- Change Research surveyed 1,775 respondents for CNBC from Aug. 30 to Sept. 2 about Americans' views on Covid vaccines, President Joe Biden, former President Donald Trump and other issues.
- Among the 29% of U.S. voters who are unvaccinated, 83% say they do not plan to get the lifesaving shots, the survey shows.
- Growing vaccine hesitancy could make it difficult to reach the up to 90% vaccination rate that some health officials have suggested is necessary to achieve nationwide herd immunity to Covid.
Americans who are unvaccinated against Covid-19 are largely driven by a mistrust of the government and fears over vaccine side effects, and there is very little that can be done to persuade them to get the shots, a new CNBC/Change Research poll reveals.
Change Research surveyed 1,775 respondents for CNBC from Aug. 30 to Sept. 2 about Americans' views on Covid vaccines, President Joe Biden, former President Donald Trump and other issues.
Among the 29% of U.S. voters who are unvaccinated, 83% say they do not plan to get the lifesaving shots, the survey shows. A frustrated Biden on Thursday outlined a host of new vaccine and testing mandates for federal workers and contractors as well as health-care and private company employees.
"What more is there to wait for? What more do you need to see? We've made vaccinations free, safe and convenient. The vaccine has FDA approval, over 200 million Americans have gotten at least one shot," Biden said. "We've been patient, but our patience is wearing thin, and the refusal has cost all of us. So please do the right thing."
Of the unvaccinated respondents, 84% said their decision against immunization wouldn't change if the vaccines had no side effects and 87% said they still wouldn't get the shots if their employer mandated them. Just 5% and 4% of respondents, respectively, said those things would make them "much more likely" to change their minds, the survey shows. Pressure from family members made little difference, with just 2% saying that would make them much more likely to get the shots.
Growing vaccine hesitancy could make it difficult to reach the up to 90% vaccination rate that some health officials have suggested is necessary to achieve nationwide herd immunity to Covid.
"It's time for people to understand that there's no herd immunity in sight that is going to allow this virus to go away and not come back," Dr. Bruce Farber, chief of infectious disease at Northwell Health in New York, told CNBC in a Sept. 1 interview. "And we are going to be living with this virus just the way we live with influenza for the foreseeable future."
Some 34% of unvaccinated respondents said they were hesitant to get the shots because they didn't trust the federal government, while another 34% were worried about the vaccine's side effects. Less than 10% of unvaccinated respondents said they would be more likely to get vaccinated if the delta variant were more problematic in their community, and 7% said they would get vaccinated if asked by Trump.
"There does appear to be something specific to COVID-19 at work as well, because 56% of the unvaccinated report having received a flu shot in the past," the poll said.
The divide between the vaccinated and unvaccinated was especially apparent along political lines. Among unvaccinated voters polled by Change Research, 87% said they voted for Trump. Some 60% said they were Republican.
Among vaccinated voters, 68% said they backed Biden in 2020. About half of vaccinated voters said they were Democrats, the survey showed.
The survey found that 53% of unvaccinated respondents said they were less likely to get the shots after top U.S. health officials endorsed Covid booster shots on Aug. 18 for mRNA vaccines because that protection decreases over time. But 73% of vaccinated voters said they would eventually receive their third doses.
Despite their resistance to immunizing against Covid, unvaccinated respondents appeared more willing to embrace therapeutic treatments if recommended by a doctor following a positive Covid diagnosis. The poll found that 44% of unvaccinated voters responded "maybe" when asked whether they would accept either an intravenous antiviral or monoclonal antibodies, compared with 33% of unvaccinated respondents who said they would reject the antibodies and 34% who would refuse the antiviral.
With students returning to in-person learning and employers bringing their staff back into the office, the poll also captured voters' thoughts on mask requirements in schools and vaccine mandates in the workplace. Among parents of children under 18, 51% support mask mandates for faculty, while 47% think schools should make students wear facial coverings.
The poll reported stronger support for employer vaccine mandates, with 55% of voters agreeing with inoculation requirements for staff at private businesses. And 67% of respondents said companies should be allowed to enforce mask requirements for customers.
"One of the things that was most likely to lead someone to get vaccinated was if their employer required it," the poll found.
CORRECTION: This story was updated to correct how vaccinated and unvaccinated people voted. Among unvaccinated voters, 87% said they voted for Trump. Among vaccinated voters, 68% said they voted for Biden.
