Background Children with cancer are not at increased risk of severe SARS-CoV-2 infection; however, adults with haematological malignancies have increased risk of severe infections compared with non-haematological malignancies. Methods We compared patients with haematological and non-haematological malignancies enrolled in the UK Paediatric Coronavirus Cancer Monitoring Project between 12 March 2020 and 16 February 2021. Children who received stem cell transplantation were excluded. Results Only 2/62 patients with haematological malignancy had severe/critical infections, with an OR of 0.5 for patients with haematological compared with non-haematological malignancies. Interpretation Children with haematological malignancies are at no greater risk of severe SARS-CoV-2 infection than those with non-haematological malignancies. Children have a very low risk of developing severe SARS-CoV-2 infections. Early in the pandemic it became clear from the experiences in China, Italy and Spain that this was also true for children with cancer. Not so for adult patients particularly those with haematological malignancies who were considered to be ‘extremely vulnerable’. The recommendation however, from the UK’s national Childhood Cancer and Leukaemia group (CCLG) in 2020 was that, other than particularly high risk patients (those with multiply relapsed disease or undergoing bone marrow transplant or CAR-T therapy) children with cancer, including those with haematological malignancies, need not be considered extremely vulnerable. This clearly written, concise paper by Millen et al compares patients with haematological and non-haematological malignancies enrolled on the UK Paediatric Coronavirus Cancer Monitoring Project from March 2020 until Feb 2021 and supports that recommendation.
