The majority of Americans are waiting for the arrival of a COVID-19 vaccine before they feel comfortable returning to the bleachers, according to a study conducted this past weekend.

Two-thirds of the survey respondents said they would not attend an indoor sporting event without a vaccine -- even if masks and social distancing measures were being enforced.

The survey, conducted by Seton Hall University's Sharkey Institute, collected answers from 1,506 adults from across the country. The responses were collected from Nov. 13 through Nov. 16 -- roughly one week after Pfizer announced that an early trial showed it had developed a COVID-19 vaccine that was more than 90% effective.
