No scientific evidence suggests that the spike proteins produced in response to mRNA COVID-19 vaccines are toxic or harmful to human organs.
The assertion was made again on the internet, most notably referring to a study published by Salk Institute, founded by Jonas Salk. The deceptive posts misrepresent the study's implications for COVID-19 vaccine safety while giving a link to the study's media release to claim the vaccines damages the vascular system. In contrast to the claim, the research investigated how the SARS-CoV-2 virus's spike proteins, which induce COVID-19, injure cells in the vascular system.
The Salk Institute's investigation concluded that COVID-19 vaccines are effective in protecting patients from the virus. The study's conclusion published in the AHS journal states, ''vaccination-generated antibody and/or exogenous antibody against S protein not only protects the host from SARS-CoV-2 infectivity but also inhibits S protein-imposed endothelial injury.''
Specialists at the Meedan Digital Health Lab told Reuters, "So far, there is no scientific evidence available that suggests spike proteins created in our bodies from the COVID-19 vaccines are toxic or damaging our organs." The article also highlights that research shows that spike proteins remain attached to the injection site's cell surface and do not travel through the bloodstream to other body parts. Liver enzymes destroy the 1 percent of vaccination that does make it into the bloodstream.
Centers for Disease Control and Prevention report states mRNA vaccines have messenger RNA strands enclosed in a unique coating. The coating shields the mRNA from enzymes in the body that would otherwise degrade it. In addition, the coating aids mRNA entry into muscle cells surrounding the vaccination site. Human cells are told to manufacture a fragment of the "spike protein" found on the surface of the SARS-CoV-2 virus by mRNA vaccinations. Because only a portion of the protein is produced, the vaccination recipient is not harmed, but it is antigenic, causing the immune system to produce antibodies. The cell destroys the mRNA strand and gets rid of it using cell enzymes after constructing a fragment of the spike protein.
The mRNA strand never penetrates the cell's nucleus and does not affect the genetic material of the vaccine recipient. The immune system creates antibodies in response to the protein or antigen present on the cell surface. These antibodies are unique to the spike protein of the SARS-CoV-2 virus, indicating that the immune system can resist infection in the future.
Carolyn Coyne, a professor of molecular genetics and biology at Duke University, told USA Today that spike proteins persist in the body for ''some time.'' On the other hand, the proteins deteriorate over time, and the vaccines are designed to prevent the proteins from binding to cells and forming new viral agents.
Global health organizations have scientifically proved that vaccines are safe. The small quantity of spike protein seen in the circulation of vaccinated persons, according to experts, does not indicate toxicity; instead, it suggests that the vaccine is working. Hence the claim SARS-CoV-2 spike protein used in the COVID-19 vaccines damages the vascular system is baseless.
