Their results confirm the value of using a synthetic STxB in an anti-tumor and anti-infectious vaccination strategy.

They observed a strong response to the viral nucleoprotein (NP) and suggest that components of NP may be included in the design of new Ebola vaccines.

They identified one of them as being the most effective, likely to quickly enter clinical trials in humans. Results are published in the journal Science Translational Medicine. Vaccine Scientific result Wed, 09 Oct 2019 10:00:00 GMT https://www.cea.fr/drf/joliot/en/Pages/news/Science/2018/spectrometry-quality-control-vaccines.aspx ​A SPI Research Team (LI2D, Marcoule), in collaboration with CIRAD and AU-PANVAC, proposes a new quality control technique for veterinary vaccines, based on very high resolution mass spectrometry. This strategy, based on the use of an ad hoc database to measure the proportion of antigens and contaminants in the vaccine preparation, will improve the quality control of vaccines against contagious caprine pleuropneumonia.

This mission is is concluded by the signing of a framework agreement between the two institutes in the field of therapeutic and vaccine innovation.
