The pharmacological effect of the vaccination does not occur right away, but gradually over a period of 2-6 weeks, similar to the Covid vaccines from Moderna and Pfizer, and requires subsequent booster vaccinations.
“The zona pellucida (ZP) is a glycoprotein membrane that surrounds all mammalian eggs. Certain proteins in the membrane serve as the sperm receptor. The contraceptive vaccine produced by the SCC uses the ZP from the pig, thus the name porcine zona pellucida (PZP).
“Briefly, the PZP is produced by a complex process whereby the ZP is removed from the ovum, its glycoproteins extracted, isolated, and converted into a vaccine. The vaccine stimulates the target animal to produce antibodies, which attach to its own ZP, thus blocking fertilization and causing contraception.
“The PZP vaccine is usually given, initially, in a series of 2 vaccinations 2-6 weeks apart and then a booster every 8 months to a year, depending on the species. The PZP is emulsified with an adjuvant to stimulate the animal’s immune system.” It is extracted from the ovaries of pigs which is used as a source of antigens for immunocontraception.
Porcine zona pellucida has been used in wildlife contraception since the late 1980s. Animals with which PZP has been employed in this context include elephants, wild and/or feral horses, elk and white tailed deer. It can be administered to captured animals via a standard syringe or administered to free ranging wildlife with a dart gun. The initial contraceptive effect last for approximately one year in horses.
From animal reproductive health to people?
Coincidentally, Pfizer’s CEO Dr. Albert Bourla, is a trained veterinarian. He is a Doctor of Veterinary Medicine and holds a PhD in the Biotechnology of Reproduction from the Veterinary School of Aristotle University in Greece.
He joined Pfizer in 1993 in its former Animal Health Division as technical director of Greece. He held positions of increasing responsibility within the Animal Health Division across Europe, before moving to Pfizer’s New York global headquarters in 2001.
From 2014-16, Bourla served as group president of Pfizer’s global vaccines and oncology. “He was instrumental in building a strong and competitive position in oncology and expanding the company’s leadership in vaccines,” according to his biography.
Many researchers warn of sterility associated with the jabs
Dr. Elizabeth Lee Vliet stated during the second Stop the Shot online conference streamed on August 19 by LifeSiteNews that peer-reviewed scientific research from 2012 and 2018 as well as evidence from whistle-blowers showed that the jabs damaged fertility and pregnancy. It was not being reported to the public.
The vaccine nanoparticles “can pass through the blood-testis barrier, placental barrier, and epithelial barrier, which protect reproductive tissues,” she said.
Human immune cells are thus “trained to attack” a protein vital to a successful pregnancy, as in the case of PZP. Vliet warned that this would lead to “miscarriages, birth defects, and infertility” when taking the jab.
Dr. Michael Yeadon, a former vice president at Pfizer, has corroborated the claims, saying that the jabs pose a “severe risk” of infertility. Yeadon cited scientific research specifically on lipid nanoparticles, found in the shots. “Do not take these vaccines,” he warned. “There’s a severe risk to your ability to conceive and carry a baby to term.”
Although the research into nanoparticle toxicity was conducted on animals, Yeadon argued that humans were also mammals and therefore at similar risk. “If someone wants to persuade me that they’re not concentrating in human ovaries, they are going to have to provide me with some data,” he said.
The jab has also been correlated with thousands of reports of menstrual irregularities. Gynecologist Christiane Northrup warned in April this year that the Covid vaccine could cause infertility in women, because the protein Syncytin-1 present in the placenta was very similar to the Covid virus SARS-CoV-2’s spike protein.
