Sanofi and GSK have announced that they have signed a letter of intent to develop an adjuvanted vaccine for COVID-19, using innovative technology from both companies, to help address the ongoing pandemic.

Sanofi will contribute its S-protein COVID-19 antigen, which is based on recombinant DNA technology. This technology has produced an exact genetic match to proteins found on the surface of the virus, and the DNA sequence encoding this antigen has been combined into the DNA of the baculovirus expression platform, the basis of Sanofi’s licensed recombinant influenza product in the US.

GSK will contribute its proven pandemic adjuvant technology. The use of an adjuvant can be of particular importance in a pandemic situation since it may reduce the amount of vaccine protein required per dose, allowing more vaccine doses to be produced and therefore contributing to protect more people. 

The companies have set up a Joint Task Force, co-chaired by David Loew, Global Head of Vaccines, Sanofi and Roger Connor, President Vaccines, GSK. The taskforce will seek to mobilize resources from both companies to look for every opportunity to accelerate the development of the candidate vaccine.
