"We made a big mistake, and didn't realize it until now. [...] We thought the spike protein was a great target antigen but never knew the spike protein itself was a pathogenic toxin protein. [...] By vaccinating people we are inadvertently inoculating them with a toxin."
At least, that's according to Dr. Byram Bridle who is referencing this peer reviewed research paper from Japan (I don't read of word of Japanese so I have to take his word for it) https://www.pmda.go.jp/drugs/2021/P20210212001/672212000_30300AMX00231_I100_1.pdf#page11
If accurate, cutting edge research that tracks the movements of various proteins throughout the body has been done on patients receiving the COVID mRNA vaccines and discovered that the spike proteins that are generated don't always stay in the shoulder muscles as previously assumed but can get into the blood stream and spread to the brain, bone marrow, liver, adrenal glands and spleen with high concentrations in the ovaries.
Further research also alleges that the part of COVID-19 that causes vascular and neurodegenerative problems is in fact the spike proteins that we are now teaching the body to produce via the "vaccinations". It's believed by some that this means that if the spike proteins your body produces leave the muscle tissue complications with these can lead to blood clots and a myriad of other symptoms currently being reported as side effects of the vaccine.
Take it all with a grain of salt as I have no way of verifying any of this, but if true it could be a very good reason to wait to see what the long term affects of the mRNA gene therapy are that they are trying so desperately to give everyone.
