the vaccine against Covid-19 is ready

This is news that we were almost expecting. After dosing and then timing problems, the Sanofi vaccine is ready. It must now find its place among its well-established competitors. The major innovation of this new vaccine? Its technology: recombinant protein. A way to convince people who are skeptical of messenger RNA. “It is not an RNA vaccine, it is a vaccine in which only what is called recombinant protein has been used, a very sophisticated technology mastered by few laboratories“, explains Professor Jean-François Saluzzo, expert in virology with the WHO.

According to Sanofi, this vaccine would be 100% effective against severe forms, 75% against moderate forms and 58% against any asymptomatic form. It would also make it possible to systematically avoid hospitalizations linked to Covid-19, but would be ineffective against the Omicron variant. One year after the date initially hoped for, Sanofi will seek approval for its vaccine from the authorities of the United States and the European Union.
