About This Seminar

This webinar will explore the feasibility of conducting a phase III vaccine trial for a CCHFV-specific vaccine. Through mathematical models, we will estimate key trial design components such as sample size and time to attain the necessary number of trial endpoints in three different endemic settings: Afghanistan, South Africa, and Turkey.

Crimean-Congo Haemorrhagic Fever (CCHF) virus (CCHFV) is a zoonotic tick-borne emerging pathogen that can lead to fatal haemorrhagic fever in humans. Despite this, no effective vaccine formulation is currently available, while the epidemiological map of influence for CCHFV keeps expanding.

Key Topics

Feasibility of conducting phase III vaccine trials for CCHFV

Mathematical modeling for trial design

Sample size estimation for vaccine trials

Time to endpoint analysis

Comparative analysis across endemic settings

Seminar Details

Dr. Juan Vesga is a Lead Infectious Disease and Vaccine Modeller at the UK Health Security Agency and a visiting researcher at Imperial College London. His work focuses on using mathematical models to understand disease dynamics of preventable diseases and the impact of interventions. His research on CCHF was developed during his time at the London School of Hygiene and Tropical Medicine, where he also developed models for tick-borne diseases like Lyme Disease and Tick-borne Encephalitis.

Using Mathematical Models to Explore Future Meningitis Vaccination Strategies in Ghana

Vaccination has been a useful tool in the control of meningitis in Ghana. MenAfriVac, a conjugate vaccine against meningococcal serogroup A (MenA) has contributed to a drastic decline in serogroup A epidemics. This targeted 1–29-year-olds in 2012 with a subsequent nationwide routine immunization of 18-month-olds in 2016. However, cases due to other serogroups of meningococcus remain a public health concern in Ghana.
