KFF COVID-19 Vaccine Monitor

An ongoing research project tracking the public’s attitudes and experiences with COVID-19 vaccinations.

Vaccine Trend
uptake and intentions
  • In Their Own Words: Vast Majorities Of Those Who Wanted To Get Vaccinated ASAP Have Received Vaccine, As Have Slightly More Than Half Of Those Who Wanted To "Wait And See"

    Six months after being initially interviewed, the latest Monitor report recontacted individuals and found the vast majority (92%) of those who planned to get vaccinated “as soon as possible” in early 2021 have received at least one dose of a COVID-19 vaccine, as have slightly more than half (54%) of individuals who had previously said they wanted to “wait and see” before getting vaccinated. On the other hand, a majority (76%) of people who had previously said they would “only get vaccinated if required” or said they would “definitely not” get a COVID-19 vaccine remain unvaccinated.

  • In Their Own Words: Most Vaccine Behaviors Match What People Planned To Do Six Months Ago; One In Five Were Either Vaccine Hesitant Or Resistant And Have Gotten Vaccinated

    Half of those who are currently vaccinated had reported back in January 2021 that they either had already received a dose or were planning on getting vaccinated as soon as possible. An additional one in five adults (21%) are now vaccinated after saying in January they planned on waiting to get vaccinated, would only get it if required, or would definitely not get vaccinated. One-third of adults remain unvaccinated after either planning to get it as soon as possible or were going to wait and see back in January (17%) or had said they were only going to get vaccinated if required or were definitely not getting a COVID-19 vaccine (16%).

  • Seven In Ten Adults Eligible For A COVID-19 Booster Dose Have Received One

    The latest Vaccine Monitor finds that similar shares of Black, Hispanic, and White adults now report receiving a COVID-19 booster dose, whether looked at as a share of the total population or among those likely to be eligible for a booster.
    Notably, though younger adults continue to lag older adults and Republicans lag Democrats in the share who say they have gotten a booster dose of a COVID-19 vaccine, among those likely eligible for a booster, majorities across age groups, racial and ethnic groups, and party identification say they have received a booster dose.

  • Feeling They Have Enough Protection And “Just Don’t Want To” Are Among Top Reasons For Not Getting A COVID-19 Booster

    Adults who are eligible for a COVID-19 booster but have not yet received one cite a variety of reasons for not getting a booster. Chief among them is the view that they already have enough protection from either their initial vaccine doses or from a previous COVID-19 infection (56%). Other common reasons these booster-eligible adults say they have not yet gotten a booster include just not wanting to get it (45%), thinking boosters are ineffective because some vaccinated people are still getting infected (39%), and being too busy to go get the shot (33%). About three in ten cite not trusting the government or medical system (29%) or not believing the COVID-19 vaccines are safe (28%) as reasons for not getting a booster. Fewer cite other reasons like side effects from a previous dose (18%), they don’t like getting shots (15%), worries about missing work (8%), difficulties traveling to a vaccination site (7%), or worries about having to pay out of pocket (4%).

Parents and kids
  • One In Five Parents Of Children Under Five Say They'll Vaccinate Their Child Right Away Once Available, But Most Remain More Cautious

    One in five parents of children under 5 (18%) are eager to vaccinate their child and say they will do so right away once a COVID-19 vaccine is authorized for their age group. Almost four in ten parents of children under 5 say they want to “wait and see” before getting their young child vaccinated (38%). Another four in ten parents are more reluctant to get their young child vaccinated with 11% saying they will only do so if they are required and 27% saying they will “definitely not” get their child under 5 vaccinated for COVID-19.

  • About Four In Ten Parents Of Kids Ages 5-11 Say Their Child Has Gotten Vaccinated, But A Third Say They Will "Definitely Not"

    Among parents of 5 to 11 year-olds, who have been eligible for vaccination since October, about four in ten (39%) say their child has gotten vaccinated while a large share say they will either only get their child vaccinated if they are required for school (12%) or say their child will definitely not get the COVID-19 vaccine (32%).

  • Nearly Six In Ten Parents Of Teenagers Say Their Child Is Now Vaccinated, Three In Ten Will Definitely Not Get It

    Most parents of 12 to 17 year-olds say their teenager has been vaccinated (56%, fairly steady since January), while about three in ten (31%) say they will “definitely not” get their teen vaccinated and 4% say they will only do so if they are required.

  • Four In Ten Parents Of Vaccinated Teens Say Their Teen Has Gotten A Booster Shot For COVID-19

    With COVID-19 booster shots approved for children between the ages of 12-17, 40% of parents of vaccinated teenagers report that their teen has received a COVID-19 booster dose. Most parents of vaccinated teenagers say their teen has already gotten a booster dose or that they will definitely (20%) or probably (17%) get one, while about one in five say their teenager will “probably not get” or “definitely not get” a booster shot.

  • Larger Shares Of Parents Of Teens Say Schools Are Providing Them With Information About COVID-19 Vaccines, Encouraging Vaccinations, And Asking About Vaccine Status Than In July

    Among parents of children ages 12-17 who were eligible for vaccination over the summer, the shares who say their child’s school provided information on COVID-19 vaccines, encouraged vaccination, or asked about their child’s vaccination status have all increased since July (from 42% to 52%, 40% to 51%, and 11% to 25%, respectively).

  • Larger Shares Of Parents Who Say Their Child's School Has Encouraged Vaccinating Children Against COVID-19 Have Gotten Their Children Vaccinated

    Parents who say their school has encouraged parents to get their children vaccinated are more likely to say their child has indeed gotten vaccinated when compared to parents whose child’s school has not encouraged vaccination. Among parents of 12-17 year-olds whose school encouraged vaccination, 60% say their teen has already gotten the COVID-19 vaccine, compared to four in ten (42%) of parent who say their teen’s school did not encourage vaccination. Similarly, parents of 5-11 year-olds who say their school encouraged them to get their child vaccinated are four times as likely to say their younger child has already gotten the COVID-19 vaccine than those who say their school did not encourage vaccination.

  • Adults Split On Whether K-12 Schools Should Require COVID-19 Vaccines, With Significant Partisan Divides

    The public is divided on whether K-12 schools should require their staff and eligible students to get a COVID-19 vaccine, with similar shares saying schools should (46%) and should not (51%) require vaccines. Three-fourths of Democrats (76%) say schools should require COVID-19 vaccinations while more than eight in ten Republicans (84%) say schools should not. Independents are more likely to say school should not require COVID-19 vaccines (56%) than to say they should be required (40%). Six in ten parents say schools should not require vaccines including majorities of parents of teens ages 12-17 (58%), children 5 to 11 years old (66%), and children under age 5 (59%).

  • Four In Ten Say All Students And Staff Should be Required To Wear Masks In Schools, Eight In Ten Republicans Oppose Any Mask Requirement

    The scientific debate about mask requirements in schools has received notable attention recently as many school districts ease their masking requirements. Along with concerns over children’s mental health, overall support for masking in K-12 schools has decreased among the public since this past fall. Almost six in ten support any mask requirements in schools including four in ten (43%) who say all students and staff should be required to wear masks and 14% who say this requirement should only be for unvaccinated students and staff.

  • Most Parents Say They Don’t Have Enough Information About COVID-19 Vaccine Safety And Effectiveness For Children Under 5

    Lack of available information may be a factor in parents’ reluctance to get their youngest children vaccinated right away. A majority of parents of children under five say they don’t have enough information about the safety and effectiveness of COVID-19 vaccines for children in this age group (56%). By contrast, most parents of older children feel better informed, with three-fourths of parents of teens and two-thirds of parents of kids ages 5-11 saying they have enough information about vaccine safety and effectiveness for their age group.

  • Majority Of Parents Are Not Confident The COVID-19 Vaccines Are Safe For Children Under Age 5

    Reflecting vaccine intentions among parents of children from different age groups, parents of teenagers express the most confidence in the safety of the vaccines for their kids. Over half of parents say they are confident in the safety of the COVID-19 vaccines for children ages 12-17 (57%), many of whom have already been vaccinated. Fewer parents (45%) are confident in the safety of the vaccines for children ages 5-11, while 32% say they are confident the COVID-19 vaccines are safe for children under the age of 5. Majorities of parents say they are not confident in the safety of the vaccines for children under five (64%) and ages 5-11 (54%).

  • Seven In Ten Women Who Are Pregnant Or Planning To Believe Or Are Unsure About At Least One Piece Of Misinformation Surrounding Pregnancy And COVID-19 Vaccines

    Among those for whom questions about the safety of the vaccines and pregnancy are particularly relevant – women who are pregnant or planning to become pregnant – nearly four in ten (37%) are unsure if pregnant women should not get the vaccines and 44% are unsure if the COVID-19 vaccines cause infertility. Altogether, among women who are pregnant or planning to become pregnant, 60% believe that pregnant women should not get the vaccine or are unsure if this is true, 58% believe or are unsure whether the vaccines have been shown to cause infertility, and 52% believe or are unsure whether it is unsafe for breastfeeding women to get vaccinated.

  • Among Women Under Age 50, About Half Express Confidence That The Vaccines Are Safe For Pregnant People

    Among women between the ages of 18 and 49, seven in ten are confident the vaccines are safe for adults more generally, while just under half (48%) express confidence that they are safe for those who are pregnant or trying to conceive. Unsurprisingly, very few (9%) unvaccinated women under 50 say they are confident the vaccine is safe for people who are pregnant or trying to become pregnant, whereas about two-thirds (64%) of their vaccinated counterparts say they are confident it is safe for that group.

  • Nearly Eight In Ten Believe Or Are Unsure About At Least One Common Falsehood About COVID-19 Or The Vaccine

    Belief or uncertainty about COVID-19 misinformation is widespread, with nearly eight in ten adults saying they have heard at least one of eight different pieces of misinformation and either believe them to be true or are not sure whether they are true or false.

  • One-Third Believe Or Are Unsure About Four Or More False Statements About COVID-19

    One-third of adults (32%) say they have heard at least four false statements about COVID-19 and believe them to be true or are uncertain if they’re true or false. The shares who believe a large number of false statements are highest among unvaccinated adults, Republicans, and those living in rural areas.
