1 Using Systems Vaccinology to Elucidate the Effects of Anti-inflammatory Therapy on Immune Response After Vaccination With a Live Attenuated Vaccine

Since the 1st pandemic of the 21st century caused by SARS coronavirus, the world has experienced outbreaks of swine origin H1N1 influenza, Ebola and Zika viruses, which have all resulted in global health crises. Rapid mass vaccination with an effective vaccine such as a live attenuated vaccine, of vulnerable immune-naïve populations to establish herd immunity is an approach to control outbreaks. Such live attenuated vaccine had been used with great success in sporadic yellow fever outbreaks and recently successfully employed in Ebola field trial, both of these diseases have the potential for pandemic spread. Indeed, live attenuated vaccines have proven especially effective in controlling childhood diseases and have even succeeded in eradicating polio and measles from most parts of the world. However, deployment of such vaccines for pandemic control cannot be limited to children but must include adults in order to rapidly elevate herd immunity rates to halt transmission. Vaccinating adults may produce efficacy rates significantly different to those observed in children due to the prevalence of chronic diseases and their associated metabolic complications. Presently, there are 1 billion people who are overweight, many suffer from concurrent metabolic disorders. As activation of the adaptive immunity is reliant on a robust innate immune response to vaccines, metabolic disorders and long-term anti-inflammatory therapy with interventions such as statins may reduce vaccine immunogenicity resulting in suboptimal efficacy in this subpopulation. This study would therefore test the hypothesis that statins reduce live attenuated vaccine immunogenicity. We will combine a clinical trial with systems vaccinology approaches to define the impact statins has on the innate immune, B and T-cell responses to live attenuated vaccination. Our study will thus extend upon another recently completed trial by us and will provide new insights into the determinants of vaccine efficacy in a rapidly growing and aging population globally

2 A Phase 1b Double-blind, Placebo-controlled, Dose-ranging Study to Evaluate the Safety, Pharmacokinetics, and Anti-viral Effects of Galidesivir Administered Via Intravenous Infusion to Subjects With Yellow Fever or COVID-19

This is a placebo-controlled, randomized, double-blind study to evaluate the pharmacokinetics, safety and antiviral activity of galidesivir in subjects with yellow fever (YF) or COVID-19.

3 COVID-19 Response - Thermography Based Fever Detection for Triaging of Patients - A Feasibility Study

This study will refine and pilot the feasibility of introducing a thermal imaging test to detect fever in 100 patients being triaged within the Emergency Department. The only additional research requirement for the patient is to have a thermal image of their face taken. Other triage tests will be routine. The aims of the feasibility study are to: - Understand the acceptability of introducing the intervention within the Emergency Department setting - Establish indicative patient recruitment numbers per week - Determine the likely proportion of patients recruited from this group who have a high temperature - Provide preliminary evidence that the technology can identify a high temperature in this diverse group of patients - Provide preliminary data for machine learning training to support classification of patients as being with or without fever The feasibility study will then inform the design and size of larger study to further develop and validate the the thermal imaging screening test to provide a 'with/ without' fever result.
