I did test positive...but did not have any additional blood work to check for antibodies. Since I also had the monoclonal antibodies, I must assume that I have antibodies either from the virus itself and/or the infusion. I continue to have shortness of breath—not severe but noticeable when I walk up the stairs, etc., and I've concluded that all are related. As mentioned above there is slow improvement in iron/ferritin blood levels but the numbers hover just above the line of demarcation between normal and below normal range. As a side note, the government seems only to be honest when it suits the circumstances and, even then, I doubt that there is ever complete honesty.
