NEW YORK—Time flies, even when you’re not having fun it turns out. Yes, it has been more than a year now since the coronavirus first arrived in the U.S. And, according to research, it seems there are signs of growing public dissatisfaction with the country’s response to the pandemic.

Performance ratings for how top health and state and local officials have responded to the outbreak continue to decline, according to a recent Pew Research post.

And there’s even less consensus now than there was a year ago about whether certain steps, like restrictions on restaurants, are necessary.

Yet, as COVID-19 vaccine production and safety efforts in the U.S. continue to ramp up, a new Pew Research survey finds public intent to get vaccinated also is on the rise.

Overall, 19 percent of adults say they have already received at least one dose of a coronavirus vaccine, Pew Research reports. Another 50 percent say they definitely or probably plan to get vaccinated. Taken together, 69 percent of the public intends to get a vaccine—or already has—a marked increase from 60 percent who said they planned to get vaccinated in November.

Differences across demographic and political groups continue to characterize public views of COVID-19 vaccines. Yet these dynamics are fluid, and there have been some notable changes as intent has risen and vaccines become more widely available in the U.S., according to Pew Research.

• A majority of Black Americans (61 percent) now say they plan to get a COVID-19 vaccine or have already received one, up sharply from 42 percent who said they planned to get vaccinated in November.

• Among older adults—who are at greater risk of a serious case of the disease and have priority access to vaccines in most places—41 percent say they have already received at least one dose; another 44 percent say they definitely or probably plan to get vaccinated.

• People with lower income levels continue to be less inclined than those with higher incomes to get a vaccine, a dynamic that is borne out in the shares who say they have already received a COVID-19 vaccine: 14 percent of lower-income adults say they have gotten at least one dose of a vaccine, compared with 20 percent of middle-income adults and 27 percent of upper-income adults.

• A smaller majority of women (66 percent) than men (72 percent) intend to get a vaccine or have already received at least one dose. Among those not planning to get vaccinated, women are more likely than men to cite concerns about the rapid pace of vaccine development and a lack of information about how well they work.

Those who do not currently plan to get a vaccine (30 percent of the public) list a range of reasons why. Majorities cite concerns about side effects (72 percent), a sense that vaccines were developed and tested too quickly (67 percent) and a desire to know more about how well they work (61 percent) as major reasons why they do not intend to get vaccinated.

Smaller shares of those not planning to get a vaccine say past mistakes by the medical care system (46 percent) or a sense they don’t need it (42 percent) are major reasons why they don’t plan to get a vaccine; 36 percent of this group (11 percent of all U.S. adults) say a major reason they would pass on receiving a coronavirus vaccine is that they don’t get vaccines generally.
