The "Corona Virus Information Center" is claiming that vaccines are "throughly tested for safety." Now there is no long term safety data for this thing. Absolutely not true.
The standard safety standard would at least be as good as the standard three year period of safety data and of animal studies. This didn't happen. To me the placebo should be saline solution with distilled water in such studies. This is not always even the case.
Although you may not get COVID itself, and at this point I doubt any of these three statements are necessarily true, it is admitted that the way it works is turning the cells in the body into S-protein factories. The S-protein itself has been found to be the dangerous part of the disease. With this protein causing cardiovascular problems.
