If you did even a tiny bit of fact checking you would have learned that you are sharing a debunked fake post that was constructed to deceive people and it has done so. I have heard friends at a recent dinner meeting saying how they heard that the vaccine will make women sterile all based on the foolishness of the fake posts shared on the internet. (shall I say PROPAGANDA) that you are adhering to. But rather than be so sure of your "Wild Assumptions" please read the following as a starting place to dig deeper into the facts behind syncytin-1 to make an educated decision on what is true and who are the real evil liars who post lies on the internet and laugh at those who fall for them.
What is syncytin-1?
In February 2000, researchers at the
now-defunct Genetics Institute in Cambridge, Massachusetts,
discovered a gene, residing within the human genome, containing hallmarks of a recently discovered human endogenous defective retrovirus.
The protein encoded by the viral gene was produced only by cells of the
placenta – an organ made only during pregnancy that exchanges oxygen and nutrients from mother to fetus – that come into direct contact with the uterus. A sturdy bond between maternal uterine and fetal placental cells was entirely dependent on this protein, which the researchers called syncytin from the word
syncytium, a cell-like structure formed from the joining of many other cells.
Later research discovered that humans were not the only ones carrying this anchoring protein: Chimpanzees, gorillas, orangutans and gibbons possessed the same gene along the same spot in their genomes. Syncytin was also found in other mammals, although the gene did not appear to originate from the same virus.
A second syncytin was identified by French virologist Dr. Thierry Heidmann and colleagues in 2003. Both syncytins – dubbed syncytin-1 and 2 – were important for placenta formation, but syncytin-2 played an additional role in preventing the mother's immune system from attacking the fetus, a typical reaction of any healthy immune system when confronted with a foreign presence
Pfizer-BioNTech and
Moderna's COVID-19 vaccines both use
messenger RNA, a single-strand of genetic code that provides manufacturing instructions for a particular protein, much like a recipe. For the vaccine, the recipe is for SARS-CoV-2's spike protein, which cells will mass produce, triggering and teaching the body to make antibodies in response.
The mRNA degenerates once its purpose is fulfilled, but the
anti-SAR-CoV-2 spike protein antibodies live on to fight future infection.
(the antibodies live on, not the spike proteins)
While the coronavirus spike protein and syncytin-1 do share a minute string of amino acids – the building blocks of proteins – the similarity is too small to warrant an immunologic offensive, said virologist Dr. Ian Jones of the University of Reading, United Kingdom, to FullFact.org.
