Recent reports have suggested that approved corona vaccines cause infertility. New research now denies such a problem.
When the World Health Organization identified Covid-19 as a pandemic virus in March 2020, no one expected the virus to have a significant impact on people’s daily lives. Even before the announcement, research teams and drug companies around the world had begun the difficult stages of producing the Covid-19 vaccine.
Eventually they managed to make the vaccine available to the public. However, the approved vaccines have received a great deal of misinformation to date, which is why people find it difficult to trust these vaccines, and as a result, the vaccination process is becoming increasingly difficult.
Eight vaccinologists and biologists have recently commented on the claim that corona vaccines cause infertility.
How do corona vaccines work?
Like all other vaccines, Covid-19 vaccines work by activating the immune response. Covid-19 vaccines expose a safe version or small portion of the virus to the immune system, causing it to produce antibodies that can prevent infection in the future. The difference between these vaccines is in how they affect the corona virus or different parts of it. Many vaccines target the protein horn of the virus as their primary target.
The protein spike or tentacle protein is located on the surface of the virus and is the main target of the immune system during infection. Newer vaccines, such as Pfizer and Moderna, use genetic or aranic materials to identify this protein. The Astrazenka vaccine, on the other hand, uses DNA.
When did the concern about infertility of these vaccines arise?
The issue of Covid-19 vaccines causing infertility was raised through several posts on social media, most of which were later referred to as misinformation.
While further explanation of how the vaccine works in infertility has been obscure, most posts have linked the Pfizer vaccine to a protein called syncytine 1 found in the placenta. According to the posts published in this article, either vaccines contain syncetin 1 or the tentacles of the protein that is part of the vaccine are similar to this protein.
However, there was concern that the vaccine would boost the immune system and continue to attack the placenta. The placenta is an organ in the body that attaches to the fetus with a umbilical cord.
Is there a link between Covid-19 and syncetin 1 vaccines?
Since all the ingredients of the vaccine are in the public domain, it is easy to see that syncytine 1 is not present in this compound. The similarity between syncytine 1 and spike protein is not sufficient to induce any immune response automatically. All proteins are made up of long strands of amino acids that go into complex three-dimensional shapes.
“In order for antibodies to mistakenly identify syncytine-1 as the Covid-19 virus, the amino acids in these substances must be similar enough that they are not, and vital amino acids must be present,” explains Professor Katherine Thornton of Swansea University. “Three-dimensional molecules come together in a very similar and accessible way, which is not the case.”
It is well known that antibodies do not attack the fetal placenta during their response to the Covid-19 virus spike protein because antibodies to the virus have been observed in newborns. In fact, antibodies during pregnancy are passed from mother to baby through the placenta.
“After RNA fragments are converted to amino acids, which are the building blocks of proteins, they are rapidly broken down at the injection site,” explains Dr. Lee Riley of the University of California, Berkeley. “So they have no chance of moving to another part of the body and will not affect fertility.”
All approved Covid-19 vaccines have been successfully tested on animals and have shown no effect on their fertility. There is also no data from human clinical trials that specifically determine the effect of vaccines on fertility.
Despite all these criteria, 53 cases have been tested in pregnant women in clinical trials of modern vaccines, Pfizer and Astraznka. The results of this test show that the vaccines had very little effect on fertility or pregnancy.
However, all the experts who participated in this study deny the effect of corona vaccines on fertility.
