« Proof of solidarity »

Sanofi had already agreed to manufacture from the summer, in its German factory in Frankfurt, more than 125 million doses of the messenger RNA vaccine developed by Pfizer-BioNTech.

The urgency of the pandemic has given rise to unexpected alliances between companies in the sector. The Swiss Novartis, which is not launched in the vaccine race, is also preparing to produce for BioNTech.

For Sanofi CEO Paul Hudson, this agreement with Johnson & Johnson ” shows Sanofi’s determination to contribute to the collective effort to end this health crisis as quickly as possible “And to do” proof of solidarity ».

« Our top priority: manufacturing our own vaccine »

These nudges come after the French government asked Sanofi to make its production lines available to speed up the availability of doses, eagerly awaited in an attempt to curb a pandemic that has killed nearly 2.5 million people in the world.

« Our top priority remains the manufacture of our own vaccine. If we do this operation with BioNTech or Johnson & Johnson, it’s because we made sure that we also have the capacity to produce our own vaccine. », Insisted Thomas Triomphe.

« Refined formulation »

Because if it suffered setbacks, the French laboratory is determined to succeed. He also announced on Monday that he was starting a new clinical study called ” phase 2 »Of its main vaccine candidate developed with the British GSK and using recombinant protein technology. The French pharmaceutical firm hopes to make it available in the fourth quarter. It was originally scheduled for summer 2021.

« This new phase 2 study will assess the potential of a refined formulation of antigens to achieve an optimal immune response, particularly in older adults », Explains Thomas Triomphe.

The previous phase 1/2 study concluded in December of an insufficient immune response in older adults, ” presumably due to insufficient concentration of antigens ».
