Staff reports | European pharmaceutical companies Sanofi and GSK on Wednesday announced promising results from clinical trials for a new two-dose COVID-19 vaccine with 100% efficacy against severe disease and hospitalizations, according to a report from The New York Times.

The new vaccine, one of four to receive funding from the Trump administration’s Operation Warp Speed program, also showed a 75% efficacy rate against moderate to severe illness, and 58% efficacy against symptomatic disease in its Phase 3 clinical trial. The results are in line with expected effectiveness, according to a statement, but it is lower than results from initial Pfizer and Moderna trials. 

The Sanofi and GSK vaccine uses a more conventional approach to vaccination, targeting the protein that covers the surface of the virus, rather than the newer mRNA vaccines. Manufacturers hope the familiar approach may persuade some who have been hesitant to adopt the newer mRNA vaccine methodology. 

Data has not yet been published, but a statement from the companies said the vaccine was safe and well-tolerated by adults of all ages. And when used as an extra dose after another available coronavirus vaccines as a booster shot, it increased antibody levels by 18- to 30-fold.
