It always pays to read the study itself, especially the “Discussion” section.

Their “oral vaccine” wasn’t tested orally. The test material was *injected into the duodenum* meaning that it wasn’t subjected to stomach acids:
“To further confirm the ability to stimulate neutralizing antibodies, RBD mRNA-milk-exos were injected into the duodenum”
The authors admit that their proposed technology is challenging even in a lab setting. “Low yield”, “scaling up production difficult”:
“the practical application of exosome-based therapeutics in clinical transformation remained an ongoing challenge. Many studies isolated exosomes from cell culture media with a low yield and cost, making scaling-up production difficult”
The authors say that their study “suggested beneficial results”; and that they need to expand the number of animals in future studies to verify results:
“Although the results from this study suggested the beneficial effects of an oral vaccine for the prevention of the novel coronavirus and offered a potential regimen for clinical application, we needed to expand the number of animals and further verify the efficacy of the oral vaccine in different animal models (such as large animals) in future studies. Furthermore, the precise molecular mechanisms and safety needed to be investigated further.
The authors tell you that their technique is incompatible with large scale production:
“the technique used in this study to purify exosomes is incompatible with large-scale exosome production, which is one of the obstacles to the progress of industrialization.
And the final paragraph of their discussion is just wishful thinking:
“It will come soon that an mRNA delivery system based on milk-derived exosomes will serve as a platform for mRNA therapeutics development in the recent future.”
The point is, they are trying and it’s just a matter of time before technology allows them to do what they are planning that is morally so wrong and bankrupt they should burn in hell forever for even seriously considering it.
Do you really want the powers that be to engage in that kind of actions against YOU without your knowledge or consent?
Because unless you are one of them, YOU, along with the rest of us, are the targets of their plans. Do you really think that they are doing this out of the goodness of their hearts and with our best interests in thier minds?
