Food and Drug Administration (FDA) requires researchers to submit a clinical trial protocol to describe the elements of the study, its goals, and how data is to be collected and reported. Image sent by Snopes readersīefore a clinical trial may begin, the U.S.

(We have linked to an archive of those documents here.) Some social media users republished the authentic title page of the clinical trial protocol but misrepresented its contents:Īuthentic title page of the Pfizer mRNA vaccine clinical trial protocol highlighted by social media. These documents do indeed describe clinical trial protocol for phases 1, 2 and 3, but as the research and healthcare center Nebraska Medicine reported in April 2021, such claims that vaccines can “shed” the virus are misrepresentations of actual data published by Pfizer. (A phenomenon dramatically dubbed “humanicide.”)

Some people who pushed back against vaccines referred to authentic documents published by Pfizer that were said to report the mRNA vaccine produced by the biopharmaceutical company can environmentally expose unvaccinated people to spike proteins contained within the vaccine, via inhalation or skin contact. Understanding the So-called 'Pfizer Documents' In some cases, this exposure can trigger disease in a recently vaccinated person. These vaccines release a small portion of the virus in the body to stimulate a live response. Vaccines that can shed are those known as live attenuated vaccines, which include those that protect against mumps and rubella. Neither of the above contain SARS-CoV-2, the virus that causes COVID-19, and there is no evidence to suggest that the spike protein sheds. “When an immune response begins, antibodies are produced, creating the same response that happens in a natural infection.”īy comparison, the one-shot Johnson & Johnson is a more traditional, viral vector vaccine that contains a modified piece of a common virus known as an adenovirus - which is not necessarily a coronavirus - that exposes the body’s immune system without the ability to reproduce. Our immune system then recognizes that it does not belong there and responds to get rid of it,” wrote the Centers for Disease Control and Prevention (CDC). "After making the protein piece, cells display it on their surface. The mRNA vaccines do not contain a live virus but instead teach the body to make a piece of a “spike protein” that is found on SARS-CoV-2 and causes COVID-19 infection. contain one.Īs of this writing, two types of vaccines are currently available under emergency use authorization in the U.S.: mRNA vaccines like Comirnaty (formerly Pfizer-BioNTech) and Moderna. While it is true that some vaccines containing a weakened version of a virus can cause shedding, none of the vaccines authorized for use in the U.S. Vaccine shedding, on the other hand, refers to the release of vaccine components outside of the body.
Viral shedding occurs when an infected person sheds virus particles from their nose and mouth, which is an entirely real phenomenon and the reason masks have been effective in preventing the spread of COVID-19. COVID-19 Vaccines Currently Available in US 27 blog post claimed that “Pfizer Confirms COVID-Vaccinated People Can ‘Shed’ Spike Proteins And Harm The Unvaccinated,” noted Poynter. Such allegations resurfaced in the fall when a viral Oct. A closer look at the various iterations of the claim revealed that the controversial and conspiracy-touting medical group, America’s Frontline Doctors, issued a “ press release” in April that made unproven claims about COVID-19 vaccine shedding, PolitiFact reported at the time. Since at least spring 2021, claims spread that vaccinated people can “shed” elements contained within the COVID-19 vaccines that may harm unvaccinated individuals. However, none of the COVID-19 vaccines authorized for use in the U.S. It is true vaccines containing a weakened version of a virus, known as live attenuated vaccines, can sometimes cause shedding. Snopes readers asked our team to investigate whether this was true. One such claim was that individuals vaccinated against COVID-19 can shed viral components that are capable of infecting and harming those around them.
