Just as Improvac ultimately targets gonadotropin-releasing hormone as a way to “castrate” male pigs or suppress ovarian function in female pigs, it turns out the infamous spike protein from SARS-CoV-2—the virus that supposedly causes COVID-19—also targets GnRH.
In the video above from 2009, Bourla touts “Improvac,” which he claims is “the world’s first vaccine for the control of boar taint.” And while the endpoint of efficacy for the “vaccine” is the elimination of “boar taint”—that is, the offensive odor or taste that can be evident during the cooking or eating of pork or pork products derived from non-castrated male pigs—he notes “its efficacy is… as good as… physical castration.”
Bourla goes on to note the injection “exceeds 99% of success” and went through 130 clinical trials(!!!).
As the European Medicines Agency (EMA) notes in the excerpt immediately below, Improvac is “an immunological medicine” that aims to mitigate the natural production and build-up of androstenone and skatole. Androstenone is a steroidal pheromone that’s found in male boars’ saliva. Skatole is a byproduct of intestinal bacteria or bacterial metabolite of the amino acid tryptophan. (Note: It’s unclear why Bourla refers to Improvac as a “vaccine” while the EMA refers to it as a “medicine.”)
To prevent the buildup of androstenone and skatole, “Improvac is used as an alternative to physical castration (removal of the testes) to reduce the presence of these compounds,” in turn, also reducing “aggressive and sexual (mounting) behavior in pigs.”
What is Improvac and what is it used for? Improvac is an immunological medicine used in male pigs to reduce 'bore taint' in the meat obtained from them after slaughter. Boar taint is the offensive odor or taste which may be present in pork or pork products from non-castrated mature male pigs. Boar taint is caused by the production and build-up of the natural compounds androstenone and skatole in the fat of these animals. Improvac is used as an alternative to physical castration removal of the testes to reduce the presence of these compounds. Improvac also reduces aggressive and sexual mounting behavior in pigs.
The EMA also notes that Improvac can be used in female pigs, where it’s “intended… to temporarily suppress ovarian function (suppression of oestrus) in order to reduce the number of unwanted pregnancies…” (Oestrus is the period in the sexual cycle of female mammals.)
In the video immediately below from Pfizer Animal Health, posted to YouTube by animalpharmnews in 2009, the way Improvac works in the male boar’s body is described and shown. We see that the way the “vaccine” (or “medicine”) works to mitigate androstenone and skatole (although more circuitously in the latter compound’s case), is by delivering “an antigen” that mimicks GnRH; that is, gonadotropin-releasing hormone. This is referred to as a “GnRH analogue.”
As the video shows, GnRH is responsible for the “cascade” of chemicals that leads to the release of androstenone and testosterone from the testes when it itself is released from the hypothalamus, travels through the bloodstream, and arrives at the pituitary gland, where it binds to a specific GnRH receptor. Once the GnRH binds to the receptor, there’s a release of two hormones—luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These two hormones then travel to the testes, where they trigger the release of androstenone and testosterone.
