A national NPR/PBS NewsHour/Marist poll released Wednesday found that although a 61 percent majority of GOP men said they would take the vaccine, only 34 percent GOP women agreed. Democratic women also appeared to be more reluctant than their male counterparts, although both were more likely to agree than Republicans, with 85 percent of men and 70 percent of women saying they would choose to be vaccinated.

However, a 71 percent majority of Independent women said they would take the vaccine, more than the 62 percent of Independent men who agreed. Regardless of gender, similar numbers of Independents, 5 to 6 percent, were uncertain of their choice. Republican and Democratic women were less certain. GOP women who said they were not sure numbered 10 percent, compared to 5 percent of men, while 13 percent of Democratic women and no Democratic men were uncertain.

The poll found that 61 percent of adults were willing to take the vaccine overall, with 32 percent unwilling and another 7 percent undecided. A previous edition of the same poll conducted in September found that only 49 percent were willing, while 35 percent were not and 5 percent were unsure. Wednesday’s poll was conducted among 1,065 U.S. adults between December 1 and December 6, with a margin of error of 3.7 percent.
