in a mouse model of neonatal polymicrobial sepsis, induced granulocyte colony-stimulating factor (G-CSF) within hours of administration
Research
A systems biology approach to better understand human tick-borne diseasesTick-borne diseases are a growing global health concern. Despite extensive studies, ill-defined tick-associated pathologies remain with unknown aetiologies. Human immunological responses after tick bite, and inter-individual variations of immune-response phenotypes, are not well characterised.

The global burden of sore throat and group A Streptococcus pharyngitis: A systematic review and meta-analysisContemporary data for the global burden of sore throat and group A Streptococcus (Strep A) pharyngitis are required to understand the frequency of disease and develop value propositions for Strep A vaccines.

The safety of co-administration of Bacille Calmette-Guérin (BCG) and influenza vaccinesWith the emergence of novel vaccines and new applications for older vaccines, co-administration is increasingly likely. The immunomodulatory effects of BCG could theoretically alter the reactogenicity of co-administered vaccines. Using active surveillance in a randomised controlled trial, we aimed to determine whether co-administration of BCG vaccination changes the safety profile of influenza vaccination.

Vaccination strategies to enhance immunity in neonatesProtection may be further improved by integrating these approaches, namely vaccinating the neonate under the cover of vertically transferred maternal immunity

Dynamic molecular changes during the first week of human life follow a robust developmental trajectorySystems biology and innovative data integration can provide fresh insights into the molecular ontogeny of the first week of life
Research
The non-specific and sex-differential effects of vaccinesThe textbook view of vaccination is that it functions to induce immune memory of the specific pathogen components of the vaccine, leading to a quantitatively and qualitatively better response if the host is exposed to infection with the same pathogen

Maternal HIV infection alters antimicrobial immunity in exposed and uninfected infantsImplementation of lifelong ART of all HIV-infected women has the potential to improve maternal determinants of protective immunity in the young infant
