A person's 2020 presidential vote is proving the biggest indicator of whether or not they want a coronavirus vaccine.

People who supported President-elect Joe Biden in November are overwhelmingly in favor of getting the COVID-19 vaccine, with 79 percent saying they want it and 4 percent saying they've already gotten it, an NPR/PBS Newshour/Marist poll out Tuesday shows. Meanwhile just 39 percent of voters who backed President Trump say they want the vaccine and a similar 4 percent have already gotten it.

Marist asked adults whether they'd get a COVID-19 vaccine if it was made available to them. Support for getting the vaccine was clearly divided along party lines, with 75 percent of Democrats saying they wanted the vaccine but just 43 percent of Republicans saying the same. Democratic men were the most likely of any demographic — race, region, income, education, age, or generation — to want the vaccine, at 85 percent. Meanwhile the smallest percentage of adults who said they wanted the vaccine were Trump voters.

Also among groups who had a low percentage of vaccine support were Gen Xers — just 49 percent of Americans age 40-55 want the vaccine, the poll found. Republican women and people who live in small towns were not very likely to want the vaccine, with just 41 and 51 percent saying they would like it, respectively. Trump has so far not publicly said if he has gotten the vaccine, but has underplayed the seriousness of the virus for the past year.

Marist surveyed 1,173 American adults from Jan. 11–13 via landline and mobile phone, with a margin of error of 3.5 percentage points.
