Symptoms/symptom clusters were also not correlated with altered receptor antibodies [2], nor with COVID-19 reconvalescence (indicated in the case history and/or by serological NAB reactivity), nor with any particular SARS-CoV-2 vaccination regimen [2], nor with the state of SARS-CoV-2 virus immunization indicated by SAB reactivity [11]. This evidence concerns the gene SH3BP5 and COVID-19.
