Це як я розумію було сказано десь влітку, а зараз набирає обертів шкандаль що нібито нові вакцини виробляють імунітет проти сінтецину - білку, який:
"Syncytin-1 also known as enverin is a protein found in humans and other primates that is encoded by the ERVW-1 gene (endogenous retrovirus group W envelope member 1). Syncytin-1 is a cell-cell fusion protein whose function is best characterized in placental development. The placenta in turn aids in embryo attachment to the uterus and establishment of a nutrient supply."
Immune responses in COVID-19 are directed against many antigens, including the spike protein, and the intensity of the immune response is far greater than what can be expected from a COVID-19 vaccine.
1. As Cosma et al write: Severe acute respiratory syndrome coronavirus 2 infection during the first trimester of pregnancy
does not seem to predispose to early pregnancy loss; its cumulative incidence did not differ between women with spontaneous abortion and women with ongoing pregnancy.
2. Rotshenker-Otsinka et al also add: The COVID-19 pandemic environment
does not seem to affect early first-trimester miscarriage rates in asymptomatic patients.
3. And there’s even a recent cohort study by Adhikari et al: In this cohort study of
252 SARS-CoV-2–positive and 3122 negative pregnant women tested in outpatient and inpatient settings at a large county medical center, adverse pregnancy outcomes were similar, and neonatal infection occurred in 3% of infants, predominantly among infants born to asymptomatic or mildly symptomatic women.
Placental abnormalities were not associated with disease severity, and the rate of hospitalization was similar to rates among nonpregnant women.
In addition to this, the argument is weakened by several other lines of evidence. Firstly, for vaccines containing the receptor-binding domain only, there should not be any expected sequence homology between syncytins and the spike protein, because the receptor-binding domain is not the region of the protein which mediates viral fusion (rather, it is a region between the S1 and S2 regions of the protein, and it requires enzymatic processing to expose this site so that fusion can occur).
І так далі.
There is a sequence of 5 amino acids (there is a divergence for one of them, or else it would be 6) which is shared between the spike protein and the syncytin-1 protein:
А відмінність навіть одної амінокислоти в нитці білку може повністю змінити специфічність до антитіла
Висновок:
In short, the claim that the vaccines for COVID-19/SARS-CoV-2 will cause infertility because of some kind of crossreactive immune response between the spike protein antigens and syncytin proteins is baseless. You should get these vaccines without fear of what they may do for your fertility.-------------------------------
