A roundup of some of the most popular but completely untrue stories and visuals of the week.

None of these are legit, even though they were shared widely on social media. The Associated Press checked them out.

Here are the facts:

Claim

After a legal challenge from Robert F. Kennedy Jr. and a group of scientists, the U.S. Supreme Court has ruled COVID-19 vaccines are unsafe and “canceled universal vaccination.”

The facts

The Supreme Court has not issued any rulings regarding the safety of coronavirus vaccines and Kennedy, a lawyer who has advocated against vaccines, called articles sharing the claim “misinformation.”

Dozens of posts making the false claim link to blogs that regularly publish hoaxes and misinformation.

The claim has been circulating for months and recently reemerged as new vaccine requirements issued by the federal government take effect.

The articles and posts include a supposed quote from Kennedy. But Kennedy told The Associated Press that the articles are false, as is the quote. “The quote is fabricated,” Kennedy said. “Clearly somebody made it up and is promoting it because the same quote keeps coming back no matter how many times I deny it.”

Furthermore, there is no legal case that matches the one described in the articles.

“The U.S. Supreme Court has not ruled in a case involving a challenge to a Covid-19 vaccination requirement,” Joanne Rosen, a senior lecturer at the Johns Hopkins Bloomberg School of Public Health, wrote in an email to AP. Rosen has studied the legislative precedent for vaccine mandates.

While ??Kennedy said he has been a part of more than 30 lawsuits on the subject of vaccine safety, those are at different stages of the judicial process and none have appeared before the Supreme Court.

Claim

The New England Journal of Medicine posted a correction earlier this month that backtracked on its earlier statements. The journal now admits the COVID-19 vaccine may not be safe for pregnant women.

The Facts

The medical journal did not “backtrack” or suggest that COVID-19 vaccines could be unsafe for pregnant women, as vaccine critics have falsely claimed on social media.

Posts online misrepresent the journal’s Sept. 8 correction, which addressed an update in Centers for Disease Control and Prevention data, while still arriving at the same conclusion: that the vaccines were not found to be harmful to pregnant people.

The CDC updated an original report on vaccines in pregnant people “to address an issue about how the risk calculation was performed,” according to Jennifer Zeis, director of communications and media relations for NEJM Group.

The initial CDC report, published online in April and in print in June, included only a small portion of people who had been vaccinated early in pregnancy.

An accompanying editorial based on that incomplete information included an estimated risk for miscarriage before 20 weeks of pregnancy and said the risk was within the expected range for the pregnant population as a whole.

NEJM’s correction deleted that wording, along with the risk estimate.

The same day, the journal published a CDC research letter that included additional data and estimated that the risk for miscarriage among individuals vaccinated early in their pregnancies ranged from 14% to 19%, which the authors said was “within the expected risk range” for pregnant people generally.

March of Dimes statistics indicate that 10% to 15% of people who know they are pregnant miscarry, but the nonprofit says as many as half of pregnancies may end in miscarriage.

The exact number isn’t known, because some people lose their pregnancies before they realize they are pregnant.

The CDC data on which the NEJM’s conclusions were based included people who didn’t realize they were pregnant until after they were vaccinated. The CDC on Aug. 11 urged all pregnant people to get vaccinated for COVID-19 to protect themselves and their children.

Leading obstetrician groups also have recommended the vaccines for pregnant individuals, who face an elevated risk of severe illness if infected with the coronavirus.
