LE FIGARO. – What products have you tried?
Odile LAUNAY. – We compared the Pfizer/BioNTech vaccine, which is already on the market, with two Sanofi-GSK products that are currently being validated by health authorities. This is a more traditional technology than messenger RNA, known as “recombinant proteins”. In summary, Sanofi produces growths of the virus in bioreactors (proteins that form small spikes on its surface, editor’s note) which will serve as targets for the immune system to learn. And to stimulate the body’s response and attract immune cells to the injection site, the company combines them with an adjuvant produced by its partner GSK. Sanofi produced two types of strains, the original Wuhan virus and the Beta version. (originally called “South African version”). This produces two separate vaccines, one containing only Wuhan spikes and the other a mixture of spikes from both variants.
