We work with global biotech, pharma, government and NGOs in the design, execution, and commercialisation of vaccines to prevent infectious diseases.

The number of new and re-emerging infectious diseases continues to rise and pose a threat to world health. Our global team have built up extensive vaccine expertise, with over 200 years experience across our leadership team alone. This enables us to anticipate the challenges in your drug development plan and consistently beat aggressive vaccine start up timelines and enrolment goals. We are applying this experience to the COVID-19 vaccine trials we are currently running. We focus on driving your milestone success and on providing high quality deliverables within budget.

Our work has resulted in 18 vaccine approvals by the United States (US) Food and Drug Administration (FDA) and the European Medicines Agency (EMA). And our team have winners of “Best CRO” at the Vaccine Industry Excellence (ViE) Awards three times (2020, 2017 and 2014) and have been named a finalist every year since 2011.

We are also prime contractors for the US Government and qualified provider for the Bill and Melinda Gates Foundation. Our broad portfolio of services and global footprint also serve the needs of other global health organisations such as Wellcome Trust, Global Fund and CEPI.
