What conditions increase or decrease a person's risk of serious post-COVID-vaccine injuries?

1. According to Dr. Mercola, especially if someone has had prior flu vaccinations, then having these 35 diseases "... associated with XMRV infection" have higher risk of adverse events post COVID vaccinations and may benefit more by, instead, taking preventatives (Prophylaxis) like those recommended by many doctors worldwide.

2.  Anyone who has already had case of COVID has higher risk of adverse events if COVID vaccinated, In Massachusetts, according to its PCR testing (which, however, produce many false positives) HALF of the population of Massachusetts allegedly has already had a COVID case, so would be at higher risk of a serious adverse post-vaccination event.  This could include many hospital and emergency staff.

Screening People who have already been exposed to SARS-COV-2 Before Vaccine Could Protect Millions From COVID Vaccine Injuries, Surgeon Tells FDA March 2021. By James Lyons-Weiler, Ph.D.  and Robert F. Kennedy, Jr.   In this video interview, Dr. Hooman Noorchashm, surgeon and patient safety advocate, explains why he’s written a second letter to the FDA urging the agency to require pre-screening for SARS-CoV-2 viral proteins in order to reduce COVID vaccine injuries and deaths....The question of whether people who have already been exposed to SARS-CoV-2 viral proteins, as is the case with those who have had COVID, should be offered SARS-CoV-2 vaccine is inextricably tied to the question of medical ethics: The vaccination of those who are already immune is seen by many — patients and physicians alike — as unethical because it is an unnecessary, all-risk, no-benefit, medical procedure. In such cases, there are established medical grounds for grave concern. One concern is the possibility that some people who get vaccinated will experience disease enhancement, a condition that could cause them to develop more severe symptoms when exposed to the wild virus than if they hadn’t been vaccinated. ..Pathogenic priming is another concern, now confirmed by researchers at Harvard Medical School, Boston General Hospital and elsewhere... Noorchashm raises a third concern: that viral antigens may linger in antigen-presenting cells or elsewhere leading to multi-organ immunopathology in people who receive the COVID vaccines.
