GSK and Sanofi to start human trials of potential Covid-19 vaccine

GlaxoSmithKline and Sanofi are to start testing their protein-based Covid-19 vaccine on humans for the first time, following promising results in earlier studies. GSK, the world’s largest vaccine maker, and the French drugmaker Sanofi joined forces in April to work on an effective treatment to halt the devastating pandemic. The vaccine being developed by London-headquartered GSK and Paris-based Sanofi combines existing technology used by Sanofi to make its flu vaccine, along with an add-on from GSK, known as an adjuvant, which can be mixed with a vaccine to trigger a stronger immune reaction.
