Objectives & strategy

Objectives and strategy

PREVAC-UP is built around PREVAC and will extend the work initiated by the consortium. The objectives of the projects are:


To determine the safety and the immunogenicity of three Ebola vaccine strategies up to 5 years after vaccination of the participants included under version 4 of PREVAC


To use an integrative statistical analysis of the immune response to explore the mechanism of action of the vaccines and to identify early correlates of durable antibody induction.


To assess the durability of humoral and cellular immune response of these strategies up to 5 years after vaccination



To build on the extensive community mobilisation efforts established during PREVAC and provide a trans-national platform for social science research.


To evaluate the effect of common parasitic infections, including malaria and helminths, on the durability of the immune response to Ebola vaccination


To expand and sustain capacity building and training of scientists in the four participant African countries that have been initiated in the PREVAC trial.

To achieve its goals, the project in divided on 6 scientific work packages and a management/communication work package.

PREVAC-UP project is funded by the European and Developing Countries Clinical Trials Partnership (EDCTP2) programme supported by the European Union. PREVAC-UP also benefits from co-funding from Inserm, the NIAID, the LSHTM and the COMAHS as well as host country support from Liberia, Sierra Leone, Guinea and Mali.
