People are concerned about a synthetic spike protein being transferred similar to shedding, not the viruses its self like some traditional vaccines. They do admit the spike protein can be found in blood and other bodily secretions just not in large amounts. I would say we can't be so sure of much just yet. Perhaps some people have a larger dump of the protein for reasons or some other phenomenon we haven't picked up on. Either way I do hope someone is recording data on the cyclical phenomena women are experiencing because it is important whether caused by something natural, collective stress or due to vaccines/some kind of transfer.🖖🏽 Some call a women's cycle her Fifth Vital Sign because we often do see changes when something is off...there is plenty of "mechanism" and science to back this up.
