COVID-19 vaccination and immune challenges for leukemia



On 11 February 2021, CLLAN (CLL Advocates Network) and ALAN (Acute Leukemia Advocates Network) ran a free webinar on COVID-19 vaccination and immune challenges for leukemia. The webinar targeted patient advocates in the area of CLL & acute leukaemia, and we were grateful to count on an international panel of experts from different areas of specialization (two clinicians, one regulator and one virologist):

  • Professor Florence Cymbalista (France), Head Hematology Biology Department, Avicenne Hospital
  • Dr Amit Patel (UK), Consultant in Cellular Therapies and Transplantation, The Christie NHS Foundation Trust, Haematology and Transplant Unit
  • Dr Julio Delgado (The Netherlands / Spain), Seconded National Expert, Oncology Office, European Medicines Agency (EMA), Amsterdam / Department of Haematology, Hospital Clinic, Barcelona
  • Professor Uwe Gerd Liebert (Germany), Institute of Virology, Leipzig University, Leipzig


Among others, our experts gave advice on the following topics:
– Safety and efficacy of the COVID-19 vaccines in patients with immune challenges
– Roll-out of vaccines in the patient communities
– Specific challenges of CLL and Acute Leukemia patients

The meeting was moderated by Zack Pemberton-Whiteley (Chair – Acute Leukemia Advocates Network, ALAN) and Pierre Aumont (vice-chair – CLL Advocates Network, CLLAN).
