Chinese researchers have developed a new oral Wuhan coronavirus (Covid-19) “vaccine” for cows that causes the animals to produce mRNA poisons right in their milk.
Citing claims that covid is still allegedly presenting “numerous challenges to global health,” the Chinese scientists came up with a new way to vaccinate people via the food supply.
Their paper explains that the oral mRNA vaccine is based on “bovine milk-derived exosomes,” or milk-exos, that encode the SARS-CoV-2 receptor-derived binding domain (RBD) as an immunogen.
They found that RBD mRNA delivered through milk-derived exosomes is capable of producing secreted RBD peptide in 293 cells in vitro, as well as stimulating neutralizing antibodies against RBD in test mice.
“These results indicated that bovine milk-derived exosome-based mRNA vaccine could serve as a new strategy for preventing SARS-CoV-2 infection,” the study abstract explains. “Meanwhile, it also can work as a new oral delivery system for mRNA.”
Verification of oral vaccines for RBD mRNA-DC-milk-exos in vitro and in vivo
We next tested whether Milk-exos loaded with RBD mRNA could deliver functional RBD mRNA into human cells. Western blot and ELISA results established that RBD mRNA-loaded Milk-exos could deliver mRNA into 293 cells and produce RBD peptide 24 hr later.
To further confirm the ability to stimulate neutralizing antibodies, RBD mRNA-milk-exos were injected into the duodenum (i. d.) of 9-11-week-old female BALB/c mice (Fig. 6A). Blood (0.1 mL) was collected on days 0, 7, 14, 21, 28, 35, 42, and 49 for antibody detection before the animals were sacrificed. Using ELISA kits adapted for detecting mouse-derived antibodies, we observed that vaccinated animals produced a relatively constant level of neutralizing antibodies against RBD after the second injection
Discussion
In this study, we demonstrated that an oral vaccine for SARS-CoV-2-based bovine milk-derived exosomes could deliver functional mRNA in vitro and in vivo and induce anti-S antibody responses. We first successfully verified the technical feasibility of oral mRNA delivery based on bovine milk-derived exosomes as delivery vehicles.
Compared with injection, oral administration was generally considered to have a better safety profile, better patient compliance, and lower medical costs (20, 22). Like liposomes, exosomes have a bi-lipid membrane and an aqueous core; therefore, they could potentially be loaded with hydrophilic and lipophilic drugs .

Even though I don't support what they do, I think only raw milk would be a problem?
Antibodies undergo denaturation when heated. It's not good they experiment with that and I really dislike the "better patient compliance" part of it.
