The Covid vaccine injuries resemble long Covid in terms of their underlying pathology. I belong to the Neuro V Long-Haulers Facebook group. On that site, a famous Danish physician with expertise with both chronic fatigue syndrome and vaccine injuries recommended a drug for a patient with a history of EBV who was suffering from neurological symptoms after the Covid vaccine. I think the drug was an antiviral against the reactivated EBV due to immune dysfunction caused by the vaccine. Similarly, immune dysfunction has been linked to long Covid, so you could also have reactivated EBV.
