She is looking at data from about the mid 1800s to the present day. Where there are variations she investigates. She was a R & D manager at a pharmaceutical company. She knows what she is talking about. In my own research. I've found that a healthy body can fight of most stuff that comes at it naturally. Be that, by eating, drinking, breathing or skin exposures. Vaccines by-pass nature's safety nets. However, conversely, a body that is not well nourished and not up to scratch cannot fight off toxins, as they arrive, in real time. This can lead to the body coating the entity, and tucking them away out of harm's way. This is my opinion and differs somewhat with the data in Sasha's essay. There are other things to take into consideration also. An injection, of any sort, has an effect on the bioelectrical within. What mRNA does, is to a certain degree, unknown. But it's not likely to be one little bit beneficial. IMO. This is somewhat borne out by the stringy stuff found in the body of corpses.** Again, it is my opinion, that a mRNA jab, destroys the negative charge of the blood and the constituents of the blood no longer have natural separation. There is also a strong possibility that the jab destroys magnesium. The result of this is calcium roaming about unsynthesized. Can then find its way into blood vessels. Hence the white strings found in blood vessels during autopsies. ** For more info on this read John O'Loony. Nature is boss OK!
