PARIS — Production of another potential vaccine against COVID-19 will begin within weeks, its developers Sanofi and GlaxoSmithKline said Thursday as they launched a large Phase III trial enrolling 35,000 adult volunteers in the United States, Asia, Africa and Latin America.

The study will test the effectiveness of vaccine candidate formulas against the virus that spread from Wuhan, China, and against a variant first seen in South Africa, the pharmaceutical firms said.
