Publisher’s rating: Misleading

The review assessed social-media posts claiming that masks cause cancer and can make the body acidic, damage DNA, impair organs and cause other serious illnesses. It says it examined the scientific basis for those claims. The review reports finding no scientific evidence that wearing a mask causes cancer, and no credible scientific evidence that masks cause DNA mutations or organ failure. It distinguishes these claims from established causes of those outcomes, noting that DNA mutations involve many genetic and environmental factors and that organ failure is generally associated with specific medical conditions, infections or chronic disease. On acidity and breathing, the review says masks cannot significantly alter blood pH, which it describes as tightly regulated. It also says carbon dioxide molecules can pass through masks, and reports that infectious-disease specialists found no scientific evidence that cloth and surgical masks cause breathing problems. It qualifies this discussion by saying that wearing an N95 for hours can significantly reduce blood oxygenation; the excerpt does not provide study details or measurements for that statement. The review separately discusses graphene, rather than treating all masks as containing it. It says some masks have used graphene-containing outer layers, and reports that Canada’s health department in April 2021 advised people to stop using certain graphene-containing masks made in China after concerns about inhalation and preliminary indications of possible lung toxicity. It says the risk to humans was still being examined. The review’s overall conclusion is that the cancer and other broad health-harm claims are misleading and unsubstantiated, while acknowledging a potential concern about inhaled graphene and advising that masks be used as appropriate. The excerpt also contains a confusing sentence about whether graphene in masks or vaccines poses a significant risk; it does not supply evidence resolving that wording.

Bill Gates a déclaré que les personnes qui refusent les vaccins à ARNm seront exclues de la société.

Publisher’s rating: Non, aucune preuve n'atteste que Bill Gates ait formulé cette hypothèse. L'expression « tsunami de médicaments à ARNm », qui lui est attribuée à tort, a été utilisée par Melissa J. Moore, la directrice scientifique de la firme pharmaceutique Moderna, lors d'une conférence TED en avril 2022. Elle n'y évoque toutefois à aucun moment l'exclusion sociale d'éventuels patients.

The claim combined two allegations: that Bill Gates announced a “tsunami” of mRNA medicines and that people refusing them would be excluded from society. The dpa review found no evidence that Gates made either statement. It traced the circulating posts to an August 27, 2023 article that attributed the quotation to a supposed post by Gates on X, but reported that searches found no trace of that post on the platform or in Wayback Machine’s recently archived Gates posts. The review identified the quotation’s actual source as Melissa J. Moore, Moderna’s chief scientific officer. In an April 2022 TED talk about mRNA-based therapies, Moore said that clinical research activity could lead to a “tsunami” of mRNA-based treatments. The review reports that, at 11:14 in the talk, she referred to 175 clinical studies underway in the United States and 54 more awaiting approval. That is a forecast about treatments, not a statement by Gates or a proposal to compel treatment. Crucially, the review says Moore did not advocate excluding patients who declined treatment. Thus, the viral account misattributed Moore’s remark to Gates and added a social-exclusion claim the review says was absent from her talk.

Bill Gates heeft gezegd dat mensen die zich verzetten tegen de komende mRNA-tsunami zullen worden uitgesloten van de samenleving.

Publisher’s rating: Nee, de woorden "tsunami van mRNA-medicijnen" werden niet uitgesproken door Bill Gates, maar door een biochemicus uit de farmaceutische industrie, Melissa J. Moore. Ze deed de uitspraak in een TED-talk over de mogelijkheden van mRNA-technologie. Moore sprak daarbij niet over uitsluiting. Een afbeelding van een tweet van Gates hierover blijkt vervalst.

Une compagnie aérienne américaine et des journalistes ont fait fuiter l'information selon laquelle le port du masque sera de retour en octobre 2023 et le confinement en décembre 2023.

Publisher’s rating: Non. Il n'existe aucune preuve indiquant que le gouvernement américain préparerait un tel plan. La TSA a déclaré à la Deutsche Presse-Agentur (dpa) ne pas avoir reçu de telles instructions. Actuellement, l'administration n'impose aucune exigence liée au port du masque.

Es gab im August 2023 eine mysteriöse Serie von Herzinfarkten unter Piloten, wie fünf solcher Fälle zeigen. Auch ab Frühjahr 2021 gab es eine auffällige Häufung von Fällen medizinischer Notfälle unter Piloten.

Publisher’s rating: Nur bei einem der fünf erwähnten Notfälle unter Piloten ist ein Herzinfarkt bekannt. Die Europäische Agentur für Flugsicherheit hat keine Hinweise darauf, dass Untauglichkeiten von Piloten während des Fluges häufiger vorkommen als vor der Pandemie. Bereits im Jahr 2021 dementierte eine US-Pilotenvereinigung, dass es vermehrt zu Todesfällen komme.

The claim drew on five reported cases in August 2023 and alleged a broader increase in pilots’ medical emergencies beginning in spring 2021. The review examined the cases and consulted aviation authorities and pilot organizations; it explains that a simple list of incidents cannot establish a trend without a comparison period or figures for the total number of flights. It also notes that there is no worldwide statistic for pilots’ in-flight medical emergencies, limiting what can be concluded about whether incidents cluster or have become more frequent. The five examples did not all establish what the claim suggested. Four cases were documented, while one could not be verified; one involved a passenger rather than a working pilot. The review found that the medical cause was mentioned in only two cases, so the examples do not substantiate a series of heart attacks. In the Tigerair case, the Taiwanese safety authority reported that the co-pilot lost consciousness after landing in Taipei on August 7, 2023, but no heart condition was reported. The review also found that an IndiGo pilot who collapsed at the Nagpur airport gate died on the way to hospital, with the cause reported as sudden cardiac death. For the broader claim, the European Union Aviation Safety Agency said it had no indication that the share of pilots becoming medically unfit during flights was higher than before the pandemic. The review additionally reports that a US pilot association rejected claims of increased pilot deaths in 2021, explaining that a list commemorating deceased pilots had been misinterpreted. These findings do not establish that no emergencies occurred; they show that the cited cases and evidence do not demonstrate the alleged increase.
