Key studies

  • COVID-19: 10-day injections: A small trial reported fewer hospital deaths; replication is needed. (source)
  • COVID-19: five-day injections: Immune and inflammation markers improved in an open-label trial. (source)
  • COVID-19 antibodies at 104 days: Antibody levels fell less after Thymalin; protection from reinfection was not tested. (source)
  • COVID-19 antibodies at 200 days: A follow-up report described higher antibody levels after Thymalin. (source)
  • COVID-19 immune markers at six days: Retrospective analysis of immune-marker changes, not a new survival trial. (source)
  • COVID-19: clotting and mortality: A comparative report found lower mortality with Thymalin; causal certainty is low. (source)
