Missing from the right

Only 2 of the 14 outlets with a published leaning rating that ran this story are rated right.

A reader who follows the right would not have seen this. We report the absence rather than explain it: outlets choose what to cover for many reasons, and we have no evidence about which one applies here.

President Donald Trump signed an executive order on 10 August 2026 directing the separation of the measles, mumps and rubella (MMR) vaccine into three individual shots. The order, announced at the White House, also reduces the number of recommended childhood vaccines from 18 to 11. A White House fact sheet, first reported by The Daily Caller, states the order will advise states with school vaccine mandates to consider updating their laws to reflect the new recommendations.

The order proposes dividing childhood vaccines into three categories. All children are recommended to receive vaccines for measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Hib, pneumococcal disease, HPV and varicella, according to a draft obtained by CNN. Vaccines for hepatitis A, hepatitis B, meningococcal B, meningococcal ACWY and dengue are now recommended only for high-risk populations. The order also introduces shared decision-making for vaccines such as rotavirus, meningococcal disease, influenza and Covid-19, meaning parents and doctors will discuss whether to administer them.

Trump has long advocated for spacing out childhood vaccines, citing concerns about a link between vaccines and autism. The order follows a December 2025 directive to the Department of Health and Human Services (HHS) to review how peer nations approach vaccine recommendations. In January 2026, HHS reduced the number of recommended vaccines, a move later blocked in court. Trump has publicly pressed HHS Secretary Robert F. Kennedy Jr. to identify the cause of autism, as reported by the Associated Press.

Public health experts have warned that separating the MMR vaccine and spacing out shots could increase the risk of children contracting vaccine-preventable diseases before completing the series. The Associated Press reported that separate measles, mumps and rubella vaccines for children are not currently available in the U.S. The order comes as the U.S. faces a measles outbreak, which experts say could lead to the loss of the country’s measles elimination status.

What the reports disagree on

The reports differ on whether Trump specified which vaccines should be spaced into five separate visits for one-year-olds. The Associated Press reported that it was unclear whether Trump was referring to all vaccines or specific ones. CNN did not mention this detail in its full report.

What the coverage left out

None of the digests from the right-rated report mentioned the public health warnings about increased disease risk from spacing out vaccines. The centre-rated digests from CBS News, Washington Top News and Reuters did not specify which vaccines would be affected by the order or the division into three categories. The left-rated digests from The Independent, CNN and Axios did not detail the reduction from 18 to 11 vaccines or the shared decision-making process for certain vaccines.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

9 rated outlets

  • Left-rated outlets reported that President Donald Trump signed an executive order directing the separation of the measles, mumps and rubella (MMR) vaccine into three individual shots. All 12 digests and the Associated Press report confirmed the order calls for revised childhood vaccine recommendations, including spacing out immunisations into separate visits.
  • The Associated Press report and nine digests noted the order follows Trump’s long-standing belief that vaccines should be administered separately. The AP and CNBC digests explicitly stated the order falsely links vaccines to autism. The AP report quoted Trump asking Health Secretary Robert F. Kennedy Jr. about progress on autism research during a Cabinet meeting.
  • Public health concerns were highlighted in the AP report and three digests, which noted experts warn spacing out vaccines increases the risk of children contracting preventable diseases. The AP report added that separate MMR vaccines are not currently available in the U.S. and that states, not the federal government, set school vaccine requirements.
  • Omissions in the digests included the White House fact sheet’s details on advising states to update vaccine mandates and the court block on a previous HHS move to reduce recommended vaccines. The AP report alone carried Trump’s remark about one-year-olds receiving shots in five separate visits.

Centre

3 rated outlets

  • The centre-rated reports focused on the administrative and political aspects of the order. CNN’s full report led on the reduction of recommended vaccines from 18 to 11 and the division of the childhood vaccine schedule into three categories. It also noted that the order advises separating the MMR vaccine into three individual shots, against broad scientific consensus.
  • CBS News and Washington Top News digests mentioned the signing of the executive order but provided no additional details. Bloomberg’s digest reported that the order would recommend breaking up the combined MMR vaccine into three separate shots. Reuters’ digest described the order as calling for “more vaccine flexibility and research.”
  • CNN’s full report included Trump’s statement from the Oval Office: “We’re reducing them. It’s not only that you’re doing fewer vaccines, or jabs, as they say, but you’re doing them in a series of visits to the doctor.” It also noted that the order hews closely to a January 2026 HHS effort to reduce the number of recommended vaccines, which was later blocked in court.

  • The right-rated digest from the Washington Examiner led on the reduction of childhood vaccines from 18 to 11 and the separation of the MMR shot. It did not mention public health concerns or the scientific consensus against the order’s recommendations.

Questions about this coverage

How did the left and right cover Trump orders split of MMR vaccine into three separate shots?
Of the 14 outlets on this story carrying a published leaning rating, 64% are rated left, 22% are rated centre, 14% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it. The sections above set out what each side emphasised, in its own terms.
Is Trump orders split of MMR vaccine into three separate shots left or right?
Neither side dominates it. Of the 14 rated outlets on this story, 64% are rated left, 22% are rated centre, 14% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Trump orders split of MMR vaccine into three separate shots biased?
Trump orders split of MMR vaccine into three separate shots is one event reported by 14 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting Trump orders split of MMR vaccine into three separate shots?
When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered Trump orders split of MMR vaccine into three separate shots?
14 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
What does Trump’s executive order on vaccines do?
The order splits the combined measles, mumps and rubella (MMR) vaccine into three separate shots and reduces the number of recommended childhood vaccines from 18 to 11. It advises states with school vaccine mandates to update their laws, though states retain authority over vaccination requirements. The order also introduces shared decision-making for certain vaccines.
Why are public health experts concerned about the order?
Public health experts warn that spacing out vaccines increases the risk of children contracting preventable diseases before completing the series. The Associated Press reported that separate MMR vaccines are not currently available in the U.S., and the order comes amid a measles outbreak that could lead to the loss of the country’s measles elimination status.
Which vaccines are still recommended for all children under the order?
According to a draft obtained by CNN, the order recommends all children receive vaccines for measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Hib, pneumococcal disease, HPV and varicella. Vaccines for hepatitis A, hepatitis B, meningococcal B, meningococcal ACWY and dengue are now recommended only for high-risk populations.
Can the federal government mandate childhood vaccines?
No. The Associated Press reported that states, not the federal government, have the authority to require vaccinations for schoolchildren. The executive order advises states with school vaccine mandates to consider updating their laws to reflect the administration’s recommendations.
