Even a cursory look at social media demonstrates that there are three main areas of concern around Covid vaccines at the moment: clotting disorders; abnormal menses; and the possibility that those that are vaccinated are transmitting that vaccine material.
There are of course other significant concerns not least neurological damage following receipt of the vaccine but, as you will see, that may be as a consequence of one of the other three.
Only one of these concerns is recognised by governments and health agencies at the moment – clotting disorders; the other two are not.
