Covid-19 vaccine safetyĪt the time of writing, more than 40 million people in the UK have had at least one dose of a Covid-19 vaccine. PolitiFact said Dr Bridle had not directly produced any evidence to back up his claim. In an automated email response he sent a document with further claims and questions about the vaccines, and said he planned to write a “comprehensive public report”. Julie Bettinger, Associate Professor, University British Columbia told Health Feedback that “nothing about being detrimental is mentioned in the publication”.Īmerican fact checking organisation PolitiFact contacted Dr Bridle directly to ask for more evidence to back up his claim that the Covid-19 vaccine spike proteins are toxins. The study specifically notes that “the clinical relevance of this finding is unknown and should be further explored”. The study found that the spike protein was found in the blood samples of 11 out of 13 participants. Thirdly, the spike protein in Covid-19 vaccines is genetically modified to enhance the immune response and to stop it binding to cell receptors in the same way the SARS-CoV-2 spike protein would.ĭr Byram’s claim that the spike protein leaves the site of the Covid-19 injection and enters the bloodstream, accumulating in other parts of the body, is based on a purportedly leaked Pfizer study carried out by Japanese researchers, which Dr Bridle said is backed up by a small study consisting of 13 participants who had received the Moderna vaccine and provided blood samples. Secondly, the spike protein generated by a Covid-19 vaccine doesn’t assemble into new viral particles, unlike the spike protein from SARS-CoV-2. Firstly, in the case of the vaccines, the cells mostly break down the spike proteins into fragments. According to Health Feedback, the spike proteins generated by Covid-19 vaccines differ in three key ways to those attached to SARS-CoV-2. In actual fact, the two spike proteins behave very differently in the body. Researchers injected the spike protein into mice and found that the animals displayed neurological symptoms similar to those seen in Covid-19 patients.īut as the Health Feedback article sets out, Dr Bridle’s claim rests on the assumption that if the viral spike protein can cause damage to the cardiovascular system, then the spike protein generated in vaccinated people should be capable of the same. One study found signs of endothelial damage and fragments of SARS-CoV-2, including the spike protein, in the brains of 13 people who had died of Covid-19. There have been some studies showing that SARS-CoV-2 can damage endothelial cells, which line the blood vessels. Scientists who reviewed Dr Bridle’s claims for fact checker Health Feedback have described these assertions as misleading, as they “misrepresented the results from scientific studies and based on cherry-picked information”. Secondly, that the spike protein produced by the vaccine does not just act locally, at the site of the jab, but gets into the bloodstream and is carried to many other sites in the body. Firstly, that the spike proteins generated by the vaccine cause cardiovascular damage if they get into the bloodstream. Dr Bridle’s claimsĭr Bridle’s concern rests on two claims. The Covid-19 vaccines approved for use in the UK work by giving the body instructions on how to make the spike protein, so that if the person is later infected, their immune system can generate a response that attacks the virus (via the spike protein) faster and more effectively. This spike protein helps the virus enter cells and is also one of the ways the human body’s immune cells recognise a virus and attack it. I’m in What is the spike protein and what has it to do with vaccines?Īs we have written before, there is a protein on the surface of the SARS-CoV-2 virus (the virus which causes Covid-19), called a spike protein.
