That could have troubling implications. The Biden administration has been touting the booster as a means of warding off a fresh fall or winter surge of the virus.
“America is not rushing out to get the new booster,” said Drew Altman, the president of the Kaiser Family Foundation. “Most are only dimly aware of it, which is not surprising in a country that seems to have mostly moved on.” He added, “The exception may be older folks, who are at greater risk and early on are more interested in the new booster.”
The survey was conducted from Sept. 15 to 26, online and by telephone, among a nationally representative sample of 1,534 adults.

Ever since the first shots were rolled out, people 65 and older, who are the most vulnerable to Covid complications, have been the most compliant with getting the vaccine. They also displayed the broadest awareness of the new booster, the survey found, with almost half reporting either having already received the new dose or aiming to get it “as soon as possible.” Nearly a third of adults overall said they had planned to get it soon as well.
But otherwise, confusion over eligibility seemed widespread, according to the survey.
The Food and Drug Administration authorized the new booster made by Pfizer and BioNTech for fully vaccinated people as young as 12 and the new Moderna booster for those 18 and older. But among fully vaccinated adults 30 and under, 43 percent said they were unsure of whether the dose had been approved for them, and an additional 19 percent said they did not believe it had been.
Dr. Mary Politi, a professor in the Division of Public Health Sciences at the Washington University School of Medicine, said that Americans had been experiencing Covid information overload and, as a consequence, decision-making fatigue. One way to overcome both, she said, “is to keep information simple, clear and consistent.”
She added, “Unfortunately, the information coming from various sources has often been conflicting, with uncertain, unclear or changing guidelines.”
Older adults were also better informed about their booster eligibility status. Among those 65 and older, more than half knew the booster was recommended, as did nearly half of those between the ages of 50 and 64.
While the Centers for Disease Control and Prevention recommends that fully vaccinated people 12 and older get the updated booster, it urges those 50 and older in particular to get it.
The report, which also looked at parents’ views of the vaccine, found that there had been a modest uptick in vaccination among the youngest children since July, when Covid vaccines for those between six months and 4 years old received emergency authorization. At the time, scarcely 7 percent of parents said they intended to get their children vaccinated; that percentage has risen to 19 percent, or nearly one in five parents.
But more parents are refusing the vaccine for their children, too. Now 53 percent of parents of children between six months and 4 years say they will “definitely not” let their children get the shots. Last January, 26 percent held that view.
While some 60 percent of parents said that their children between the ages of 12 and 17 had been vaccinated, about 30 percent of parents with children in that age group said their children would definitely not get the Covid vaccine.
Overall, 77 percent of respondents said they had gotten at least one dose of the Covid vaccine, with nearly half of those saying they had received at least one booster. But 23 percent said they were not vaccinated, and nearly all of that group said they would “definitely not” get it.
