Why Americans have grown more hesitant about the COVID-19 vaccine

Facing a virus that has already sickened millions of people around the globe — including the president of the United States — and killed above a million more, public health experts regard a vaccine as the one thing that can help the planet regain control and restore a semblance of normality.

But the number of U.S. adults who say they would get vaccinated against COVID-19 has slipped significantly since August, when 60 percent of people surveyed in a PBS NewsHour/NPR/Marist poll were willing. On Sept. 18, just 49 percent of Americans said they would get vaccinated against COVID-19, while another 44 percent said they would not.
