The vaccines may cause prion diseases and dementia.

According to Web MD, Prion Diseases are rare:

“Prion diseases are a group of different conditions that affect your brain and nervous system. They can cause severe dementia or problems with body control that get worse very quickly. They’re rare — the U.S. has only about 350 cases of prion diseases each year.”

As of October 2020, this was the FDA’s working list of possible adverse events. The people getting the shots did not get this information (informed consent).
