Mensen zonder symptomen vormen geen enkel besmettingsgevaar.
Publisher’s rating: Het bericht klopt niet. De onderzoekers waar men zich op baseert hebben iets totaal anders onderzocht. Zij deden geen onderzoek naar of asymptomatische mensen anderen kunnen besmetten, maar hebben slechts gekeken naar de CT-waardes in positieve PCR-tests. Bovendien kunnen mensen al zo’n twee dagen vóór het ontwikkelen van symptomen besmettelijk zijn.

82% of women vaccinated against Covid-19 in the first third of pregnancy suffer miscarriages
Publisher’s rating: False. At no point did the researchers in the study link the rate of miscarriage to the stage of pregnancy at which a woman was vaccinated

Cardiologen van het UZ Leuven (Gasthuisberg) maken melding van opvallende stijging van bloeddrukproblemen, zona en allerhande andere infecties. Ze linken dit aan de coronavaccins.
Publisher’s rating: De dienst cardiologie van het UZ Leuven ontkent zulke vaststellingen te hebben gedaan in hun praktijk. Er is geen bewezen link tussen de coronavaccins enerzijds en bloeddrukproblemen, ontstekingen of zona anderzijds.
The claim originated in a Facebook post alleging that cardiologists at UZ Leuven’s Gasthuisberg had noticed a striking rise in blood-pressure problems, shingles and other infections, and connected those observations to coronavirus vaccination. The review checked the allegation with Thomas Vanassche, a cardiologist at UZ Leuven. He said that he and his colleagues had not made the claimed observations in their practice: “Niemand van ons heeft zoiets ondervonden.” The review distinguishes a sustained rise in blood pressure from a temporary fluctuation. Vanassche said blood pressure naturally varies during the day and that stress, tension or pain can temporarily raise it. He said a temporary increase after a vaccination could be attributable to the circumstances of the moment, rather than the injection itself; he reported no observed link between vaccination and a systematic increase in blood pressure at UZ Leuven. On shingles, the review reports that the hospital had not observed more cases and that Vanassche knew of no established link to coronavirus vaccines. The Facebook post did not specify which other inflammations it meant. Vanassche mentioned rare cases of heart-muscle inflammation after vaccination reported in the United States and Israel, but said he was unaware of significant cases in Belgium at the time. Thus, the post’s broad claim of increased infections and vaccine links was not supported by the observations described in the review.
Geimpfte scheiden Spike-Proteine aus, die Ungeimpften schaden.
Publisher’s rating: Falsch. Geimpfte produzieren nach der Corona-Impfung zwar geringe Mengen des Spike-Proteins, diese werden aber im Körper abgebaut und können nicht ausgeschieden werden. Spike-Proteine können sich alleine nicht vermehren und sich auch nicht gefährlich für Ungeimpfte.
Die Delta-Variante ist „mindestens 10-fach weniger gefährlich” als frühere Varianten.
Publisher’s rating: Die Case Fatality Rate (CFR) gibt an, wie viele der Corona-Infizierten sterben. Die Rate ist tatsächlich bei der Delta-Variante in Großbritannien derzeit niedriger als jene von Alpha oder Beta. Nur auf Basis dessen lässt sich aber nicht sagen, dass die Delta-Variante weniger gefährlich ist. In Bezug auf die CFR müssen mehrere Faktoren wie etwa der Impffortschritt miteinbezogen werden. Es ist derzeit nicht eindeutig, ob die Variante zu mehr Hospitalisierungen führt oder eine höhere Sterblichkeit hat. Studien zufolge ist sie aber ansteckender.
網傳「英國航空公司飛機駕駛員過去七天就死了三位；航空公司警告打過疫苗的人最好不要坐飛機，因為有血栓的危險；美國CDC被控誇大冠状病毒死亡数字」的訊息。

Het Australische leger gaat langs de deuren, op zoek naar antivaxxers.
Publisher’s rating: Er is geen enkel bewijs dat Australische militairen van deur tot deur op zoek zijn naar antivaxxers. Het lijkt hier te gaan om een broodjeaapverhaal. Het Australische leger doet in de staat Victoria wel huisbezoeken bij mensen die in contact zijn geweest met iemand met COVID-19 of die terugkomen van een reis. Maar hierbij wordt dus niet specifiek gezocht naar mensen die zich niet zouden willen laten vaccineren.
Foto toont protesten in Franrkijk in juli 2021 tegen de verplichte vaccinatie van verplegend personeel en de "indirecte vaccinatieplicht" in Frankrijk.
Publisher’s rating: De foto is echt, maar dateert van 24 november 2018. Hij werd genomen tijdens een protestactie van de Gele Hesjes in Parijs. Er is nog steeds een pandemie gaande en PCR-tests zijn wel degelijk betrouwbaar en geschikt om een besmetting met het SARS-CoV-2-virus te detecteren.
The post paired a photograph of a crowd near Paris’s Arc de Triomphe with a claim that it showed protests in France on 14 July 2021 against COVID measures and direct or indirect vaccination requirements. The investigation identifies the image as an older photograph: it was taken in Paris during a Yellow Vests protest on 24 November 2018, rather than at the July 2021 demonstrations. The review says the photograph was made by French photojournalist Olivier Coret and appeared in a Daily Mail article on the day it was taken. The review gives several visual reasons the image does not fit July 2021: most people are wearing winter clothing and yellow fluorescent vests, and the trees appear bare. It also reports that the photograph’s date is clearly visible. These clues support the review’s identification of the image as a 2018 scene, not as a photograph of the later protests. The distinction matters because protests did take place in France on 14 July 2021, but the review describes their subject as opposition to the planned “pass sanitaire.” It says that measure was due to apply from 21 July to people over 12 for most cultural and leisure activities, while vaccination was being made compulsory for healthcare personnel. Those events provide real contemporary context, but they do not establish that this particular photograph came from them.
Les présidents de trois de ces cinq pays (Corée du Nord, Haïti, Erythrée, Burundi et Tanzanie) qui n'ont encore vacciné personne sont décédés dans les six derniers mois, dont le président haïtien assassiné tout récemment. Quel hasard !
Publisher’s rating: Il est vrai que les cinq pays évoqués par l’utilisateur dans son post en date du 8 juillet 2021 n’avaient pas encore lancé leur campagne de vaccination contre le Covid-19. Il est aussi vrai que trois présidents de ces pays (Haïti, Burundi et Tanzanie) sont morts en exercice. Cependant, en ce qui concerne le Burundi, il ne s’agit pas d’un fait récent puisque celui-ci remonte à juin 2020. De plus, la formulation de l’utilisateur laisse entendre que ces décès pourraient avoir un lien avec la politique vaccinale des pays concernés – une thèse qui n’est soutenue par aucun élément.

Der in einer Studie festgestellte Anteil an Fehlgeburten unter Schwangeren mRNA-Geimpften ist «erschreckend».
Publisher’s rating: Hier fehlt nötiger Kontext. Tatsächlich hatten der Studie zufolge 12,6 Prozent der Frauen eine Fehlgeburt. Dieser Wert liegt allerdings im Durchschnitt. Die vorläufigen Ergebnisse der Studie deuten nicht auf Sicherheitsbedenken hin. Das bestätigen Angaben mehrerer Gesundheitsinstitutionen.
The claim describes the 12.6% miscarriage figure in a study of pregnant people who received mRNA COVID-19 vaccines as alarming. The review says that figure refers to 104 miscarriages among 827 participants with a completed pregnancy—not to all 3,958 people enrolled. It also reports 115 pregnancy losses in total, alongside 712 live births and other outcomes. The distinction matters because the headline figure uses the completed-pregnancy group as its denominator. To assess whether the figure was unusually high, the review compared it with miscarriage estimates from several sources. It reports estimates of 15.3% among recognized pregnancies from The Lancet, 10–15% from the US March of Dimes, and 10–20% from Planned Parenthood. Those comparisons place the study’s figure within the cited ranges, rather than showing an unusually high rate. The review also says the NEJM study described the rate of negative pregnancy outcomes as appearing similar to pre-pandemic findings, while cautioning that the groups were not fully comparable. The evidence does not establish that the study ruled out every possible vaccine-related risk. The review notes that most participants received their first dose later in pregnancy, after the period of greatest miscarriage risk, and that very early miscarriages might not have been detected. It reports the study’s preliminary conclusion that no safety concerns had emerged, while also noting that further research, including on earlier pregnancy stages, was needed. Thus, the figure alone does not support describing the result as alarming, but the review records important limits on what could be concluded.
