I am interested in treatment protocols (if any exist) for those who took the first 2 shots and now have regrets. I have a family member (older male with no co-morbidities except age~67) who took the PFE jab in Feb. or March...Regrets it now! Does not want boosters. So far, no ill effects of which I am aware...However, they are concerned. Is there anything that can be done to mitigate what seems to be emerging data on ill effects for those who took the shots early on? Therapies? Research?
