The U.S. presidential election is a big factor, particularly after President Donald Trump’s refusal Wednesday to commit to a peaceful transition of power if he lost, and rising tensions between the United States and China. Adding to the uncertainty is the question of how soon drug makers will be able to develop a coronavirus vaccine to stem future waves of outbreaks.
