12 May 2020 --- The Lallemand group is partnering with Canadian companies Biotechnologies Ulysse and Bio-K Plus to develop a vaccine against COVID-19. The vaccine could contain live bacteria and yeast that have the same properties as the virus, but without the contagious load of COVID-19. Biotechnologies Ulysse is working on a proof of concept, hoping to start testing the vaccine in animals within four to six weeks, and to have obtained the first preclinical results in around four to five months.
