Marc Girardot puts the case, something being made more frequently, that the Covid vaccines can be dangerous to pregnant women, babies and a threat to human reproduction. The material below is his hypothesis of how this would operate as a general theory. In summary, the idea is that injected vaccine material, whether mRNA or otherwise, will not stay at the deltoid muscle injection site, as has been shown by the early biodistribution studiers done by Pfizer, and demanded by the Japanese government. Circulating biomaterial will disrupt the local endothelial ecosystem. Repair may not be possible and if as is occurring frequently, damage occurs in the heart, this will be to the aorta or the large arteries, leading to endothelial wall destruction, coagulation, progressive destruction of smooth muscle cells, subsequent arterial rupture, haemorrhage, as well as blood clots. The same sort of destructive process could operate in the reproductive system as well.
