I recently received my results from the John Hopkins study and I have antibodies. I have had additional antibody testing levels done at my own expense just as piece of mind. My husband also had his antibodies checked after his second shot. We are both past the 10-14 days so according to the CDC we are fully vaccinated. I had Pfizer and my husband had moderna. I actually had more antibodies than my husband who is in perfect health and only takes a multivitamin. Our second shots were 2 days apart and we are well over a month out. So I found that interesting considering the hypothesis that I would create fewer antibodies because of all my immunosuppressive meds (I am on several for transplant, PSC and Crohn’s disease.) Just wanted to share my experiences so far.
