Publisher’s rating: Falsch. Das Video ist weder aktuell noch hat es etwas mit pro-palästinensischen Protesten zu tun. Das bestätigte die Polizei Mannheim. Der Clip kursiert mindestens seit Ende Mai 2023. Die Aufnahme wurde damals im Zusammenhang mit der Stichwahl um das türkische Präsidentenamt verbreitet.

Em post no X, Osmar Terra contesta a eficácia das vacinas contra a covid-19 ao fazer uso de números de mortes na pandemia em Taiwan, Austrália e Japão.

Publisher’s rating: Enganoso

The review examines a post by federal deputy Osmar Terra that used COVID-19 death figures from Japan, Taiwan and Australia to argue against vaccine effectiveness. It concludes that those figures do not establish that vaccination was ineffective. The post contained data inconsistencies and compared overall vaccination levels with deaths across different time intervals; those totals did not reveal whether the people who died were vaccinated or unvaccinated. [S1: “Além de haver inconsistências nos dados apresentados pelo parlamentar, a comparação direta entre número de mortes e percentual geral de vacinados em intervalos diferentes de tempo não indica a eficácia, ou não, das vacinas”] The review describes a more relevant comparison, identified by epidemiologist Sérgio de Andrade Nishioka: death rates among vaccinated and unvaccinated people. It cites an Australian study that used this approach. Among older adults, vaccination reduced the risk of death by 93% compared with unvaccinated older adults. In the general population, unvaccinated people accounted for 4.6% of COVID-19 cases but 22.8% of deaths. [S1: “Um estudo sobre a pandemia na Austrália, um dos países citados por Terra, utilizou o método indicado por Nishioka e mostrou que a vacinação de idosos reduziu o risco de morte em 93% em comparação com idosos não vacinados. Entre a população geral, aqueles que não foram vacinados representaram apenas 4,6% dos casos de covid-19, mas 22,8% das mortes ocorreram entre pessoas que não receberam dose alguma.”] It also cites a study published in The Lancet in August 2022, which reported that vaccination reduced COVID-19 deaths by 67% in Japan and cases by 33%. These findings provide evidence that the post’s aggregate comparisons could not supply: they concern outcomes assessed in relation to vaccination, rather than treating total deaths and the overall share vaccinated as proof of vaccine failure. [S1: “Já um estudo publicado no The Lancet em agosto de 2022 mostrou que a vacinação reduziu em 67% as mortes por Covid no Japão e em 33% o número de casos.”]

Het mRNA-luchtvaccin van Bill Gates is goedgekeurd voor gebruik tegen niet-instemmende mensen.

Publisher’s rating: Nee, er is geen goedgekeurd mRNA-vaccin dat door de lucht wordt verspreid zodat mensen het inademen. De bewering is afkomstig van een notoire nepnieuwssite. Een artikel op die site verwijst naar een studie van Yale over een nieuwe methode om mRNA via de neus in de longen te brengen, maar legt die studie verkeerd uit. Bill Gates heeft er overigens niets mee te maken.

lemon and salt help heal tongue ulcers

Publisher’s rating: Mostly False

Related reporting examined a warm-water remedy containing turmeric, honey, lemon juice and rock salt that was promoted as a way to resolve mouth ulcers. The report’s assessment therefore bears directly on the claim that lemon and salt help heal tongue ulcers, although the excerpt discusses mouth ulcers generally rather than ulcers specifically located on the tongue. It states that the mixture’s ingredients are “not supported by scientific research” as a cure for mouth ulcers. The evidence described is ingredient-specific: the report says clinical evidence is insufficient to support turmeric’s direct role in healing oral ulcers, and that lemon juice “might not have an impact on their healing process.” It also warns that lemon juice’s acidity can irritate ulcerated tissue and potentially delay healing. Salt-water rinses may help keep the mouth clean and reduce swelling, but the report does not present rock salt as a proven ulcer-healing treatment; excessive use may cause discomfort. It distinguishes these possible supportive effects from curing ulcers, noting that anecdotal reports of short-term relief do not establish that the mixture heals them.

Em um vídeo, médico afirma, citando um estudo, que vacinas vão causar, no futuro, “epidemia de doença cardiovascular, epidemia de doença autoimune, epidemia de câncer, e isso se daqui a uma ou duas gerações a gente não tiver uma epidemia de infertilidade junto, entre outras coisas” ao mudar o código genético das pessoas.

Publisher’s rating: Falso

The video claim is that a doctor cited a study as evidence that Pfizer’s COVID-19 vaccine changes people’s genetic code and will lead to epidemics of autoimmune disease, cancer and infertility. The review identifies the cited research as a Swedish study of the Pfizer vaccine, but says it did not establish that the vaccine changes human genetic code or predict future disease epidemics. The study examined liver-cell lines in laboratory conditions, not people or other living subjects, and its authors identified that limitation. The study’s reported findings were narrower: the vaccine entered liver cells in culture six hours after administration, and DNA converted from messenger RNA appeared in host cells. Crucially, the review says the researchers did not know whether that converted DNA had integrated into the cells’ DNA—whether it had compromised the genome. The review also reports that the study made no predictions about any disease. These findings therefore do not support the video’s claims about genetic alteration in people or future epidemics. The review says specialists consulted by Comprova pointed to other studies indicating that the vaccine does not modify DNA. It also reports that Comprova sought a response from the doctor’s team but received no answer before publication. The material provided does not name the doctor or identify the video’s original platform.
