Abstract: A brand new survey discovered that 24% of US adults incorrectly imagine the MMR vaccine causes autism, regardless of CDC proof on the contrary.
This false impression contributes to vaccine hesitancy and rising measles circumstances. The survey highlights the necessity for higher public schooling on vaccine security.
Key Details:
- 24% of US adults incorrectly imagine the MMR vaccine causes autism.
- Measles circumstances within the US have risen considerably, with 146 circumstances in 2024.
- The CDC confirms no hyperlink between the MMR vaccine and autism.

As measles circumstances rise throughout the USA and vaccination charges for the MMR (measles, mumps, rubella) vaccine proceed to fall, a brand new survey finds {that a} quarter of US adults have no idea that claims that the MMR vaccine causes autism are false.
The Facilities for Illness Management and Prevention (CDC) has mentioned there isn’t any proof linking the measles vaccine and getting autism. However 24% of US adults don’t settle for that – they are saying that assertion is considerably or very inaccurate – and one other 3% usually are not positive, in line with the survey by the Annenberg Public Coverage Heart (APPC) of the College of Pennsylvania.
About three-quarters of these surveyed say that assertion is considerably or very correct.
The findings are in step with these in an APPC survey administered by NORC in October 2018, previous to the Covid-19 pandemic. The 2 surveys point out {that a} sizable and constant variety of Individuals both imagine the false connection or have no idea what’s right. The false hyperlink was asserted by Andrew Wakefield in a 1998 Lancet paper that was subsequently retracted.
“The persistent false perception that the MMR vaccine causes autism continues to be problematic, particularly in gentle of the latest enhance in measles circumstances,” mentioned Kathleen Corridor Jamieson, director of the Annenberg Public Coverage Heart.
“Our research on vaccination constantly present that the idea that the MMR vaccine causes autism is related not merely with reluctance to take the measles vaccine however with vaccine hesitancy basically.”
The brand new survey findings are additionally in step with APPC surveys in 2021-2023 which didn’t point out the CDC's steering.
In these surveys, 9% to 12% thought it was most likely or undoubtedly true that vaccines given to youngsters for illnesses like measles, mumps, and rubella trigger autism, whereas 17% to 18% weren’t positive whether or not that’s true or false.
Within the newest survey, performed from April 18-24, 2024, the Annenberg Public Coverage Heart questioned over 1,500 empaneled US adults about their information of how one can contract measles, its signs, and whether or not medical professionals suggest that pregnant folks take the measles vaccine in the event that they haven’t already performed so.
the rise in measles circumstances
The CDC experiences that measles exercise is rising globally in addition to in the USA.
In 2024, as of Could 30 there have been 146 US measles circumstances in 21 jurisdictions, together with 11 outbreaks of three or extra associated circumstances. From January 1, 2020, by means of March 28, 2024, the CDC was notified of 338 confirmed circumstances, of which almost a 3rd (97, or 29%) occurred simply through the first quarter of 2024, which represents a 17-fold enhance over the imply variety of circumstances reported within the first quarters of 2020-2023.
The median affected person age was 3 years outdated. The overwhelming majority of circumstances occurred in sufferers who have been both unvaccinated or whose vaccination standing was unknown.
The share of kindergartners with MMR vaccine protection in opposition to measles dropped in the USA through the pandemic, in line with the CDC. “Measles Outbreaks Develop Amid Declining Vaccination Charges,” famous a JAMA Community headline in November 2023.
Learn about Measles
How Measles Unfold
A majority of survey respondents know the way measles can and can’t be unfold. Almost 6 in 10 accurately say that measles will be unfold by means of coughing and sneezing (59%) and by touching a contaminated floor adopted by touching one's nostril, mouth, or eyes (59%).
Measles can’t be unfold by means of unprotected sexual contact with an contaminated particular person, however over a fifth of these surveyed (22%) suppose it is a option to catch the virus.
Measles Incubation Interval
Only a few of these surveyed know the way lengthy an individual contaminated with measles can unfold the virus earlier than growing the signature measles rash. Simply over 1 in 10 (12%) accurately estimate that an individual can unfold the an infection for 4 days earlier than growing a rash, whereas 12% estimate that the interval is one week. The vast majority of panelists (55%) report not being positive.
Issues of Measles in Pregnant Individuals
The survey requested respondents to pick out whether or not a sequence of potential issues have been related to having measles whereas pregnant. Lower than 4 in 10 folks accurately (in blue under) recognized two issues related to contracting measles whereas pregnant – delivering a low-birth-weight child (38%) and early supply (37%).
A reasonably small variety of folks incorrectly (in yellow under) point out that diabetes (7%), blurred imaginative and prescient (11%), and demise (12%) usually tend to happen in case you have measles whereas pregnant. They don’t seem to be.
Measles vaccination (MMR) whereas pregnant
Most individuals (57%) usually are not positive whether or not pregnant people ought to get vaccinated in opposition to measles in the event that they haven’t already been vaccinated in opposition to it. Nearly one-third (32%) incorrectly suppose that medical professionals suggest that pregnant folks take the vaccine.
Solely 12% know that medical professionals don’t suggest this vaccine for pregnant people. It is because the measles vaccine makes use of a reside, weakened (ie, attenuated) type of the virus.
The CDC notes: “Though MMR is a protected and efficient vaccine, there’s a theoretical threat to the newborn. It is because it’s a reside vaccine, that means it comprises a weakened model of the residing virus.”
The CDC recommends the MMR vaccine be given a month or extra earlier than somebody turns into pregnant, if that particular person was not vaccinated in opposition to measles, mumps, and rubella as a toddler.
APPC's ASAPH survey
The survey knowledge come from the 19th wave of a nationally consultant panel of 1,522 US adults, first empaneled in April 2021, performed for the Annenberg Public Coverage Heart by SSRS, an impartial market analysis firm.
This wave of the Annenberg Science and Public Well being Information (ASAPH) survey was fielded April 18-24, 2024, and has a margin of sampling error (MOE) of ± 3.5 share factors on the 95% confidence stage.
All figures are rounded to the closest complete quantity and should not add to 100%. Mixed subcategories could not add to totals within the topline and textual content resulting from rounding.
The coverage heart has been monitoring the American public's information, beliefs, and behaviors concerning vaccination, Covid-19, flu, maternal well being, local weather change, and different consequential well being points by means of this survey panel for over three years.
Along with Jamieson, the APPC workforce behind this survey consists of Shawn Patterson, who analyzed the information; Patrick E. Jamieson, director of the Annenberg Well being and Threat Communication Institute, who developed the questions; and Ken Winneg, managing director of survey analysis, who supervised the fielding of the survey.
The 2018 survey knowledge comes from the primary wave of the Annenberg Public Coverage Heart's Resistance to Vaccines Longitudinal Survey (RVLS), a panel of three,005 US adults, performed by NORC, an impartial analysis firm.
This wave was fielded between September 21, 2018, and October 6, 2018, and has a margin of sampling error of ± 2.6 share factors on the 95% confidence stage.
