I wasn't sure about sharing this because It may seem like speculation (or noise), but I decided to share it anyway.
My nephew, who is a physician himself, has a pancreas cancer that was detected about 5 years ago; after being operated and treated with all types of treatments, including alternative ones, like IV vitamin C, he was following a "normal" life until 2 months ago when he started to feel tiredness, shortness of breath, pain in the legs, and a strange pain when chewing; these symptoms appeared after about 2 months of being vaccinated. So, he went for lab tests, and to talk to his doctor about this, he told my nephew that he had to undergo further tests; the results showed clearly his condition: ALS (Amyotrophic lateral sclerosis) which is a progressive nervous system disease that affects nerve cells in the brain and spinal cord, causing loss of muscle control, and it is sadly a fatal disease.
I hesitated to share this because not much has been said about the relationship between the vaccine and this disease, but to be honest, I wouldn't be surprised if there is a direct link.
