For any medical procedure we need to have fully informed consent, and part of that involves knowing exactly what the risks are. For example, a friend had a hernia and went to the hospital to check out surgery. It is done using a synthetic mesh. As my friend had allergies to many synthetic products, I told him to ask what the mesh was made of. The surgeon did not know, and looked it up on the net. Sure enough it was something that might have killed him via anaphylactic shock. Anyway, here is an update from Dr Mercola, the best around, on all one needs to know on the risks associated with the Covid vaccines. It is, as always, one opinion, and one always needs to make up one’s own mind after due consideration of all evidence.
