Vidcast:  https://youtu.be/aJjQSnjvQXI   Fewer than 1% of patients recovering from CoVid19 produce the highest concentrations of virus neutralizing antibodies.  A just-published study from New York’s Rockefeller University analyses the antibodies from 149 recovered CoVid patients and controls.   The quantity of CoVid neutralizing IgG antibodies were measured at 39 days following each subject’s onset of symptoms.  The concentration of useful antibody was less than 1:1000 in 79% of subjects.   The conclusion is that most CoVid19 infections induce only a moderate protective antibody response.  They also create T-cell immunity, and we hope that such energized killer cells may confer lasting CoVid immunity.  For now protect yourself with masking, distancing, washing.   https://www.nature.com/articles/s41586-020-2456-9_reference.pdf   #covid #antibodies #covidimmunity
