COVID-19 Vaccine Allergy Safety Track (VAS-Track) pathway: real-world outcomes on vaccination rates and antibody protection

Misdiagnosed vaccine-related “allergies” lead to unnecessary vaccine deferrals and incomplete vaccinations, leaving patients unprotected against COVID-19. To overcome limitations and queues for Allergist assessment, the “VAS-Track” pathway was developed to evaluate patients via a multi-disciplinary triage model including nurses, non-specialists, and Allergists.

Thrombosis with thrombocytopenia after the second ChAdOx1 nCoV-19 vaccination: A possible immunological mechanism independent of anti-platelet factor 4 antibody

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a distinctive syndrome characterized by unusual site thrombosis accompanied by thrombocytopenia following adenoviral vector vaccines against severe acute respiratory syndrome coronavirus 2. Platelet-activating anti-platelet factor 4-dependent antibodies (anti-PF4 Abs) have been identified as pathogenic antibodies in almost all patients.
