Still False analyzes of their effectiveness are circulating. Elon Musk recently hit this notch. Based on more than 100 English-language newspaper clippings, the... decreasing effectiveness of the corona vaccinations can be proven. End of September Elon Musk, head of X (formerly Twitter) and Tesla, also shares his views A video that has been circulating online for a long time with more than 150 million followers with a quick succession of headings and quotes. The clip awakens the impression that the effectiveness of the vaccines against the Covid pathogen Sars CoV-2 has continued to decrease over time. ## Evaluation Misleading in several ways. First: It is not a chronological order Newspaper articles, the data is mixed up. Second: There will be studies listed, which cannot be meaningfully compared with one another because of the lack of data is often completely different. ## Facts The sequence of the slideshow gives the impression that over time the... Corona vaccines lost safety and effectiveness: At the beginning of the video There is talk of 100 percent effectiveness (in the video from 0:04 min.), later from 85 percent (from 0:25 min.), then from 50 (from 0:50 min.) and 39 Percent (from 0:55 min.). At the end the question is asked (from 1:31 min.) how ineffective the vaccines are real. For the supposed drama Edvard Grieg's “In the Hall of the Mountain King” with musical accompaniment. Headings not chronological In fact, the 100+ article titles or citations were predominately published between September 2020 and October 2021. That was an important one Phase in vaccine development: The first vaccines were released in December 2020 for the first time for regular use in humans outside of studies approved. The order of publication is actually completely different than in Musk's video: The articles reporting the lowest effectiveness were created very early in vaccine development - in some cases even in the time before the first vaccinations at all. One of the excerpts is particularly misleading: the headline “Japan stops vaccines after deaths of 4 children” (from 1:18 min.) is from 2011 and does not refer to the coronavirus at all, but to vaccinations against it Pneumonias. The news in the compilation is fundamentally not straightforward comparable - especially not if you only have quotes or headlines juxtaposed. Different vaccines The articles listed cover studies on different vaccines - for example from Biontech/Pfizer, Moderna or AstraZeneca. Examination results of one vaccine cannot be in a meaningful way with those of another be provided. For example, an article in the magazine “Pharmaceutical Technology” with the title “Bharat Biotech\'s Covid-19 vaccine shows interim efficacy of 81%” (from 0:29 min.). This is about effectiveness the Biontech vaccination also against new corona variants. In contrast, the “India Times” deals with this in its article “Johnson & Johnson Vaccine Is 68% Effective on COVID-19 Strains, Seeks FDA Approval” (from 0:39 Min.) the vaccine from Johnson & Johnson, which despite its lower effectiveness was nevertheless approved. Both remedies differ in terms of administration (in contrast to the others are initially given Johnson & Johnson as a single dose). also in production. Different Corona variants Over time, the coronavirus has changed and new variants and Mutations have appeared. A vaccine for one variant has been developed and is highly effective against these, its protection must may not necessarily be as pronounced in another. A CNN report from March 2021 titled “Pfizer/BioNTech says its Covid-19 vaccine is 100% effective and well tolerated in adolescents” (from 0:05 Min.) According to the vaccine manufacturer, the vaccine manufacturer had very good results in one clinical study. In an article in the Daily Mail just five months later with the headline «Pfizer\'s Covid vaccine is only 42% effective against Indian \'Delta\' variant while Moderna\'s jab is 76% effective, Mayo Clinic suggests" (from 0:53 Min) will then have a much lower effectiveness against the Delta variant specified. The difference between the articles: The CNN report covers a study on Biontech's effectiveness against the original type of coronavirus, the "Daily Mail" on the other hand, the effectiveness of the same remedy against the later is considered new Delta variant that has emerged. Different study design The studies mentioned in the different articles differ among other things, in the implementation of the investigation and its objectives. This is what the first heading in the video montage describes (“AstraZeneca COVID-19 Vaccine 100% Effective In Preventing Deaths, Hospitalization: US Study») press release belonging to Vaccine manufacturer the results of a phase III study by AstraZeneca Vaccine - the last stage of a clinical trial before that drug comes onto the market. The message “CDC: Pfizer, Moderna vaccines are 90% effective in real-world conditions” (from 0:21 min.), on the other hand, refers to a real-life study by the US health authority CDC, in which the participants are selected differently than in clinical studies. This can lead to significant differences in the lead to results. More precisely: In AstraZeneca's phase III study, the results were of three studies from Great Britain, Brazil and South Africa with a total of 17 177 participants combined. Participants who are at least 18 years old All three studies were healthy or had stable chronic conditions diseases. They also had an increased risk of coming into contact with Sars-CoV-2 to come. After vaccination, they were tested several times a year for viral load and check vaccination coverage. The CDC real-life study involved 4,000 employees and... Employees in the health system or in system-maintaining jobs tested weekly to determine the effect of the Pfizer and Moderna vaccinations watch - but not that of AstraZeneca. How effective the Covid vaccines really are In fact, vaccinated people are often still contagious, but they carry a significant amount of infection lower viral load and therefore reduce the likelihood of one serious illness of others. The vaccination does not necessarily protect against one Infection of the vaccinated person, but rather a severe course Hospital stays and often before deaths, like the American Johns Hopkins University writes. According to the World Health Organization (WHO), there were worldwide at the end of October 2023 more than 771 million confirmed Covid cases and almost seven million deaths. More than 13.5 billion vaccine doses have been administered worldwide. The German Press Agency has already done so several times in the past False claims about the effectiveness of vaccines refuted: for example here, here, here, here, here and here. (As of October 31, 2023) ## Correction In the penultimate paragraph it was corrected that worldwide more than 13.5 billion Vaccine doses were administered, not 13.5 million. ## Links Elon Musk Slideshow (post archived, clip archived) Fox News report (archived) NPR story on vaccine effectiveness (archived) CNN report on the corona vaccination in September 2020 (archived) “Daily Mail” article from August 2021 (archived) “Consumer Affairs” on the Pfizer vaccination in Israel in July 2021 (archived) NBC on pneumonia vaccinations in Japan in March 2011 (archived) Astrazeneca Phase III study February 2021 (archived) Astrazeneca Phase III study March 2021 (archived) “Axios” about CDC study (archived) WHO dashboard on Covid cases and vaccinations (archived on October 30, 2023) EMA to approve the first corona vaccination (archived) FDA approves the first corona vaccination in the USA (archived) Johns Hopkins University on corona vaccinations (archived) “India Times” on Johnson & Johnson (archived) “New York Times” on vaccine differences (archived) “Pharmaceutical Technology” to Biontech (archived) CNN report on Pfizer/BioNTech vaccine (archived) dpa fact checks on the effectiveness of corona vaccinations: here, here, here, here, here and here ### About dpa fact checks This fact check was carried out as part of the Facebook/Meta independent program Fact check created.
